Protecting Tubes – Small Diameter Silicon Carbide
SA SiC is produced by pressureless sintering sub micron silicon carbide powder. The sintering process results in a self-bonded, fine grain SiC product which is highly resistant to corrosion, erosion, high temperature and thermal shock.
CORROSION RESISTANCE
SA SiC has superior corrosion resistance than alumina and other refractory materials in environments of hot gases and liquids, including strong acids and bases.
EROSION RESISTANCE
SA SiC is 50% harder than tungsten carbide. This extreme hardness combined with high purity and fine micro structure makes SA SiC resistant to erosion under abrasive conditions.
HIGH TEMPERATURE PROPERTIES
The single phase composition of SA SiC enables it to reliably perform in air up to temperatures of 1650°C (3000°F). It contains no free silicon which makes it highly chemical resistant in both oxidizing and reducing environments.
THERMAL SHOCK RESISTANCE
Because of its high thermal conductivity and low coefficient of thermal expansion, SA SiC is very resistant to thermal shock and thermal cycling as compared to other refractory materials.
