ʻIridium

He keʻokeʻo keʻokeʻo keʻokeʻo ʻo Iridium a ʻo ia ka metala kūpaʻa ʻoi loa i ʻike ʻia. He helu atomika kona 77 a he 192.22 ke kaumaha atomika. ʻO kona helu heheʻe he 2450 ℃ a ʻo ka helu hoʻolapalapa he 4130 ℃. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a i ʻole ka wai.
Hiki i ka Iridium ke ana i ka wela a hiki i ka 2100 ℃ me ka pololei kiʻekiʻe loa a me ka hoʻihoʻi. ʻO nā kiʻiʻoniʻoni i waiho ʻia me ka hoʻohana ʻana i ka Iridium e hōʻike ana i ke ʻano kūʻē o ka oxidation.
ʻO Rich Special Materials kahi mea hana o ka Sputtering Target a hiki ke hana i nā lako Iridium Sputtering maʻemaʻe kiʻekiʻe e like me nā kikoʻī o nā mea kūʻai aku. No ka 'ike hou aku, e 'olu'olu e leka uila mai.
