Alumina Bubble 0.5-1mm
Alumina Bubble 0.5-1mm is made of high Al2O3 purity fused alumina. The hollow bubble shape gets from the blowing process after fusing. The main crystal structure of bubble alumina is α-Al2O3. With a good control system, the ball shape rate from us is up to 90%. It is a kind of light refractory material with excellent high-temperature resistance and energy saving. It is very stable to use in various environments. Especially it is used in the high-temperature kiln at 1800℃.

Alumina Bubble 0.5-1mm Properties:
Bubble alumina is a kind of hollow alumina bull & hollow alumina ball shape. Related refractory product made from it gets a high-temperature resistance, high thermal stability. It also gets high mechanical strength which is several times that of ordinary lightweight refractory products, and the bulk density is only half of that of other corundum products.
Bubble alumina can be used as high-temperature thermal insulation fillers, high-temperature refractory concrete lightweight aggregates, high refractory castables, etc. Bull alumina insulation fire brick made from hollow alumina can be used for high-temperature energy-saving (Bubble alumina content >30%) kiln furniture including inverted flame furnaces, shuttle furnaces, molybdenum wire furnaces, tungsten bar furnaces, induction furnaces, nitriding furnaces, etc.
Adopting bubble alumina, always get excellent performance such as reduce the weight of the furnace body, rebuild kiln structure, save materials consumption and save energy. Bubble alumina has been widely used in high-temperature furnaces such as petrochemical industrial gasifiers, carbon black industrial reaction furnaces, metallurgical induction furnaces, etc., All applications above with bubble alumina are turned to be successful from users.
Also, the alumina hollow ball can be used as a filling material for the diamond grinding wheel to play a role in making pores. The grinding wheel adding bubble alumina can quickly take away the heat generated by the grinding work due to the existence of pores during the grinding process. It can improve the sharpness, and reduce burning on the surface of the workpiece.
Alumina Bubble 0.5-1mm Application:
1. High temperature and ultra-high temperature insulation filler
2. Pore making material of diamond wheel to avoid the burning of the grinding wheel
3. Lightweight aggregates of high refractory concrete
4. High refractory castable
5. Refractory bricks & insulation fire bricks
6. Kiln future material, high-temperature furnace lining material
