Our single crystal fused alumina is made by a new developed technology. Its colour is blue instead of yellow as of the ol tech.

The single crystal alumina oxide is made by a new developed technology, with no air contamination. The products colour is light blue. The single crystal is is 50% more than that made by the previous production methos, and the toughness is 25% higher than that of the old one. It is protected by Chinese patent.
