ʻEleʻele honua laha ʻole | Terbium (Tb)

I ka makahiki 1843, ua ʻike ʻo Karl G. Mosander o Suedena i ka meahoʻopaʻapaʻa ma o kāna noiʻi ʻana ma ka honua yttrium. ʻO ka hoʻohana ʻana i ka terbium ka hapa nui o nā ʻenehana kiʻekiʻe, ʻo ia ka ʻenehana koʻikoʻi a me ka ʻike ikaika o nā papahana ʻokiʻoki, a me nā papahana me nā pōmaikaʻi waiwai nui, me nā manaʻo hoʻomohala hoihoi. ʻO nā wahi noi nui e pili ana i kēia.

(1) Hoʻohana ʻia nā Phosphors e like me nā mea hoʻouluulu ʻōmaʻomaʻo i loko o ʻekolu phosphors mua, e like me ka terbium activated phosphate matrix, terbium activated silicate matrix, a me ka terbium activated cerium magnesium aluminate matrix, e hoʻopuka ana i ke kukui ʻōmaʻomaʻo ma lalo o ka hauʻoli.

(2) ʻO nā mea hoʻopaʻa manaʻo magnetic, i nā makahiki i hala iho nei, ua hiki i ka terbium based magnetic optical material i kahi ʻano hana nui. Hoʻokumu ʻia nā disc optical magnetic me ka hoʻohana ʻana i nā kiʻi ʻoniʻoni ʻoniʻoni amorphous Tb-Fe no ka mea ua hoʻonui ʻia nā mea mālama kamepiula i ka hiki ke mālama ʻia e 10-15 mau manawa.

(3) Magneto aniani aniani, Faraday rotatory aniani i loaʻa ka terbium, he mea nui no ka hana ʻana i nā rotators, isolator, a me nā circulators i hoʻohana nui ʻia i ka ʻenehana laser. ʻO ka mea kūikawā, ua wehe ka hoʻomohala ʻana a me ka hoʻomohala ʻana o ka terbium dysprosium ferromagnetostrictive alloy (TerFenol) i nā hoʻohana hou no ka terbium. ʻO Terfenol kahi mea hou i ʻike ʻia i ka makahiki 1970, me ka hapalua o ka alloy i haku ʻia me ka terbium a me ka dysprosium, i kekahi manawa me ka holmium, a ʻo ke koena he hao. Ua hoʻokumu mua ʻia kēia alloy e ka Ames Laboratory ma Iowa, United States. Ke hoʻokomo ʻia ʻo Terfenol i loko o kahi māla magnetic, hoʻololi kona nui ma mua o nā mea magnetic maʻamau, Hiki i kēia hoʻololi ke hiki ke hoʻokō i kekahi mau neʻe mechanical pololei. Ua hoʻohana mua ʻia ʻo Terbium dysprosium iron i ka sonar a ua hoʻohana nui ʻia i nā ʻano ʻano like ʻole, me nā ʻōnaehana hoʻoheheʻe wahie, ka mana valve wai, ka micro positioning, nā mea hana mechanical, nā mīkini, a me nā mea hoʻoponopono ʻēheu no nā mokulele a me nā telescopes.
