Microcrystalline alumina spheres

2017-08-21

Features: rounded appearance, high hardness, density, acid and alkali resistance, corrosion, low loss, complete specifications and strong applicability.

Uses: mainly used in non-metallic mineral products, powder, ceramics, superfine powder processing, coating, paint, medicine, chemical, printing ink, refractory materials and other fine grinding materials for grinding media.

Isostatic pressing molding: the specification is Phi 30 - 120mm

Roll forming: specification: Phi 1 - 40mm
