Tungsten carbide hmoov (WC) yog cov khoom siv tseem ceeb rau kev tsim khoom ntawmtungsten carbide, chemical formula WC.tag nrho lub npe, tungsten carbide hmoov yog ib tug dub hexagonal siv lead ua, metallic luster, hardness thiab pob zeb diamond zoo ib yam li cov neeg xyuas pib zoo ntawm hluav taws xob thiab cua sov.Melting point 2870 ℃, boiling point 6000 ℃, txheeb ze ntom ntom 15.63 (18 ℃).Tungsten carbide yog insoluble nyob rau hauv dej, hydrochloric acid thiab sulfuric acid, soluble nyob rau hauv nitric acid - hydrofluoric acid tov.Ntshiab tungsten carbide yog qhov tsis yooj yim, yog tias sib xyaw nrog me me ntawm titanium, cobalt thiab lwm yam hlau, nws tuaj yeem txo qhov brittleness.Siv los ua cov cuab yeej steeltungsten carbide, feem ntau ntxiv titanium carbide, tantalum carbide los yog sib tov ntawm lawv los txhim kho lub peev xwm tiv thaiv tawg.
Cov yam ntxwv ntawm tungsten carbide yog ruaj khov.Tungsten carbide hmoov yog tsuas yog siv nyob rau hauv zus tau tej cov cemented carbide.Nyob rau hauv tungsten carbide hmoov, carbon atoms yog embedded nyob rau hauv lub interstices ntawm lub tungsten hlau lattice thiab tsis rhuav tshem cov thawj hlau lattice, tsim ib tug interstitial khoom tov, yog li nws tseem hu ua gap-filling (los yog insertion) compounds.
Cov tsos ntawm tungsten carbide hmoov yog grey, nrog rau qhov nce ntawm cov khoom particle loj, xim ntawm tsaus rau lub teeb.Cov xim yuav tsum sib npaug thiab zoo ib yam, tsis muaj qhov pom kev pom.
