Niobium Carbide NbC |Tantalum Carbide TAC

Kev piav qhia

Niobium Carbide NbC,Lub teeb xim av hmoov, nrog sodium chloride hom cubic crystal system, melting point 3490 ° C, boiling point 4300 ° C, ceev 7.56g / cm³, yog insoluble hauv dej thiab inorganic acid, tab sis soluble nyob rau hauv cov kua qaub sib xyaw ntawm hydrofluoric acid thiab nitric acid thiab tuaj yeem decomposed.Niobium Carbide tsis tuaj yeem tsuas yog siv los ua cov tshuaj ntxiv los tiv thaiv kev loj hlob ntawm cov nplej nplej kom nplua cov cemented carbide crystalline nplej hauv kev tsim cov cemented carbide, tab sis kuj tsim rau theem thib peb dispersed nrog lwm cov carbides tshwj tsis yog WC thiab Co, uas tuaj yeem txhim kho tau zoo. Lub thermal hardness, thermal shock kuj, kub nias kuj thiab oxidation kuj ntawm cemented carbide.Nrog rau qhov zoo ntawm kev txhim kho hardness thiab tawg toughness ntawm cov hlau, nws tuaj yeem siv los npaj cov khoom siv cemented carbide nrog kev ua haujlwm zoo heev.Tsis tas li ntawd, ua cov ntsiab lus melting ntau dua, siab hardness thiab tshuaj ruaj khov, NbC kuj tseem siv los ua cov khoom siv kub kub thiab cov tshuaj tsuag txheej hauv kev lag luam aerospace.
