Alumina Bubble Brick Description

Alumina bubble fire brick is a new type high temperature heating insulation materials and made of industrial alumina in the electrical furnace through smelting and blowing. alumina bubble refractory brick crystal form is a-Al2O3 microcrystal and main body is alumina bubble which can be made to be all kinds of products with various shapes for serving the highest temperature of 1800℃ with high mechanical strength and low bulk density.

Properties of Alumina Bubble Brick

Light weight,
Saving energy,
Lower construction cost,
High temperature resistance,
Low reheating linear change,
Good thermal shock resistance.

Manufacturing Process of Alumina Bubble Brick

Aluminium bubblle firebrick adopt alumina bubble ball as the main raw materials, high performance ultrafine powder as the annexing agent and organic substance as the binding agent through molding and drying, and then are fired in the high temperature shuttle kiln.

Advantage of Alumina Bubble Brick

Aluminium bubblle fire brick has the features of heat insulation and low thermal conductivity, which can result the great heat insulating effect, reduce heat waste and improve thermal efficiency. using aluminium bubblle refractory brick can save energy high up to 30%. and alumina bubble block’ service temperature is high up to 1750 ℃. the thermal stability is good and the reheating linear change rate is low, aluminium bubble block can results the long service life.
