Parameters of Graphite Crucible for Metal MeltingSpouted Crucible Silicon Carbide Graphite Crucible
Thegraphite crucible parameter refers to the specific temperature range where the graphite solidifies, and it can vary depending on the chemical composition of the rock used as a fuel source. Generally, graphites require a high temperature above 2500°C to solidify at a certain pressure, typically around 46 MPa.
Some common parameters for graphite crucibles include:
1. Temperature: The most important parameter is the temperature at which the graphite solidifies, typically between 2500°C and 3500°C.
2. Pressure: The highest pressure is around 7 MPa, while lower pressures will allow for less solids to form in the crucible.
3. Melting rate: A higher melting rate indicates a faster solidification process.
4. Material composition: Different materials have different melting temperatures and melting rates, so the choice of material should be based on factors such as the desired type of raw material, the desired melting speed, and the durability requirements.
5. origin: Different materials have different melting temperatures and melting rates than those from domestic sources.
Overall, the key factor to consider when choosing a graphite crucible is to select a material that meets the required specifications and has the desired melting temperature and melting rate for your intended application.
