Cov yam ntxwv tseem ceeb ntawmnano-chromium carbide ultrafine chromium carbide hmoov npaj los ntawm cov txheej txheem tshwj xeeb, cov hmoov yog orthorhombic, a = 2.821, b = 5.52, c = 11.46, txheeb ze ntom ntom 6.68, melting point 1890 ° C, boiling point 3800 ° C, thermal expansion coefficient ntawm 10.3 x 10-6 / K;chromium (chromium oxide) thiab carbon compounds los ntawm qhov kub thiab txias ntawm 1400-1600 ℃, chromium carbide lattice ntawm zoo thiab tsis zoo, ceev yog 6.613 g / cm3, ib tug melting point ntawm 1895 ℃.chromium carbide yog grey rau acid.
Daim ntawv thov
Ib qho yeeb yaj kiab tiv thaiv, cov yeeb yaj kiab semiconductor;
Carbide ntau lawm ntxiv rau Cr3C2 tsis tsuas yog tuaj yeem kho cov WC lis loj thiab txhim kho lub zog tensile thiab hardness thiab tuaj yeem txhim kho cov hlau tsis muaj zog hauv kev tsim khoom yog dav siv los ua cov khoom siv corrosion-resistant alloy (gauge valve, sealing rings, etc.) ).dav siv nyob rau hauv stainless hlau, kub resistant steel, corrosion-resistant steel, alloy steel thiab tshwj xeeb steel smelting ntau lawm
