Some customer is not 100% clear the definite meaning by different SiC ceramics, so lead to wrong choices and make higher cost of production. Now Tangshan Hanwei help you clear this issue by simple words, hope helpful for your understanding: 

 RSiC = Recrystallized Silicon Carbide Max working temp is 1650℃, key feature is very high temperature! mainly used for ultra-high temperature fields, like: kiln furniture of technical ceramics (Alumina industrial ceramic, Zirconia fine ceramics).  

 NSiC = Nitride bonded Silicon Carbide Max working temp is 1450℃, key feature is high strength & excellent resistance of molten metal under high temp! Mainly used for porcelain kiln furniture, riser stalk tube & thermocouple sheath. 

 SiSiC = Sintered Silicon Carbide,also named RBSiC=Reaction Bonded SiC ceramicMax working temp is 1380℃, key feature is high strength & wear resistance under 1380℃. mainly used for dinner wares kiln furnitures, sanitary wares kiln parts, inner lining of engineering pipes.

 Above 3 kinds of SiC advanced ceramic also have common features, like high temperatue resistance, oxygen resistance, wear-resistance, high thermal conductivity,light weight etc, and they are getting more aplications nowadays, we can see different applications match specific material, only choose right material then achieved most cost-effective goods. We are good at gathering advantages so that help our customers get more value. Welcome to contact us by WhatsApp: 0086-159 3053 6865 (24 hours)..
