bubble alumina brick alumina refractory bubble products thermal insulation filling material Product name:alumina bubble Specification:0.2-1mm Properties of alumina hollow spheres : 1, the use of high temperature : the use of temperature up to 1750 degrees or more, good thermal stability. The change rate of reburning line is small and the service life is longer. 2.Saving energy : alumina hollow spheres have good thermal insulation properties, low thermal conductivity, can play

white hollow sphere new style high temperature thermal insulation heat insulation filler Product name:alumina bubble Specification:1-2mm Aluminum oxide hollow ball is a lightweight thermal insulation refractory material made by blowing out aluminum oxide after high-temperature melting in an electric arc furnace. Its characteristics are light weight, closed cell, and high temperature resistance, making it an ideal insulation filling material for high-temperature kilns, a high
