Product Code : CE-SiSiC-NN-TP
Sintered Silicon Carbide SiSiC is produced at extremely high temperatures (~2,000°C) in inert atmospheres using a range of forming methodologies, including dry-pressing and extrusion. Reaction bonded, or siliconized, silicon carbide is formed using a porous carbon feedstock and molten silicon via additive forming, casting or extrusion. Each of these fully-densified silicon carbide ceramics achieves exceptional chemical and mechanical properties in extreme end-use temperatures exceeding 1,400°C (2,552°F).
ATT produces Sintered Silicon Carbide SiSiC tubes, reaction bonded SiC tubes, and recrystallized SiC tubes. tubes, Our recrystallized SiC products have high purity, while our reaction bonded and sintered silicon carbide balls have high mechanical strength. Our silicon carbide tube possesses good wearability, a low thermal expansion coefficient, extreme corrosion resistance, high hardness, and self-lubricating properties.
