White Aluminum OXIDE for Refractory Materials

we are a professional factory of white/brown fused alumina

we have been export for 10years

we offer free samples,good aftersales service

our products hot in Europe,Australia,US

 

White Fused alumina,was made from the high quality alumina by melting above 

2000 in the electric arc furnace and cooling.

 It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has 

the advantage of high bulk density and low porosity and the volume stability and 

thermal shock resistance can be improved.

5. The tooth model of clean sand;

6. Precision sand casting;

7. High refractory and other ceramic additives

 

White fused alumina size w1-w63 

Suitable for various precision instrument parts polishing, ultra-precision machine tool spindle grinding and polishing crystal, super oil stone manufacturing, 

ball polishing, etc. Widely used in the polishing of electronics, optical instruments, glasses, 

bearing, quarts crystal, and advanced refractory material.

 

Details:

1. High hardness, particle density, good single particle roundness;

2. White, no impurities, ensuring wear-resistant layer or wear on paper color and transparency;

3. Particle size distribution concentrated, single single-particle form, minimum amount with maximum effect

Selected from the melting temperature by more than 2000 degrees well made of quality white 

fused alumina as raw material, its chemical stability and acid and alkali effect does not occur,
