- wear resistant ceramic rings for pumps
Silicon carbide ceramic / SiC ceramic is an ideal material for mechanical seal rings because it is a lightweight ceramic material with high strength properties comparable to diamond. The superior abrasion and corrosion resistance are also important reasons that people choose silicon carbide seal rings. Silicon carbide seal rings will have good sealing performance even under acid or alkali environment. Silicon carbide seal rings also have high heat resistance and good thermal shock resistance, the performance of wear resistance and strength are still excellent in high temperature.

Silicon carbide ceramic / SiC ceramic is an ideal material for mechanical seal rings because it is a lightweight ceramic material with high strength properties comparable to diamond. The superior abrasion and corrosion resistance are also important reasons that people choose silicon carbide seal rings. Silicon carbide seal rings will have good sealing performance even under acid or alkali environment. Silicon carbide seal rings also have high heat resistance and good thermal shock resistance, the performance of wear resistance and strength are still excellent in high temperature.
Mascera is a specialist for tailor-made silicon carbide seal rings, the material could be Reaction Bonded Silicon Carbide (RBSiC) or Sintered Silicon Carbide (SSiC), SSiC ceramic can work up to 1600℃ while SiSiC ceramic can only work less than 1300℃. The sealing surfaces of silicon carbide seal rings are ground and lapped to a mirror surface to provide satisfactory sealing performance. We provide silicon carbide seal rings for static ring, moving ring, flat ring, etc. Please let us know your specific need, we will provide exact product for you.
Mascera produced silicon carbide ceramics in two forms, sintered silicon carbide (SSiC) and reaction bonded silicon carbide (SiSiC).
Sintered silicon carbide ceramic is made of high-purity and nano-grade raw powders and sintered at a high temperature of 2100℃-2200℃, the sintering process will densify the green body and cause shrinkage approximately 20%; reaction boned silicon carbide uses micron-sized silicon carbide powder, the sintering temperature is 1450℃-1700℃, there is no shape shrinkage during sintering. The higher sintering temperature makes sintered silicon carbide having better performance, such as higher density, higher strength, better resistance to oxidation and corrosion; for applicatons which don't have so high properties requirement, reaction bonded silicon carbide is more cost effective.
