Vanadium Powder, V

ʻO Vanadium kahi metala kālā-hina hina. ʻO ka helu hoʻoheheʻe ʻo 1890 + 10C ʻo ia kekahi o nā metala laha ʻole me ke kiko hoʻoheheʻe kiʻekiʻe. He wahi paila kona o 3380C, paʻakikī ka vanadium maʻemaʻe, non-magnet a malleable, akā ʻo kahi liʻiliʻi o nā impurities, ʻo ia hoʻi ʻo nitrogen, oxygen a me hydrogen, hiki ke hoʻoliʻiliʻi nui i kāna palakiko.

Vanadium: hōʻailona element V, kala hina hina hao, i ka papa manawa no VB pūʻulu, helu atomic 23, atomic weight 50.9414, aniani BCC, + 5, + 4, + 3, + 2. He kiʻekiʻe hoʻoheheʻe ko Vanadium kuhi a kāhea pinepine ʻia me nā metala refractory me ka niobium, tantalum, tungsten a me molybdenum. He malleable, paʻakikī a ʻaʻohe mākēneki.

Loaʻa iā ia ka hiki ke pale aku i ka waikawa hydrochloric a me ka waikawa sulfuric, a ʻoi aku ka maikaʻi ma mua o ka hapanui o nā kila kila i ke kinoea, paʻakai a me ka wai kūpaʻa kūpale. I ka mahana wela, kūpaʻa mau ka mokuʻāina paʻa o vanadium. ʻAʻole ia e pane me ka ea, ka wai a me ka alkali, a kūpaʻa i ka dilute acid. ʻO Vanadium kahi metala hina hina kālā. ʻO 1890 ± 10 ℃ ke kiko hoʻoheheʻe, ʻo ia kekahi o nā metala laha ʻole me ke kiko hoʻoheheʻe kiʻekiʻe. ʻO 3380 ℃ kona wahi e hoʻolapalapa ai, paʻakikī ka vanadium maʻemaʻe, non-magnet and ductile, akā inā loaʻa kahi liʻiliʻi o nā impurities, ʻoi aku hoʻi me ka nitrogen, oxygen, hydrogen, a pēlā aku.
