Classification and Introduction of Graphite Crucible
Created on 2024.05.27
Pure graphite crucible is inexpensive, versatile, and has a high carbon content and melting point, making it suitable for use in laboratories and industrial production. However, pure graphite crucibles have relatively poor mechanical properties and are prone to cracking due to large temperature differences. Therefore, it is important to carefully control the temperature during application to prevent rapid heating and cooling.
Silicon carbide graphite crucible is a high-performance ceramic graphite material with a low thermal expansion coefficient, high strength, high temperature resistance, oxidation resistance, and good chemical stability. It does not expand or deform at high temperatures, and has excellent corrosion resistance. Therefore, it is widely used in special thermal analysis and molten material testing.
Silicon carbide crucible is a new type of material with superior physical properties and chemical stability compared to silicon carbide graphite crucible. Silica nitride graphite crucible has the advantages of high temperature strength, high oxidation resistance, and corrosion resistance, making it suitable for use at higher temperatures and in acidic and alkaline environments. As a result, silica nitride graphite crucible has been widely used in high-temperature industrial fields such as steel and aluminum alloy.
The molded graphite crucible is made of high purity natural graphite and other additives, has extremely high fire resistance and low coefficient of thermal expansion, and can withstand corrosion under high temperature and pressure. Molded graphite crucible has been widely used in the electronics industry, solar cell industry, rail transit industry and other fields, but also suitable for a variety of high temperature test and production applications.
In general, different types of graphite crucibles have their own characteristics and application advantages in different application fields. When using graphite crucibles, it is necessary to select the appropriate material and type of graphite crucible according to the actual needs and specific application scenarios.
