Tungsten carbide pob, nrog cov tshuaj muaj tshuaj WC (tag nrho lub npe Wolfram carbide), tshwm li dub hexagonal muaju nrog nws yog xim hlau luster. Lawv muaj lub hardness ze ntawm lub pob zeb diamond thiab yog cov neeg saib xyuas zoo ntawm hluav taws xob thiab cua sov. Lawv muaj lub ntsiab lus melting ntawm 2870℃thiab lub qhov cub npau npau ntawm 6000 degree, nrog lub ntom ntom ntawm 15.63 g / cm³ (ntawm 18 degree). Tungsten carbide yog insoluble hauv dej, hydrochloric acid, thiab sulfuric acid, tab sis yog soluble acid thiab hydrofluoric acid. Ntshiab tungsten carbide yog nkig, tab sis nws brittleness muaj peev xwm txo los ntawm kev ntxiv cov me me ntawm cov hlau xws li titanium lossis cobalt. Rau cov cuab yeej hlau txiav, tungsten carbide yog feem ntau nrog titanium carbide, lossis sib xyaw kom txhim kho nws cov anti - khob cov khoom. Tungsten carbide yog chemically ruaj khov. Nws cov kev npaj tau cuam tshuam cov tshuaj tiv thaiv ntawm tungsten thiab carbon thaum muaj kev sib ntxiv ntawm hydrogen lossis hydrocarbons kom nrawm dua cov tshuaj tiv thaiv. Yog tias oxygen -} muaj cov ntsiab lus sib txuas, nws yuav tsum tau kho hauv lub tshuab nqus tsev ntawm 1500℃kom tshem tawm impurities.
Ditungsten carbide (W2C) muaj cov khoom zoo sib xws rau tungsten carbide, nrog melting carbide, nrog melting thiab boiling cov ntsiab lus ntawm 2860 degree, feem, thiab ib qho ntom ntawm 17.15 g / cm3. Nws lub hardness yog ob tsuas yog rau ntawm pob zeb diamond, thiab nws ua pov thawj zoo heev rau cov tshuaj ruaj khov zoo nkauj heev nrog cov sulfroic acid thiab sulfuric acid thiab sulfuric acid txawm tias kub. Nws tseem yog qhov ruaj khov nyob rau hauv cov muaj zog acids xws li Aqua Regia. Vim nws qhov kev kub siab tiv thaiv thiab hardness, tungsten tau suav hais tias yog ib qho ntawm cov feem ntau insoluble hlau nyob rau hauv qhov, xav tau qhov kub heev rau kev ua siab.
Hauv kev siv cov kev siv, peb lub pob carbide carbide pob tau siv nyob rau hauv precision carras, ntws meters, thiab pen kev tsim khoom, uas lawv cov khoom siv zoo dua ua rau lawv muaj cov khoom siv tsis tau.
