ʻO CAS 7440-62-2 V ke kumu kūʻai o ka pauka Vanadium Powder

ʻO Vanadium: ʻeleʻele hōʻailona V, metala hina hina, no ka hui VB i ka papaʻaina, helu ʻātoma 23, Ke kaumaha ʻĀtoma 50.9414, ke aniani cubic i waena o ke kino, ʻo ka valence maʻamau he +5, +4, +3, +2. He kiʻekiʻe loa ka helu heheʻe o Vanadium, a pinepine me ka niobium, tantalum, tungsten, molybdenum e like me ke metala refractory. Malleable, He paakiki a non-magnetic. He kūpaʻa ia i ka waika hydrochloric a me ka sulfuric, a ua kū i ke kinoea, paʻakai, ʻoi aku ka maikaʻi o ka pale wai ma mua o ka nui o nā mea kila. ʻOi aku ka paʻa o ka metala Vanadium ma ke ʻano paʻa i ka lumi wela. ʻAʻole ia e launa pū me ka ea, ka wai a i ʻole ka alkali a hiki ke pale aku i nā waikawa dilute ʻO Vanadium he metala hina hina. ʻO ka helu hoʻoheheʻe he 1890 ± 10 ℃, ʻo ia kekahi o nā metala liʻiliʻi me ka helu heheʻe kiʻekiʻe. He wahi paila ia o 3380 ° C, paʻakikī ka vanadium maʻemaʻe, non-magnetic, malleable, akā inā i loaʻa ʻO kahi liʻiliʻi o nā haumia, ʻoi aku ka nitrogen, oxygen, a me ka hydrogen, hiki ke hoʻemi nui i kā lākou plasticity.
