Audited Supplier Introduce of Alumina Hollow Ball Brick
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.
Features:
1.Low thermal conductivity, good thermal insulation effect;
2.Refractoriness is as high as 1750 ºC
3.Mullite Insulating bricks can save you heat and a lot of money.
4.Mullite insulation brick can lighten the weight.
