nano-chromium carbide / nano CrC 80nm 99.9%
Cov yam ntxwv tseem ceeb ntawmnano-chromium carbide ultrafine chromium carbide hmoov npaj los ntawm ib txoj kev tshwj xeeb, cov hmoov yog orthorhombic, a = 2.821, b = 5.52, c = 11.46, qhov ceev ntawm qhov sib piv 6.68, qhov taw tes yaj 1890 ° C, qhov taw tes kub 3800 ° C, qhov coefficient ntawm thermal expansion ntawm 10.3 x 10-6 / K; chromium (chromium oxide) thiab cov pa roj carbon sib xyaw los ntawm qhov kub siab ntawm 1400-1600 ℃, chromium carbide lattice ntawm qhov zoo thiab qhov tsis zoo, qhov ceev yog 6.613 g / cm3, qhov taw tes yaj ntawm 1895 ℃. chromium carbide yog grey rau acid.
Cov yeeb yaj kiab tiv thaiv kev hnav, cov yeeb yaj kiab semiconductor; Carbide ntau lawm los ntxiv Cr3C2 tsis tsuas yog tuaj yeem txhim kho qhov loj ntawm WC thiab txhim kho lub zog tensile thiab hardness thiab tuaj yeem txhim kho qhov corrosion tsis kam ntawm alloy hauv kev lag luam ntau lawm yog dav siv ua cov khoom siv corrosion-resistant alloy (gauge valve, sealing rings, thiab lwm yam)
siv rau kev txau vuam thiab qhov yuav tsum tau ua ntawm ob qho tib si corrosion tsis kam thiab qhov nyuaj ntawm qhov siab tsis kam rau kev sib txhuam kev ua tau zoo solder; dav siv hauv stainless hlau, kub resistant hlau, corrosion-resistant hlau, alloy hlau thiab tshwj xeeb steel smelting ntau lawm
