Product feature and application
High purity alumina is the high-end product of aluminum industry, and it is also the main raw material of artificial sapphire. The new project makes up for the gap of rare earth high purity aluminum preparation technology in the world, and will also make the industrial chain of high purity aluminum and artificial sapphire complete connection.
High purity aluminum hydrolysis with a purity of more than 5N is the main raw material for sapphire single chip production of LED substrate. 90% of the world's LED enterprises use sapphire as the substrate material. With the continuous development of the LED industry and the popularity of smart terminals, the demand for sapphire continues to expand.
Product superiority
Good uniform particle size distribution and fluidity, strong strength, high mechanical strength, corrosion resistance, not easy to produce scratches, narrow particle size distribution, after grinding material surface quality is good, can throw bright luster.Strict product packaging, transportation process to ensure product quality, thoughtful after-sales service, to provide customers with high quality products.
