We have the exclusive patent products, research and produce the semiconductor key equipments. The outstanding advantage of its production is to take some techniques such as the plc auto-controlling system, independent innovating hot zone, magnetism liquid seal, power factor compensation and harmonic wave restraining and so on, which realizes the constant temperature of the hot zone, meets steady, continuous, high-efficiency, auto-controlling, non-dislocation and low oxygen and carbon requirements for dia.6inch--dia.8inch single silicon ingot. The products are high-efficiency, economize on energy, environmental protection and automatization , has the perfect foreground.

Our campany supply high quality quartz cruicble for monocrystalline production industry, now our crucible including 16" 18" 20" and 22" in diameter, and also can make by your drawing.
The raw material of crucible used is high purity quartz sands come from usa unimin company. Our crucible have virtues as follows:
Good thermal stability, can work continuously in long time.
Stable performance easy to control cz process.
During the whole process of cz, no soften, no crack and no bubble.
High price-performance-ratio.
Advanced quality control system is through the whole production process, easy to track the original quality data.
Strictly following the cleaning, drying and packing procedure, guarantee high purity and no pollution.
Vacuum technology .
Guarantee the whole cz process low oxygen, low defect and high ratio quality product.
No brown ring, very high dislocation ratio.
Alkali metal can not diffuse towards inside, reduce the impurity density.
Excellent anti-crystallization capacity.
Strict management and professional purity workshop
