The features of melting the fused silica crucible:
1.ultralow dilatation coefficient, high thermal stability, no
crack in 1000℃ water cooling
2. Long service life, especially suitable for quick heating and
cooling
3. Few impurity, high quality of firing rare earth.
4. Quick heat conduction, low energy consumption, reducing energy
consumption
5. Light weight and reducing labor intensity; smooth wall, coat
no powders and reduce rare earth polishing
6. Number of usage is more than 100 times
7. The product is used for polysilicon of solar energy
Because the high-purity Melted quart has the features of fine structure, low heat conductivity, small coefficient of thermal expansion that the manufactured goods has high dimensional accuracy, no deformation in high temperature, good thermal shock resistance, good electrical property and resistance of chemical attack. Therefore, it is widely used in glass deep processing industry, metallurgy industry, electronic industry, chemical industry, aeronautics and astronautics.
