Graphite Crucible Liner

Advantages of graphite crucible liner

Excellent high-temperature thermal stability

You can use it stably for a long time in an ultra-high temperature inert environment above 2000°C.

Smooth and dense inner wall

Because of a high thermal reflectivity, it can effectively concentrate the heat in the furnace.

خواص كيميائية مستقرة

The graphite crucible liner will not react with silicon melt, precious metals, or ceramic raw materials.

Thin and regular structure

This makes it easy to disassemble, replace, and maintain, and it has high overall durability.

Excellent uniform heat conduction ability

It can make the internal heating of the crucible more balanced and avoid excessive local temperature differences.

Heat conduction balance

It can directly withstand the erosion of the materials and the high-temperature wear, which protects the outer main crucible body from damage.

Uses of graphite crucible liner

Semiconductor field

Crystal growth protection

Because it has high purity and no impurities are released, it can prevent impurities from contaminating the melt in the البوتقة body. At the same time, it ensures a stable and clean environment for crystal growth, which effectively improves the finished quality and yield of semiconductor wafers.

Photovoltaic energy field

Silicon material melting and ingot casting

You can use the graphite crucible liner in the processes of photovoltaic polycrystalline silicon ingot casting and silicon material purification. It is subjected to direct erosion by high-temperature silicon liquid, which protects the outer structure of the crucible, maintaining a stable temperature field environment. It can also optimize the crystallization quality of silicon materials, enhancing the photoelectric conversion performance of photovoltaic silicon wafers.

Precious metal metallurgy field

Rare metal melting

With the strong chemical stability, it does not react with the metal melt, which ensures the purity of precious metals. And it reduces raw material loss, and improves the recovery and purification efficiency of precious metals.

New materials field

Ceramic and powder sintering

You can use it in the high-purity ceramic powders and special carbon materials’ high-temperature synthesis melting. It can avoids oxidation and contamination of the powders, which ensures the purity, making the new materials meet the standards.

High-temperature experimentation field

Scientific research high-temperature melting

It can provide a stable, clean, and uniform-temperature high-temperature chamber environment, so it is suitable for various new material research and trial production scenarios.

Equipment operation and maintenance field

Crucible protection and cost reduction

You can replace the low-cost inner liner instead of replacing the expensive main crucible as a whole to significantly reduce the cost of equipment consumables. It can simplify the maintenance process, extending the overall service life of the high-temperature crucible equipment.
