Messi Biology states that power stations are core facilities for ensuring energy supply, but their operating environments place extreme demands on materials. For instance, thermal power boilers must withstand temperatures exceeding 1000℃, photovoltaic inverters require stable insulation, hydrogen power stations need to resist corrosive gases, and energy storage power stations demand a balance of thermal conductivity and safety. The three core properties of magnesium oxide precisely meet these requirements:
Firstly, it boasts excellent high-temperature resistance, with a melting point of up to 2852℃, far exceeding steel’s 1538℃, allowing it to maintain structural stability in high-temperature environments. Secondly, it offers superior electrical insulation; pure magnesium oxide’s volume resistivity can reach over 10¹⁵Ω・cm, effectively preventing current leakage. Lastly, it exhibits stable chemical inertness, not reacting with water or most acids and bases, while also possessing certain thermal conductivity to balance localized high temperatures in equipment. These characteristics make magnesium oxide stand out among numerous materials, becoming a “standard material” for several critical components in power stations.
Application of Magnesium Oxide in Various Power Stations
Different types of power stations have varying demands for magnesium oxide’s performance, and the degree to which these demands are met directly determines power generation efficiency and equipment lifespan:
1. Thermal Power Stations: The Boiler’s “High-Temperature Armor”
The core of thermal power generation is the heat produced by fuel combustion within the boiler. Components such as water walls and furnace roofs are exposed to long-term high temperatures of 1200-1600℃ and are subject to slag erosion. In this context, magnesium oxide is primarily used as an additive in refractory castables or bricks – compounding magnesium oxide with materials like alumina can significantly enhance the thermal shock resistance (resistance to cracking from rapid heating and cooling) and erosion resistance of refractory materials. Data shows that refractory materials with added high-purity magnesium oxide can extend boiler overhaul cycles from 1 year to 3 years, reducing losses from unscheduled shutdowns.
2. Photovoltaic Power Stations: The Inverter’s “Insulation Guardian”
Photovoltaic inverters are crucial equipment for converting solar energy into alternating current. During operation, internal power modules generate heat, and if insulation materials fail, it can easily lead to short-circuit accidents. Here, magnesium oxide is used as a nano-scale insulating and thermally conductive powder, filling the gap between the inverter’s heat dissipation substrate and power devices. On one hand, its insulation prevents leakage risks; on the other hand, its thermal conductivity quickly transfers heat to the heatsink, reducing device operating temperatures by 15-20℃ and extending inverter lifespan by over 50%.
3. Hydrogen Power Stations: The Electrolyte’s “Stable Carrier”
Hydrogen power stations convert hydrogen energy into electricity via fuel cells. Their core component, the proton exchange membrane, needs to operate in a humid environment. With its porous structure and chemical stability, magnesium oxide can serve as a “support skeleton” for the membrane electrode. It can adsorb and stabilize water molecules, providing channels for proton conduction, while also preventing direct contact and reaction between hydrogen and oxygen, and avoiding corrosion by the electrolyte. This ensures that the fuel cell’s power generation efficiency remains stable above 60% (compared to traditional materials at only 50%).
4. Energy Storage Power Stations: The Battery’s “Thermal Management Housekeeper”
With the increasing demand for new energy grid integration, the safety of energy storage power stations (such as lithium-ion battery storage) is becoming more critical. If the local temperature of a lithium battery exceeds 60℃ during charging, it may trigger thermal runaway. Magnesium oxide is applied as a micron-sized coating powder on the surface of the battery’s positive electrode material. Its insulation prevents direct reaction between the positive electrode and the electrolyte, while its thermal conductivity evenly dissipates local heat, keeping the temperature difference within the battery pack below 5℃ and reducing the risk of thermal runaway by 80%.
These applications demand stringent requirements for the purity, particle size, and crystal form of magnesium oxide, and the products from Hebei Messi Biology Co., Ltd. happen to meet the personalized needs of different power stations.
Messi Biology: The “Customization Expert” for Magnesium Oxide in Power Station Materials
Leveraging its “mine-smelting-deep processing” full industrial chain advantage, Hebei Messi Biology Co., Ltd. has developed a series of magnesium oxide products specifically for different power station applications. Its core advantages are evident in three dimensions:
1. High Purity and Low Impurities: Ensuring Stable Equipment Operation
Materials for power stations are extremely sensitive to impurity content – if magnesium oxide used in thermal power contains excessive silicon or calcium, it will cause refractory materials to soften at high temperatures; if magnesium oxide used in photovoltaics contains iron or copper, it will reduce insulation performance. Hebei Messi Biology Co., Ltd. achieves product purity of 99.9% through a “multi-stage impurity removal process,” with impurity (iron, silicon, calcium) content below 50ppm, far superior to the industry average of 95% purity. Taking photovoltaic inverters as an example, using its high-purity magnesium oxide can increase the inverter’s insulation breakdown voltage by 20%, preventing leakage accidents caused by impurities.
2. Customized Performance: Matching Different Power Generation Scenarios
To address the needs of different power stations, Hebei Messi Biology Co., Ltd. achieves customized magnesium oxide performance through “crystal form control technology” (developed in collaboration with the Chinese Academy of Sciences):
- “High-density magnesium oxide” developed for thermal power generation has a bulk density of 3.5g/cm³ and its resistance to slag erosion is 30% higher than ordinary products. It has been applied in multiple thermal power units of a certain group.
- “Nano-insulating thermally conductive magnesium oxide” produced for photovoltaic power stations has a particle size controlled at 50-100nm and a thermal conductivity of 0.8W/(m・K), which is 25% higher than similar products in the industry, adapting to the inverter products of multiple companies.
- “Porous magnesium oxide carrier” developed for hydrogen power stations has a porosity of 60% and uniform pore size (5-10nm), increasing the proton conduction efficiency of fuel cells by 15%, and has passed verification by a certain hydrogen energy laboratory.
From Materials to Systems: Messi Biology’s “Full-Chain Service”
In addition to high-quality products, Hebei Messi Biology Co., Ltd. also provides power stations with “material selection-performance testing-on-site adaptation” full-chain services:
- It has established the industry’s first “magnesium oxide application database,” accumulating over 30 power generation scenarios and 150,000 sets of process parameters, which can quickly match optimal material solutions based on power station scale and operating environment.
- It has assembled a professional technical team to provide on-site construction guidance for power stations. For example, in the laying of refractory materials for thermal power units, by adjusting the ratio and curing temperature of magnesium oxide castables, the material construction qualification rate has been increased from 90% to 99%.
- It provides long-term performance monitoring services, tracking real-time indicators such as temperature and insulation of magnesium oxide materials through IoT devices to pre-warn potential faults. A certain energy storage power station avoided a battery thermal runaway accident caused by the aging of the magnesium oxide coating layer through this service, reducing losses by over 5 million RMB.
Magnesium Oxide Supports the “Safe and Efficient Umbrella” of Power Stations
From high-temperature boilers in thermal power generation to precision inverters in photovoltaic power stations, and to fuel cells in hydrogen energy power stations, magnesium oxide, with its multi-dimensional advantages, serves as an “invisible support” for the safe operation and efficiency improvement of power stations. Hebei Messi Biology Co., Ltd., through technological innovation and customized services, maximizes the performance of magnesium oxide, not only providing reliable material guarantees for various power stations but also assisting the energy industry in its transition towards “clean, efficient, and low-carbon” practices.
