Tantalum carbide hardness, siab melting point, kub ua haujlwm siab, feem ntau yog siv ua cov khoom siv ntxiv rau cov hlau nplaum. Qhov thermal hardness, thermal shock resistance thiab thermal oxidation resistance ntawm cemented carbide tuaj yeem txhim kho tau zoo los ntawm kev nce qhov loj ntawm cov noob ntawm tantalum carbide. Tau ntev, ib qho tantalum carbide ntxiv rau tungsten carbide (lossis tungsten carbide thiab titanium carbide), thiab cov hlau cobalt uas ua rau cov hlau nplaum sib xyaw, tsim, thiab sintered los ua cov hlau nplaum tawv. Txhawm rau kom txo tus nqi ntawm cov hlau nplaum tawv, tantalum niobium compound carbide feem ntau siv. Tam sim no kev siv tseem ceeb ntawm tantalum niobium compound yog: TaC:NbC yog 80:20 thiab 60:40, thiab lub zog ntawm niobium carbide hauv cov khoom sib xyaw ncav cuag 40% (feem ntau tsis pub ntau tshaj 20% zoo dua).
