ʻO ka pauka Niobium
ʻO ka Niobium Powder (CAS No. 7440-03-1) he hina hina me kahi kiʻekiʻe hoʻoheheʻe a me ka anti-corrosion. Lawe ia i kahi ʻulaʻula i ka wā e ʻike ʻia ai i ka ea ma nā wela lumi no nā manawa lōʻihi. ʻO ka Niobium he mea laʻa, palupalu, malleable, ductile, hina-keʻokeʻo metala. Loaʻa iā ia kahi hoʻolālā cubic crystalline e pili ana i ke kino a ma kona ʻano kino a me ke kino e like me ka tantalum. Hoʻomaka ka oxidation o ka metala ma ka ea ma 200°C. ʻO Niobium, ke hoʻohana ʻia i ka alloying, hoʻomaikaʻi i ka ikaika. Hoʻonuiʻia kona mau waiwai superconductive i ka huiʻana me ka zirconium. Loaʻa ka pauka Niobium micron iā ia iho i nā noi like ʻole e like me ka uila, ka hana alloy, a me ka lāʻau lapaʻau ma muli o kāna mau mea kemika, uila, a me nā mea hana.
