Uses of high temperature melting, vacuum arc technology, thermal stability, can continuously work long hours under high temperature
High temperature did not form cristobalite particles, easy-to-pull crystal control, stable performance
Crystal pulling process, non-edge softening and collapse of phenomenon, no bubbling hot cracking phenomenon
Ensure that process of pulling crystal oxygen content and micro-defects on high rate of genuine
Does not produce brown ring with high ratio of dislocation-free
Alkali metal to internal problem of proliferation, reducing impurity concentration in inner crucible
Nice anti-crystallization properties of performance:
Unique combination of properties, excellent resistant to thermal vibration performance, high deformation temperature, softening temperature, low thermal conductivity, low dielectric loss and UV spectral range of optical through ability
Can be divided into thermal and pure performance
