niobium pentoxide ufa wa galasi la kuwala
Mafotokozedwe Akatundu
Niobium pentoxide ufandi zofunika mankhwala zopangira.Ndiwonso ufa wakuda wokhala ndi malo osungunuka kwambiri komanso mankhwala okhazikika, omwe amapangidwa ndi zomwe zitsulo za niobium zimachita ndi mpweya pa kutentha kwakukulu.Niobium pentoxide powder imakhala ndi mankhwala okhazikika, osasungunuka m'madzi, ma acid ndi maziko, ndipo amangokhalira ndi hydrogen ndi carbon pa kutentha kwakukulu.Niobium pentoxide ufa amagwiritsidwa ntchito kwambiri mu zamagetsi, ziwiya zadothi, optics, chemistry ndi zina.M'munda wamagetsi, amagwiritsidwa ntchito ngati zida za cathode zamfuti za ma elekitironi, ndipo m'munda wa ceramics amagwiritsidwa ntchito ngati chowonjezera cha zida za ceramic kuti apititse patsogolo kuuma ndi kukana kutentha kwa ceramics.Komanso, niobium pentoxide ufa angagwiritsidwenso ntchito popanga zipangizo kuwala ndi zopangira mankhwala.
