Quartz Crucible Silica Crucible Quartz Melting Crucible

Zhengzhou STA factory supply top quality quartz crucible with large size
Product Description
Quartz crucible of arc melting used for semiconductor industry is the essential basic material for pulling monocrystalline silicon and developing L S I circuit. It has the advantages of high purity, high temperature resistance with big size, good thermal insulation, economization on energy, quality stability etc.We also can produce various specifications oftransparent and translucent crucibles. Crucibles can be produced according to the standard or produced on customer's
Description of quartz crucible
♥ 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
