Characteristic:
High temperature strength - reliable use in air even at temperatures over 1600°C (up to 2000°C under inert gas and vacuum).
Hardness - SSiC is second only to diamond and cubic boron nitride as a high performance material.
Wear Resistance - Ultra-high hardness and density make it ideal for parts that are often subject to high wear.
Thermal Shock Resistance - Excellent thermal shock resistance due to high thermal conductivity and low coefficient of thermal expansion, better performance in rapid thermal cycling compared to other refractories.
Corrosion, Oxidation and Erosion Resistance - High density, low porosity and chemical inertness make it perform well in high temperature gas and liquid environments, oxidizing and corrosive gases, and strong acids and bases, even in Even at ultra-high temperatures.
High thermal conductivity - has the equivalent thermal conductivity of graphite material, which is 5 times that of alumina.
