He aha ka Rare Metal?
No nā makahiki i hala iho nei, lohe pinepine mākou i ka "pilikia metala laha ʻole" a i ʻole "ka pilikia metala paʻakikī". ʻO ka huaʻōlelo, "metala laha ʻole", ʻaʻole ia he mea i wehewehe ʻia ma ke kula, a ʻaʻohe manaʻo e pili ana i ka mea e pili ana. I kēia mau lā, hoʻohana pinepine ʻia ka huaʻōlelo e kuhikuhi i nā mea metala 47 i hōʻike ʻia ma ke Kiʻi 1, e like me ka wehewehe i hoʻonohonoho maʻamau. I kekahi manawa, helu ʻia nā ʻano ʻano ʻano like ʻole he 17, a ʻo ka huina he 31. Aia ka huina o 89 mau mea i loaʻa i ka honua kūlohelohe, a no laila, hiki ke ʻōlelo ʻia ʻoi aku ma mua o ka hapalua o nā mea he mau metala laha. .
ʻO nā mea e like me ka titanium, manganese, chromium, i loaʻa i ka nui i loko o ka ʻōpala o ka honua, ua manaʻo ʻia hoʻi he mau metala kakaʻikahi. ʻO kēia no ka mea he mau mea koʻikoʻi ka manganese a me ka chromium no ka honua ʻoihana mai kona mau lā mua, i hoʻohana ʻia i mea hoʻohui e hoʻomaikaʻi i nā waiwai o ka hao. Manaʻo ʻia ʻo Titanium he "ʻokoʻa" no ka mea he metala paʻakikī ia e hana ʻia no ka mea e koi ʻia ka ʻenehana kiʻekiʻe no ka hoʻomaʻemaʻe ʻana i ka ʻeleʻele nui ma ke ʻano o ka titanium oxide. Ma ka ʻaoʻao ʻē aʻe, mai nā kūlana mōʻaukala, ʻaʻole i kapa ʻia ke gula a me ke kālā, ka mea i ola mai ka wā kahiko, mai nā kūlana mōʻaukala, ke gula a me ke kālā, ka mea i ola mai ka wā kahiko, ʻaʻole i kapa ʻia nā metala laha. .
