Product Code : CE-RSiC-NN-TP
Recrystallized Silicon Carbide SiC are advanced engineered ceramics which can be cast or extruded into a wide variety of flat and elongated shapes, such as plates, tubes or beams. The material is consolidated at temperatures above 2000°C (3992°F) through a sublimation and condensation process of fine silicon carbide particles. Thanks to the high material purity (SiC > 99.5%), it benefits from the exceptional inherent thermal, chemical and mechanical properties of silicon carbide.
ATT produces Recrystallized Silicon Carbide RSiC 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.
