Tungsten Crucible For Quartz Glass Melting Furnace
1. Tungsten Crucible For Quartz Glass Melting Furnace Description:
High thermal conductivity, a low thermal expansion coefficient, a high melting and boiling point, good high temperature strength, wear and corrosion resistance, and good hardenability are all properties of tungsten.Therefore, tungsten crucibles are widely used in core containers in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass melting furnaces, and rare earth smelting furnaces. The working temperature environment used is generally above 2000 °C. Especially for sapphire single crystal growth furnaces, tungsten crucibles with high purity, high density, no internal cracks, accurate size, smooth inner and outer walls, etc. Decrystalline sticking to the pan and service life play a key role.
2. Dimensions of the tungsten crucible used in the quartz glass melting furnace:
| Purity | Diameter(mm) | Wall thickness(mm) | Height(mm) |
| W≥99.95% | 30-50 | 2-10 | ≤1000 |
| 50-100 | 3-15 | ||
| 100-150 | 3-15 | ||
| 150-200 | 5-20 | ||
| 200-300 | 8-20 | ||
| 300-400 | 8-30 | ||
| 400-450 | 8-30 | ||
| 450-500 | 8-30 |
Tungsten crucibles of various sizes can be customized according to customer requirements.
3. The Tungsten Crucible For Quartz Glass Melting Furnace Manufacturing Process:
Tungsten powder -- sieving -- batching -- isostatic pressing -- rough blank turning processing -- intermediate frequency sintering -- fine turning processing -- finished product inspection -- packaging.
