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