Quartz Crucible
Quartz Crucibles
Quartz crucible with high purity and strong thermo-stability is an essential component in the process of the mono-crystal silicon pulling. The performance of the quartz crucible has great influence on the crystallization rate. Ferrotec (China) crucible division has been around how to improve the crystallization rate by continuous technological innovation and has made great breakthrough. In order to satisfy diversity production needs of the customers, AQMN had developed 4 series quartz crucible to reply different crystal pulling technology. For the current diameter size, AQMN can coverage 14 to 32 inch and has the technical ability to customize larger size according to the customer’s requirement. On the supporting process, we took 3 years to develop a fully automatic line to ensure the quality stable.
