Alumina Grinding Media
Product Details
Product Introduction:
Kingda polished alumina ceramic jars are used whenever small quantity of samples needed to be grinded. Each jar set includes grinding jar, lid, rubber sealing gasket and different sizes of mixed alumina ceramic grinding balls. It is best container for grinding rare earth materials, precious metals, medium and low ceramic capacitors, NTC, PTC piezoelectric ceramic and lithium cobalt oxide, lithium manganese oxide powder.
