Niobium nitride, lub teeb grey yog daj me ntsis, tus txheeb ze ceev yog 8.47g / cm3, lub taw tes melting yog 2300 ° C; Lub mohs hardness yog 8, microhardness yog 14.3gpa; Nws qhov kev hloov pauv hloov kho qhov kub tseem ceeb yog 15.6k. Insoluble hauv hydrochloric acid, nitric acid, sulfuric acid; soluble hauv concentrated acid daws acid thiab sulfuric acid thiab sulfuric acid nws kuj yog soluble hauv kub alkali lossis siab-siab li cov lus hais ua ke thiab emits ammonia.
Siv los ua cov cemented carbide additive, nws kuj tseem tuaj yeem tsim cov kev ua kom siab-purity niobium.
