Sintered silicon carbide seal faces is our feature product.
Mission Ceramic supply high quality precision silicon carbide ceramic part. Like ring, tube, bushing, rod, disc, and other parts as you need. SiC ring is our main product.
According to different material, we can make Silicon Carbide ceramic parts by Sintered Silicon Carbide (SSiC), Reaction bonded Silicon Carbide (SiSiC).
Features of Sintered silicon carbide seal faces.
1.High Temperature resistance, SiSiC can withstand 1380C, SSiC can withstand 1600C at most.
2.High strength and excellent hardness.
3.Good Corrosion and Oxidization resistance.
4.Tight tolerance and good surface roughness.
