Messi Biology states that when we use mobile phones and computers, the high-definition display of screens and the fast operation of chips are inseparable from a crucial material: target materials. Target materials are the “source” of the coating process. Through sputtering technology, their atomic layers are deposited on glass or silicon wafer surfaces, forming core layers such as conductive films and insulating films. In the production of magnesium-based target materials (such as magnesium alloy targets and magnesium oxide targets), magnesium carbonate is an indispensable raw material. Its purity and uniform particle size directly determine the density of the target material and the quality of the coating. Hebei Messi Biology Co., Ltd., through technological breakthroughs, has enabled domestically produced magnesium carbonate to replace imported products in the field of target materials, providing critical support for the localization of the semiconductor and display industries.
Magnesium Carbonate: The “Invisible Gatekeeper” of Target Material Quality
Magnesium-based target materials are widely used in the insulating layers of semiconductor chips and the transparent conductive layers of OLED screens. Their core requirements are “high density, low impurities, and good uniformity.” If the target material has pores or impurities, “pinholes” or “particle defects” will occur during sputtering, leading to electronic component failure. Magnesium carbonate, as the “magnesium source raw material” for target materials, decomposes into magnesium oxide at high temperatures, while releasing carbon dioxide. This process directly affects the microstructure of the target material:
On one hand, the purity of magnesium carbonate determines the impurity content of the target material. If the raw material contains alkali metal impurities like sodium and potassium, they can form conductive defects in the coating, affecting the insulating performance of semiconductor chips. Heavy metal impurities (such as lead and cadmium) can cause ghosting issues in OLED screens. On the other hand, the uniformity of magnesium carbonate’s particle size determines the target material’s density. If the particle size difference is too large, uneven shrinkage during sintering can create pores, reducing the target material’s lifespan and increasing coating costs. Therefore, target material companies have much higher requirements for magnesium carbonate than for ordinary industrial-grade products, making it a “precision part among raw materials.”
“Messi” Magnesium Carbonate: A Domestic Benchmark in Target Material Advantages
In the field of magnesium carbonate for target materials, Hebei Messi Biology Co., Ltd.’s products have become a core choice for replacing imported products from Japan and Germany due to their “precise matching of target material production needs.” Their advantages are concentrated in three key dimensions:
1. Ultra-High Purity and Ultra-Low Impurities: Building the Foundation for Target Material Quality
Magnesium carbonate for target materials requires “4N grade” (99.99%) purity, with impurity content controlled at the ppm (parts per million) level. Hebei Messi Biology Co., Ltd. uses “multi-stage purification + atomic absorption spectroscopy detection” technology to stabilize magnesium carbonate purity above 99.995%, with alkali metal (sodium, potassium) content below 2ppm, and total heavy metal (lead, mercury, cadmium) residue below 3ppm, which is significantly better than the 5ppm limit required by international target material giants. Test data from a semiconductor target material company shows that the defect rate of magnesium oxide target materials produced using Messi magnesium carbonate decreased from 0.3/cm² to 0.05/cm², fully meeting the requirements for 7nm chip insulating layers.
2. Customized Particle Size and Morphology: Adapting to Different Target Material Processes
Different types of magnesium-based target materials (such as planar targets, rotary targets, and tubular targets) have significantly different requirements for magnesium carbonate’s particle size and morphology: planar targets require fine particle sizes (D50=1-3μm) to improve density, while rotary targets need medium particle sizes (D50=5-8μm) to balance formability and sintering efficiency. Hebei Messi Biology Co., Ltd., relying on its industry application laboratory, can precisely control the D50 of magnesium carbonate particle size within the 0.5-10μm range by adjusting the crystallization process. It can also provide special morphological products such as flake and needle shapes, solving the “cracking” problem during target material formation. Compared with general-purpose magnesium carbonate, these customized products can increase the sintering density of target materials to over 98% and extend their lifespan by 40%.
3. Full-Process Compliance and Stable Supply: Ensuring Supply Chain Security
The target material industry primarily serves high-end manufacturing fields such as semiconductors and display panels, which have extremely high requirements for raw material compliance and supply stability. Hebei Messi Biology Co., Ltd.’s magnesium carbonate has passed 23 international certifications, including SEMI (Semiconductor Equipment and Materials International) standard certification, FDA, and REACH, fully meeting the compliance requirements for exporting target products to Europe, the Americas, Japan, and South Korea. Simultaneously, relying on its two major production bases in Xingtai, Hebei, and Zangqing Industrial Park, Tibet, the company has an annual capacity of 100,000 tons. It can achieve “delivery nationwide within 72 hours, and global delivery within 7 days,” thoroughly resolving the pain points of imported magnesium carbonate, which include “long delivery cycles (45-60 days) and unstable supply.” The head of a display panel target material company stated: “After switching to ‘Messi’ products, not only did raw material costs decrease by 22%, but we also avoided the risk of production line shutdowns caused by import disruptions.”
From the tiny insulating layers of semiconductor chips to the brilliant display surfaces of OLED screens, magnesium carbonate for target materials, though not directly consumer-facing, plays a critical role “behind the scenes” of high-end manufacturing. Hebei Messi Biology Co., Ltd., through technological innovation, has achieved breakthroughs in the purity, customization, and supply stability of domestically produced magnesium carbonate. This has not only broken the reliance on imports but also helped China’s target material industry move toward “high-end and localization,” injecting “Chinese Magnesium Power” into the stability and upgrade of the global electronic manufacturing supply chain.
