Summary:
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.
Product features:
- High purity
- High mechanical strength
- Low thermal conductivity
- Good stability
- Mainly apply to the insulation layer of coal-water slurry gasifier
- Excellent thermal insulation
- Long service life
- High compressive strength
- Competitive price
Range of application:
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.
