Customized graphite crucible
A graphite crucible is a high-temperature container, usually made of high-purity graphite material, used for material storage, transportation, and reaction vessels in processes such as melting or solid-state reactions at high temperatures. Graphite crucibles have excellent high-temperature resistance, oxidation resistance, and corrosion resistance, especially suitable for chemical reactions and metal melting applications at high temperatures.
Graphite crucibles are mainly divided into two types: one is machine made graphite crucibles, and the other is isostatic pressure graphite crucibles. Machine-made graphite crucibles are made from graphite powder processed through processes such as pressing, forming, and drying, and are commonly used in fields such as non-ferrous metal melting, refining, and chemical analysis; The isostatic pressing graphite crucible forms a certain structure of graphite material through a high pressure bonding agent, and its structural uniformity and density are also higher, making it suitable for high-end applications such as the production of photovoltaic cell materials.
Graphite crucibles have the following main characteristics:
1. High temperature resistance: Graphite crucibles can resist the erosion of high-temperature molten metals and various acids and alkalis, while also possessing excellent thermal conductivity and conductivity.
2. Corrosion resistance: The graphite crucible has excellent corrosion resistance and can be used in various acids, alkalis, salts, and other media, and can withstand the erosion of chemicals, organic matter, or gases.
3. High precision processing: The graphite crucible processing technology is mature and can achieve high-precision internal and external shape processing. At the same time, the control of the internal material composition of the crucible is relatively simple.
In summary, graphite crucibles are widely used in fields such as high-temperature melting, chemical reactions, and material preparation. Their clean, pollution-free, and long service life characteristics make them particularly popular in scientific research and industrial applications.
