1. Selelekela
Vanadium pentoxide ke oxide e tloaelehileng ka ho fetisisa ea vanadium, e hlahang e le phofo ea kristale e mosehla oa lamunu kapa solid e flaky. E bontša litšobotsi tsa amphoteric oxide, e qhibiliha hanyane ka metsing, 'me e qhibiliha habonolo ka har'a li-acid le alkali. Sebopeho sa eona sa kristale se nang le mekhahlelo le boemo ba valence bo feto-fetohang li etsa hore e se ke ea nkeloa sebaka ke catalysis, polokelo ea matla a electrochemical le lisebelisoa tsa optical. Ka nts'etsopele ea matla a macha a lefats'e, lik'hemik'hale tse ntle, le liindasteri tsa tlhahiso tse phahameng, tlhoko ea vanadium pentoxide e hloekileng haholo le e sa hloekang e ntse e tsoela pele ho hola. Jwalo ka mohlahisi e moholo ka ho fetisisa oa vanadium lefatšeng, Chaena, ka ho sebelisa melemo ea eona ea mehloli le tsoelo-pele ea theknoloji, e fetohile sehokelo sa mantlha ketane ea phepelo ea vanadium pentoxide lefatšeng ka bophara.
