1.Specification of Quartz crucible for for single crystal silicon

　　1. using IOTA-CG grade high purity quartz sand(SIO2≥99.99%)

　　2. coated inner layer with strict defect control(foreign inclusions, bubbles, bubble clusters, scratches/scuffs, structure faults, spikes, vapor clouds…)

　　3. high thermal performance(strong heat resistance, high transmission)

　　4.Can be made according to the requirement of our customers high purity crucible,the range of our products is from 18-24 inches.

　　We use high-temperature arc-melting and coating method.

　　To ensure the high purity of quartz crucible,Minde insists to use high purity raw material which is import from U.S and dose not add any domestic quartz sand.
