Graphite crucible

Core application areas and sub-scenarios ‌

Metal smelting and casting ‌

Non-ferrous metal smelting ‌ : For the high-temperature smelting of copper, aluminium, zinc, lead and their alloys, especially suitable for the smelting requirements of small and medium-sized foundries and laboratories. ‌ ‌

Purification of precious metals ‌ : In the refining process of gold, silver, platinum, etc., it can withstand high temperatures and avoid metal contamination. ‌ ‌

Rare earth metal processing ‌ : In the smelting of rare earth elements (requires > It shows excellent performance at a high temperature of 1600℃. ‌ ‌

emiconductor and photovoltaic industry ‌

Monocrystalline silicon growth ‌ : used in the czochralsis process to hold molten silicon liquid with extremely high purity requirements (such as polycrystalline silicon for solar cells). ‌ ‌

Compound semiconductor synthesis ‌ : such as gallium arsenide (GaAs), silicon carbide (SiC) preparation, avoiding contamination by metal impurities. ‌ ‌

Chemical Engineering and Materials Synthesis ‌

Treatment of corrosive substances ‌ : Resistant to strong acids, strong alkalis or molten salts (such as fluorides), replacing traditional metal containers. ‌ ‌

Synthesis of nanomaterials ‌ : As a high-temperature reaction vessel in chemical vapor deposition (CVD) to control the synthesis conditions of graphene, carbon nanotubes, etc. ‌ ‌

New energy and special processes ‌

Lithium battery material production ‌ : High-temperature treatment of precursors for synthetic cathode materials (such as ternary material LiNiCoMnO₂). ‌ ‌

Additionally, graphite crucibles are one of the sources of graphite powder and crushed graphite

High temperature coating process ‌ : Plasma spraying filled with molten spray materials such as alumina. ‌ ‌
