Niobium ntụ ntụ
Niobium Powder (CAS No. 7440-03-1) bụ isi awọ isi awọ nke nwere nnukwu agbaze na mgbochi corrosion. Ọ na-enwe tint na-acha anụnụ anụnụ mgbe ekpughere ya na ikuku n'ime ụlọ ruo ogologo oge. Niobium bụ ihe na-adịghị ahụkebe, dị nro, nke a na-adịghị ahụkebe, ductile, metal na-acha ntụ ntụ. O nwere ihe owuwu cubic crystalline nke gbadoro ụkwụ na ya na n'ime anụ ahụ na kemịkal ya, ọ dị ka tantalum. Ọksidation nke igwe na ikuku na-amalite na 200 Celsius. Niobium, mgbe ejiri ya na alloying, na-eme ka ike dịkwuo mma. A na-eme ka ihe ndị na-arụ ọrụ ya dịkwuo mma mgbe ejikọtara ya na zirconium. Niobium micron ntụ ntụ na-ahụ onwe ya na ngwa dị iche iche dị ka ngwá electronic, alloy-mere, na ahụike n'ihi kemịkalụ, ọkụ eletrik na ihe eji arụ ọrụ.
