silicon carbide crucibles

Silicon Carbide Crucible

The silicon carbide crucible boasts an array of remarkable properties such as high temperature resistance, excellent thermal shock stability, minimal expansion coefficient, resilience against strong acids and alkalis, resistance to spalling, good anti-powdering characteristics, and superior high-temperature creep resistance. Furthermore, its rapid heat conduction ensures uniform heating of the products being fired, effectively reducing energy consumption, accelerating the firing process, and enhancing production output. This crucible finds widespread application in the sintering of lithium-ion battery materials, electronic components, magnetic materials, highly corrosive substances, and various ceramic powders.

Properties of SiC Crucibles

⩠ Outstanding Thermal Conductivity

Its thermal conductivity far surpasses other corrosion-resistant materials, enabling the use of smaller heat exchange areas for the same heat transfer efficiency.

 

⩠ Remarkable Corrosion Resistance

Possesses exceptional corrosion, oxidation, and erosion resistance, enduring high concentrations of sulfuric acid, nitric acid, phosphoric acid, mixed acids, strong alkalis, and oxidizing agents, thus offering an excellent service life.

 

⩠ Superior Thermomechanical Properties

Boasts high strength and hardness, along with exceptional wear resistance and impermeability under extreme high temperatures and pressures. It allows media to pass through at high speeds and can operate normally at temperatures up to 1300℃.
