Alumina Bubble Brick Introduction
Alumina Bubble 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 Bricks' crystal form is a-Al2O3 microcrystal and main body is alumina bubble that can be made to be all kinds of products with various shapes for serving the highest temperature of 1800ºC with high mechanical strength and low bulk density.
Alumina Bubble Brick Features
1. the use of high temperature, reaching more than 1750 degrees, the thermal stability is good.
2. small size, optimize the structure, reduce the weight of the furnace body.
3. the corrosion resistance of slag is good, and the usage period is long.
4. low thermal conductivity, good thermal insulation effect.
