氧化铝空心球制品图
本制品采用纯氧化铝空心球，氧化铝微粉为主要原料，添加适量高温结合剂，经1750℃高温烧成。制品具有体积密度小、热容量小、强度高、封闭气孔多、抗剥落和热稳定性好等特点。用作高温窖炉保温材料和高温窖炉内衬。
Alumina Bubble Produvtis sintered at high temperature of 1750℃ and made maily feom pure Alumina Bubble,Alnmina micropowder definife high temprature cement. It has thecharacrers of low bulk density and thermal capacity,high strength, lots of invisible porosit, spalling resistance and good thermal steadiness. Lt is used as the high temperature insulaton material kikn inner liners.
