Quartz crucible is an essential component in the process of the mono-crystal silicon pulling whose performance has great influence on the crystallization rate. This is because when divirtrification occurred on the inner surface, the crystallography may fall off then adhere to the single silicon,thus to reduce the crystallization rate. AQMN's crucibles aren't easily to form devitrification and have the following 2 characteristics:
1. Less bubble in the transparent layer
2. Inner surface high purification
Quartz crucibles produced by our company, there are no bubbles in the transparent layer. The current main type all adopt special process technology, then make the series can restrain bubble expansion in the back-up layer and promote the service life under high temperature drastically.
