High pure fused silica crucible using temp: 1200-1450 C We can produce it according to your drawings

Quartz crucible Quartz crucible has the integrated performance which other materials dont have. There are excellent performance of resist thermal vibration, very high temperature of deformation and softening, very low performance of heat transmit and dielectric losing, the optical capacity of very wide UV spectra

(1) The heat capability

 The heat expansion coefficient of our quartz crucible is low, so the performance of resist thermal vibration is very fine. Crystallization is a process of separate out silicon dioxide crystal from the quartz crucible in high temperature, also is the most taboo of physical phenomena in crystal growth. Our company's innovation and unique manufacturing process would overcome the crystallization phenomenon in the process of crystal growth for enhancing the crystal-crystal rate and yield

 (2) Performance of High Purity

The high-purity quartz crucible has a great impact on physical parameters of the crystal and the life of tiny of non-equilibrium carrier. The inner transparent process and high-purity coating process of our crucible ensures users need of high purity crystal growth technology. All high standards of cleaning packaging and have no use for cleanout to user have won the praise of masses of customers, constant technological innovation and unique process has been awarded a high degree of trust from customers, high-quality after-sales service is our basic tenet
