Product Description:
CBSP-XR3015@30 alumina ceramic balls are high-performance ceramic grinding media and fillers made from high-purity alumina as the main raw material, through precise formulation, isostatic pressing and high-temperature sintering. They have excellent properties such as high hardness, wear resistance, corrosion resistance, and high temperature resistance. They are widely used in mining, building materials, chemicals, electronic materials, environmental protection and other industries, and are an ideal substitute for traditional steel balls and ordinary ceramic ball.
Product Features:
·High hardness: Mohs hardness reaches 9, second only to diamond, with excellent wear resistance.
·High temperature resistance: It can work below 1600℃ for a long time, with good high temperature stability.
·Corrosion resistance: It can resist acid, alkali and organic solvent erosion, and is suitable for chemical environment.
·Low density: It is lighter than metal balls and reduces equipment energy consumption.
·Insulation: It is non-conductive and suitable for electronics and power industries.
