.68克/厘米3，熔點(diǎn)1890℃，沸點(diǎn)3800℃。顯微硬度2200-2700kg/mm2，熱膨脹系數(shù)10.3×10-6/K。它是一種在高溫環(huán)境下（1000～1100℃）具有良好的耐磨、耐腐蝕、抗氧化的高熔點(diǎn)無(wú)機(jī)材料，被大量用作金屬表面保護(hù)的熱噴涂材料和耐磨焊條，也常用作硬質(zhì)合金的晶粒細(xì)化劑及其他耐磨、耐腐蝕元件。以Cr3C2為基的金屬陶瓷在高溫下有極優(yōu)異的抗氧化性能，在982℃熱暴露5小時(shí)之后，表面僅稍微變暗；而在相同條件下，18-8不銹鋼已顯著破壞，WC-6Co合金則完全氧化。<br><br><br>碳化鉻產(chǎn)品應(yīng)用、技術(shù)性能:<br>
