Black SiC F150 for Silicon carbide ceramic sealing ring

Product introduction of Black SiC F150 for Silicon carbide ceramic sealing ring

Black SiC F150 for Silicon carbide ceramic sealing ring is a fine‑grade black SiC granular raw material with stable particle size distribution and low impurity content. It boasts high hardness, outstanding thermal conductivity and exceptional oxidation resistance at high temperatures. When formulated for sintered silicon carbide ceramics, this grade helps form a dense, uniform ceramic microstructure after firing. The finished sealing ring gains superior wear resistance, low friction coefficient and excellent corrosion‑proof performance against most chemicals. It is a reliable key filler for manufacturing high‑precision mechanical SiC sealing rings used in pumps, valves and industrial sealing equipment.

Product Feature of Black SiC F150 for Silicon carbide ceramic sealing ring

• High purity, the purity of black silicon carbide after pickling can reach 99%. The production process of black silicon carbide powder is hydraulic classification, with less impurities and high purity.
• Superior oxidation resistance and chemical stability: when heated to 1000 ℃ in the air, silicon carbide only oxidizes on the surface, forming a layer of silicon dioxide film, which can protect silicon carbide material from oxidation. When heated to above 1627 ℃, the oxidation resistance of silicon carbide will decline rapidly.
• High hardness: Mohs hardness of black silicon carbide is 9.2-9.3, slightly lower than that of green silicon carbide.
• The toughness of black silicon carbide is higher than that of green silicon carbide.
• The packing density is high, and the black silicon carbide particles produced by the shaping process are more rounded.
• It has high cleanliness and is washed twice after crushing, reducing the dust in the abrasive.
