Description
Alumina hollow insulation brick, also named Alumina bubble brick, is based on the alumina hollow ball and alumina powder as the main raw material, mixing with other binders by sintering at 1750 degrees high temperature. It is a kind of new type high temperature thermal insulation materials, max working temperature can reach to 1800℃. It has longer service life and can be energy saving. Alumina Bubble Brick is a kind of very important refractory material for resisting high temperature and special demands of positions for furnace and kiln, which is mostly used as insulating brick for insulation layer of furnace and kiln, and also can be used for service linings in manufacturing high-purity quartz for the electronics industry such as ceramic tile linings in gas turbines and backup linings in reactors.
Characters:
