Niobium Nitride, lub teeb grey yog daj me ntsis, tus txheeb ze ntom yog 8.47g / cm3, lub melting point yog 2300 ° C; Mohs hardness yog 8, microhardness yog 14.3Gpa; nws cov kev hloov pauv hloov pauv tseem ceeb yog 15.6K. Insoluble hauv hydrochloric acid, nitric acid, sulfuric acid; Soluble nyob rau hauv concentrated acid tov ntawm hydrofluoric acid thiab sulfuric acid Nws kuj yog soluble nyob rau hauv kub alkali los yog high-concentration lye thiab emits ammonia.
Siv los ua cov cemented carbide additive, nws tuaj yeem tsim cov niobium siab.
