niobium pentoxide ufa wa galasi la kuwala
Mafotokozedwe Akatundu
Niobium pentoxide ufa ndi woyera kapena wachikasu wolimba, wopanda fungo.Niobium pentoxide ufa ndi wosasungunuka m'madzi, koma umasungunuka mu potassium hydroxide wosungunuka ndi potaziyamu sulfate, komanso alkali zitsulo carbonates ndi hydroxides.Kuphatikiza apo, imasungunukanso mu hydrofluoric acid ndi hot sulfuric acid.Pazifukwa zina, niobium pentoxide amatha kuchitapo kanthu ndi sodium carbonate, sodium hydroxide, sulfure, mpweya ndi zinthu zina.Ukatenthedwa, niobium pentoxide imaphwanyika kupanga niobium oxide.Niobium pentoxide powder ndi chinthu chofunika kwambiri chamagetsi, chomwe chingagwiritsidwe ntchito popanga makristasi apamwamba a lithiamu niobate, komanso kukonzekera ma oxides ena apamwamba.Kuphatikiza apo, itha kugwiritsidwa ntchito ngati kafukufuku wasayansi.
