new product alumina hollow ball

Introduction of alumina hollow ball:

Alumina hollow sphere is a new type of lightweight and heat-resistant and refractory material. It uses alumina with more than 98% content into three phase electric arc furnace to melt, and compressed air to melt molten alumina into hollow spheres, that is, alumina hollow spheres.

Classification of alumina hollow spheres:

alumina hollow sphere/ball 0.2-1mm

alumina hollow sphere/ball 1-2mm

alumina hollow sphere/ball 2-3mm

alumina hollow sphere/ball 3-5mm
