Tungsten carbidehmoov (WC) yog cov khoom siv tseem ceeb rau kev tsim cov cemented carbide, nrog rau cov tshuaj formula WC.Lub npe tag nrho yog tungsten carbide hmoov.Nws yog ib tug dub hexagonal siv lead ua nrog ib tug metallic luster thiab ib tug hardness zoo ib yam li pob zeb diamond.Nws yog ib tug zoo conductor ntawm hluav taws xob thiab cua sov.Lub melting point yog 2870 ℃, lub boiling point yog 6000 ℃, thiab tus txheeb ze ceev yog 15.63 (18 ℃).TungstencarbideNws yog insoluble nyob rau hauv dej, hydrochloric acid thiab sulfuric acid, tab sis yooj yim soluble nyob rau hauv nitric acid-hydrofluoric acid tov.
Tungsten carbidehmoov yog cov hmoov grey tsaus thiab tuaj yeem yaj hauv ntau yam carbide, tshwj xeeb tshaj yog titanium carbide, uas muaj cov solubility siab los tsim cov tshuaj TiC-WC.Lwm qhov sib xyaw ntawm tungsten thiab carbon yog tungsten carbide, nrog rau cov tshuaj formula ntawm W2C, melting point ntawm 2860 ° C, boiling point ntawm 6000 ° C, thiab ib tug txheeb ze ntom ntawm 17.15.Nws cov khoom, kev npaj thiab kev siv yog tib yam li tungsten carbide hmoov.
Tungsten carbide hmoov yog tsuas yog siv nyob rau hauv zus tau tej cov cemented carbide.Hauvtungsten carbide hmoov, carbon atoms yog embedded nyob rau hauv qhov khoob ntawm lubtungsten hlaulattice yam tsis tau rhuav tshem cov thawj hlau lattice, tsim ib qho kev sib xyaw ua ke, yog li nws tseem hu ua interstitial (los yog insertion) compound.
