In cutting-edge fields such as aerospace, precision manufacturing, and high-end equipment, a seemingly ordinary white powder is playing a key role—magnesium oxide. As an inorganic compound with excellent performance, magnesium oxide demonstrates diverse value in the preparation of high-end ceramic materials due to its high-temperature resistance, chemical stability, and strong controllability. The technological breakthroughs of Messi Biology have further unleashed the application potential of this material.
Magnesium oxide foam ceramic filters are the “gatekeepers” for the purification of alloy liquids. Traditional filters struggle to be compatible with the filtration of magnesium alloys and high-temperature alloys containing active elements, as they easily react and lead to purification failure. However, filters made from high-purity magnesium oxide have successfully solved this problem with their excellent chemical inertness, ensuring the purity of high-end alloy materials. The magnesium oxide produced by Hebei Messi Biology has a purity of up to 99.9%, with impurity content below 0.01%. Through advanced crystal growth control technology, the pore structure of the filters is more uniform, and the filtration efficiency is increased by 20% compared to the industry average, making it a preferred raw material for aerospace alloy smelting.
In the field of precision casting, magnesium oxide ceramic cores are hailed as “shaping masters.” They can maintain stability in high-temperature environments above 1600°C without reacting with the poured metal. The surface roughness of the casting can be controlled within 10μm, perfectly solving the pain points of silicon-based cores, which are prone to porosity and sand adhesion. Even more commendable is its excellent solubility; it can be quickly dissolved in weak acids, making the core removal process environmentally friendly and efficient. This is attributed to the process advantages of Hebei Messi Biology. The company uses a hydromagnesite method for preparation, creating a unique hexagonal lamellar crystal structure that combines high strength with good solubility. It does not deform or break during molding and handling, and its dimensional accuracy reaches the micron level.
Magnesium oxide’s “cross-disciplinary” capabilities in the field of functional ceramics are equally outstanding. Fused ceramic particles prepared by compounding it with alumina have become a core material in the abrasives industry due to their excellent hardness. When paired with rare earth oxides as a sintering aid, it can efficiently manufacture silicon nitride ceramic products, including cutting tools, sealing rings, and various other high-temperature and wear-resistant components. Furthermore, high-toughness zirconia ceramics made with high-purity magnesium oxide as a composite stabilizer are an ideal choice for high-temperature engineering components. The magnesium oxide products from Hebei Messi Biology not only lead in purity but can also be customized in terms of particle size and surface characteristics according to downstream demand. The collaborative research and development mechanism established with downstream enterprises allows the material to be quickly adapted to the production needs of different ceramic products. Related products have already passed aerospace-grade material certification and are being used in a new generation of launch vehicle components.
From alloy purification to precision molding, and from abrasive manufacturing to high-temperature components, magnesium oxide is driving the upgrading of high-end manufacturing with its diverse applications. With its core advantages in purity control, process innovation, and customized services, Hebei Messi Biology Co., Ltd. is transforming natural minerals into high-end material solutions. The industry standards it has participated in formulating have further established the global voice of China’s magnesium oxide industry. In the future, with the continuous iteration of technology, magnesium oxide will shine in more cutting-edge fields, and Hebei Messi Biology Co., Ltd. will continue to lead the industry from “quantitative accumulation” to a “qualitative leap” with the power of innovation.
