product description99% alumina ceramics, also known as high-alumina ceramic balls, are used in high-temperature, high-resistance, clean, chemical and physical environments due to the aluminum content as high as 99%. High-purity alumina is a good material for the production of durable Grind parts.Features1. High strength, strong impact resistance, can be used in stirring mills, peeling machines, sand mills, ball mills, etc. 2. High wear resistance, the wear degree is only 1/3-1/10/T848.1-1999) value of the standard (JC). 3. Especially suitable for ultra-fine grinding and dispersion of Al2O3.
