Alumina Refractory Bubble Insulating Brick

This series of products are sintered mainly with high-purity alumina refractory bubble. Low bulk density, low thermal conductivity, excellent compression resistance, outstanding high temperature resistance, superior slay resisance and corrosion resistance. They are ideal as inner linings of the furnaces and kilns, which work in a high temperatuer environment, such as synthtic ammonia liquefaction furnace, ethylene gas making furnace, etc. Better to use below 1800C.
