α-Alumina Products
α-alumina (commonly known as corundum) is the most stable phase of all alumina, with uniform particle size distribution, high purity and high dispersion. It has a low specific surface area, high temperature resistance, stable crystal phase and high hardness. It is widely used in the reinforcement and toughening of various plastics, rubbers, ceramics, refractory materials and other products, which can improve the fracture toughness and creep resistance of ceramics and the wear resistance of polymer materials products.
High-purity α-alumina is widely used in flame-retardant diaphragms, coated positive electrode materials and solid electrolyte materials due to its high temperature resistance, corrosion resistance and insulation properties. Alumina plays an important role in the field of lithium batteries. Our company has prepared a series of high-purity α-alumina products based on the boehmite process. The models and indicators are as follows:
