ʻO nā mea hoʻohui honua laha ʻole a me kā lākou hoʻohana ʻana

Koe wale no kekahinā mea ʻāina laha ʻolee hoohana pololei anametala lepo laha ole, ʻo ka hapa nui o lākou he pūhui e hoʻohananā mea ʻeleʻele rare. Me ka hoʻomohala wikiwiki ʻana o nā ʻenehana kiʻekiʻe e like me nā kamepiula, kamaʻilio fiber optic, superconductivity, aerospace, a me ka ikehu atomic, ʻo ke kuleana o nā mea ʻenekele honua a me kā lākou pūhui i kēia mau kahua e lilo i mea nui. Aia nā ʻano mea like ʻole o nā mea hoʻohui honua laha, a ke hoʻonui mau nei lākou. Ma waena o nā ʻano 26000 o nā pūhui honua laha ʻole, aia ma kahi o 4000 mau mea ʻano like ʻole o ka honua me nā hale i hoʻopaʻa ʻia.

ʻO ka synthesis a me ka hoʻohana ʻana i nā oxides a me nā oxides composite ka mea maʻamau i waenahonua lahapūhui, no ka mea, he pili ikaika ko lākou no ka oxygen a maʻalahi ke synthesize i ka lewa. Ma waena o nā pūhui honua laha ʻole me ka oxygen, ʻo nā halides a me nā halides composite ka mea maʻamau i hoʻopaʻa ʻia a aʻo ʻia, ʻoiai ʻo ia nā mea maka no ka hoʻomākaukau ʻana i nā mea hoʻohui honua laha ʻole a me nā metala honua laha. I nā makahiki i hala iho nei, ma muli o ka hoʻomohala ʻana i nā mea hou ʻenehana kiʻekiʻe, ua mālama ʻia ka noiʻi nui e pili ana i ka synthesis a me ka hoʻohana ʻana i ka oxygen free rare earth compounds e like me rare earth sulfides, nitride, borides, a me nā mea paʻakikī honua, me ka piʻi nui ʻana. .
