niobium oxide ufa
Mafotokozedwe Akatundu
Niobium pentoxide powder ndi chinthu chofunika kwambiri, mankhwala ake akuluakulu ndi niobium pentoxide (Nb2O5).Zinthu zakuthupi za niobium pentoxide ufa zimaphatikizapo mawonekedwe ake a kristalo, kachulukidwe, malo osungunuka ndi malo otentha.Niobium pentoxide powder imakhalanso ndi kukhazikika kwabwino kwa kutentha, zomwe zimathandiza kuti zikhale zokhazikika m'madera otentha kwambiri.Mankhwala a niobium pentoxide ufa amaphatikizapo asidi-base, kuchepetsa oxidation ndi zina zotero.Niobium pentoxide ufa ndi wosasungunuka m'madzi, koma umasungunuka mu asidi ndi maziko, kusonyeza asidi-alkali.Niobium pentoxide ilinso ndi oxidative reducibility ndipo imatha kukhala oxidized kapena kuchepetsedwa pa kutentha kosiyana ndi mlengalenga.Niobium pentoxide ufa uli ndi ntchito zambiri m'magawo ambiri.M'makampani amagetsi, ufa wa niobium pentoxide ukhoza kugwiritsidwa ntchito popanga zida zamagetsi, zida zowoneka bwino komanso kutentha kwambiri.M'munda wa zokutira, niobium pentoxide ufa angagwiritsidwe ntchito pokonzekera zokutira zapamwamba kalasi ndi inki.Komanso, niobium pentoxide ufa Angagwiritsidwenso ntchito popanga galasi kuwala, ziwiya zadothi ndi chothandizira.
