Calcined Alumina Powder

Product Detail

Calcined  Alumina powder for polishing: 

Using a unique production  process, the use of advanced production equipment at home and abroad, through  rigorous production processes made. The product has the following superior  performance:
 ? crystal phase  stability, high hardness, small particles and uniform distribution;
 ? grinding power,  polishing fast, bright light, the mirror effect is good;
 ? high grinding  efficiency, good polishing effect, grinding efficiency is much higher than that  of soft abrasive such as silica, the surface finish is better than that of  white corundum, strong cutting force, fast light, can throw a uniform and  bright
