Silicon Carbide Pot
Silicon Carbide Products SeriesSilicon carbide pots and tanks (reaction bonded SiSiC / recrystallized RSiC) are produced from high-purity silicon carbide fine powder via precision slip casting and high-temperature sintering. They deliver high thermal conductivity, extreme acid/alkali corrosion resistance, high strength, and dimensional stability.

Material Introduction
Silicon Carbide (SiC) Pots and Tanks are high-performance structural ceramic vessels. With a Mohs hardness of 9.2~9.5 (second only to diamond and boron carbide), they possess exceptional wear resistance and chemical inertness.
In hot concentrated acids, alkalis, and molten salt environments, SiC exhibits extraordinary resistance against corrosive attack. Moreover, its thermal conductivity is 5 to 10 times higher than conventional oxide refractories, facilitating rapid, uniform heat exchange and shortening reaction/crystallization cycles.
Product Features
- Outstanding Corrosion Resistance: Withstands sulfuric, hydrochloric, nitric acid, strong alkalis, and molten salts without contamination.
- High Thermal Conductivity & Uniform Heat Transfer: Eliminates hot spots and optimizes temperature uniformity.
- Superior Thermal Shock Resistance: Low thermal expansion coefficient prevents cracking under severe temperature cycling.
- High-Temperature High-Strength & Anti-Creep: Retains high mechanical strength above 1400°C, with strong creep resistance that helps reduce the risk of deformation and leakage.
- Custom Sizes & Shapes: Available in cylindrical, flanged, flat-bottom, or round-bottom configurations.
