Product description
Alumina hollow ball is a new type of high-temperature insulation material, it is made of Al2O3 with more than 98%, then melting in a three-phase arc furnace, to melt the liquid alumina by compressed air. Sphere is crystallized as a-Al2O3 micro-crystals. Alumina hollow can be made into a variety of shapes, the maximum temperature is 1800 C, with high mechanical strength, it is several times for other general light productions, while the bulk density is only half of corundum.
Available Size
1. Mixed ball: 0.2-5mm
2. Graded ball:0.2-1mm,1-2mm,2-3mm,3-5mm
Models can be customized according to customer needs
Applications
1.Alumina hollow ball is a high temperature/energy efficient light refractory materials, and very stable. Especially in 1800 ° C high temperature furnaces.
2.Can be used to do high temperature/ultra-high temperature insulation filler, high temperature refractory concrete lightweight aggregate, high temperature castable etc..
3.Can be used for high temperature energy saving (> 30%) down flame kiln, shuttle kiln, molybdenum furnace, tungsten furnace, induction furnace, nitriding furnace.
4.Reduce the weight of the furnace, transform the structure, save material, save energy, will achieve significant results.
5.Petrochemical industry gasifier/carbon black industrial reactor/metallurgical industry induction furnace/other high temperature/ultra-high temperature furnace.
