high purity alumina crystal

High purity alumina can be widely used in high voltage sodium

lamps tube, ruby, sapphire, LED crystal growth, ceramic substrate, catalyzer carrier, fluorescent materials and abrasive materials.

The purity can reach 99.995%-99.999%.Partical size ranges in 0.1um-10um.The main impurity content, like fe, si, ca and so on, is very low.

The quality obtain the consistent approval by the International

market, like Russia.American, Europea.Korea, Japan, China and so on.
