1. Product name: Molybdenum crucible liner

Since the melting point of molybdenum is as high as 2610 °C, molybdenum crucible liners 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.  Especially for the sapphire single crystal growth furnace, the molybdenum crucible liners with high purity, high density, no internal cracks, accurate size, smooth inner and outer walls, etc.

2. Description:

molybdenum crucible liner is recommended for Au, HfO2, In, MgF2, SiO2, Ag, Ta2O5, TiO2, TiO, and Zn.

All wall angles are 15 deg.

3. Specifications: 

4. Molybdenum crucible liner production process:

Molybdenum powder - isostatic pressing - intermediate frequency furnace sintering - molybdenum bar blank - high temperature forging - wool bar - turning grinding - polishing bar - wire cutting blanking - CNC machining - polishing - Ultrasonic cleaning - oven drying - inspection - vacuuming - packing

5. Features:

 ● High temperature resistance

 ● Corrosion resistance

 ●  High thermal conductivity

 ● Small thermal expansion coefficient

 ● High hardenability

6. PVD coating technology is divided into：

1）Vacuum Ion Coating(Vacuum ion coating machine);

2）Vacuum sputtering coating(Vacuum sputtering coating machine);

3）Vacuum evaporation coating(Vacuum evaporation coating machine).

Note： Often said PVD coating is vacuum ion coating, PVD coating machine refers to vacuum ion coating machine.

7.  Our company and factory

Baoji Magotan Nonferrous Metals Co., Ltd has complete physical property testing equipment, which can test the parameters such as density, hardness, surface roughness, grain size, and tensile strength of materials. For crucible products, products with hidden defects such as pores, slag inclusions, and cracks can be prevented from leaving the factory.

8. Molybdenum Crucible Liner Packing

The molybdenum crucible liner will be packed in a wooden case supported with soft materials to ensure that the products will not shift inside the cases.
