Silicon carbide (SiC) ceramic crucible is made of high purity silicon carbide powder, its material composition is nearly pure silicon carbide (SiC), silicon carbide purity content of up to 99.7%+, with non-porous and impermeable characteristics, can accommodate high purity metal without being polluted. High thermal conductivity enables efficient processing, while excellent thermal shock resistance enables fast heating and cooling cycles without cracking or damage.
Silicon carbide ceramic crucibles have a unique set of material properties that make them the product of choice for demanding high temperature applications requiring stable, reliable and reusable sealing materials. Their suitability for casting, melting and crystal growth processes is unmatched.
Excellent hardness and wear resistance: With a Mohs hardness of 9.5, silicon carbide is one of the hardest materials known, surpassing even corundum and second only to diamond, cubic boron nitride and boron carbide. This extraordinary hardness translates into excellent wear resistance, making sic crucible ideal for withstanding the wear and erosion caused by molten metal.
Excellent thermal conductivity: Silicon carbide has an impressive 120 W/m•K thermal conductivity, even exceeding many metals. This excellent property enables the silicon carbide crucible to efficiently transfer heat, ensuring uniform melting and preventing local overheating.
High temperature stability: Silicon carbide exhibits excellent stability at high temperatures, maintaining its structural integrity and mechanical strength even under extreme heat conditions. This characteristic makes sic crucible suitable for applications requiring high temperature performance, such as melting aluminum, copper and other metals.
Excellent corrosion resistance: Silicon carbide has strong chemical resistance, so that it is not corroded by molten metal and its related fluxes. This feature ensures that the silicon carbide crucible maintains its integrity and performance during long-term use
