Silicon Carbide: Nws yog cov khoom siv tsis zoo nrog cov tshuaj formula SiC, uas yog smelted nrog quartz xuab zeb, roj av coke (los yog coke coke), ntoo chips (tsim yog xav tau los tsim ntsuab silicon carbide) thiab lwm yam raw khoom los ntawm kub smelting hauv lub cub tawg kuj.
Silicon carbide vim nws cov khoom ruaj khov, thermal conductivity, me me coefficient ntawm thermal expansion, zoo hnav tsis kam, ntxiv rau abrasives, muaj ntau lwm yam kev siv, xws li: ib tug tshwj xeeb txheej txheem rau silicon carbide hmoov coated nyob rau hauv lub impeller ntawm hydraulic turbine los yog cov phab ntsa sab hauv ntawm lub tog raj kheej lub cev tuaj yeem txhim kho nws cov hnav tsis kam thiab txuas ntxiv lub neej kev pab cuam ntawm 1 mus rau 2 zaug; siv los ua cov refractories siab, kub poob siab, me me, lub teeb yuag thiab siab zog, lub zog txuag cov nyhuv yog qhov zoo.
(muaj SiC txog 85%) yog cov deoxidiser zoo heev, nws tuaj yeem siv los ua kom nrawm nrawm ntawm steelmaking, thiab pab tswj cov tshuaj muaj pes tsawg leeg, txhim kho cov hlau zoo. Tsis tas li ntawd, silicon carbide kuj tseem siv ntau hauv kev tsim hluav taws xob cua sov cov khoom silicon carbon rods. Silicon carbide hardness yog loj heev, Mohs hardness ntawm 9.5, thib ob tsuas yog lub ntiaj teb no hardest pob zeb diamond (10), muaj zoo thermal conductivity, yog ib tug semiconductor, kub oxidation kuj.
