Magnesium oxide (chemical formula MgO) is a high-melting-point, non-toxic, white powdered inorganic compound. As an alkaline oxide, it possesses excellent fire resistance, chemical stability, and adsorption properties. It is widely used in industrial refractory materials, pharmaceutical antacids, environmental pollution control, food additives, and new energy materials.

Magnesium oxide used in glass fiber production must possess specific characteristics that are compatible with the glass melting process and fiber performance requirements. These characteristics can be summarized as follows:
First, high purity and low impurities. Typically, the magnesium oxide content is required to be ≥95%, and the levels of impurities such as silicon, iron, calcium, and chlorine are strictly controlled (e.g., iron ≤ 0.1%, calcium ≤ 0.5%). This prevents impurities from forming bubbles or stones in the molten glass, or affecting the fiber's transparency and mechanical properties, ensuring defect-free finished glass fibers.
Second, appropriate activity and particle size are required. Magnesium oxide powders with medium-to-low activity (activity value 40-60s) and fine particle size (average particle size 1-5μm) are often used. This allows for uniform mixing with glass raw materials such as quartz sand and soda ash, rapid dissolution during high-temperature melting, and participation in the formation of the glass network structure, avoiding uneven composition due to incomplete dissolution.
Third, stable chemical properties are required, with good thermal stability (high temperature resistance). The powder must be heat-resistant (above 2800°C) and non-decomposition and non-volatilization in the high-temperature environment of glass melting (1500-1600°C). It must also stably react with elements such as silicon and aluminum to form a dense glass structure. Its alkalinity must also be mild and controllable to avoid excessive corrosion of the furnace's refractory materials.
Fourth, it must have low hygroscopicity and fluidity. The finished product must be dried to a moisture content of ≤0.5% to prevent moisture absorption and agglomeration during storage or mixing, which could affect the dispersion of the raw materials. The powder must also exhibit good fluidity to accommodate the continuous feeding and precise metering requirements of glass production, ensuring a stable and efficient production process.
