Silicon carbide ceramic is good at resistance to abrasion, corrosion and high temperatuer. Its anti-abrasion parameter is 5 times better than Cr26 steel.
The wear life can be 3-6 times of metal slurry pumps
The SiC is used as the meterial for making volute liner,impeller,front and rear protection,which are bonded with metal shell without seam.
Corrosion Resistance:
With stable chemical property, SiC can stand nearly all kinds of corrosion of mineral acid,organic acid,alkali,and it also has great antioxidant performance.
Wear Performance:
The silicon carbide crystal structure is similar to the diamond tetrahedron, and it is a compound composed of covalent bond, and the hardness of SiC is only next to diamond. Through the comparative test of Xi ' an Jiaotong university, its abrasion resistance is 3.51 times of Cr30 wear-resisting steel.
