Manganese Boride Powder, MnB2

Hiki ke hoʻohana ʻia e like me ke ʻano anti-oxidation, anti-erosion a hoʻomaikaʻi i ka ikaika wela o nā mea hoʻohui boron, hoʻohana ʻia me he ʻoihana nukelea, nā lako koa superconducting ʻoihana a me nā mea hou aʻe.

Ua loaʻa kēia ʻike ʻia e kahi kime i alakaʻi ʻia e Qiu Guangchun, he polofesa ma ke Keʻena ʻEpekema a me ʻEpekema ʻo Aoyama Gakuin. Loaʻa i kahi mea superconducting kahi pāhana hoʻoili superconducting e like me ke kiʻekiʻe o Tc = 39K (-234 drops) ke hāʻule ke kūʻē i ka ʻole. Kākau hou ka ʻike i ka moʻolelo no nā mea keleawe non-copper oxide superconducting material Tc. Ua mālama ʻo Mr. Akiko i kahi ʻaha kūkā nūhou ma ka lā 26 Pepeluali 2001 e hoʻolaha i nā hopena o ke aʻo ʻana. Ua hoʻokūpaʻa ʻia kekahi mau keʻena noiʻi ma Iapana a me nā ʻāina ʻē "i kēia ʻoiaʻiʻo ma o nā hoʻokolohua hou aʻe (International Center for Superconducting Industrial Technology Institute of Superconductivity second Research Director, Suko Tajima et al.). ʻO ke kiʻekiʻe o ka mahana hoʻololi o ka superconducting, ʻoi aku ka maʻalahi o ka hoʻohana. ʻAʻole kiʻekiʻe ka Tc o 39K.

I kēia manawa, ua loaʻa i nā kānaka kahi superconductor wela kiʻekiʻe (HgBa2Ca2Cu3O8) me Tc o 134K (-139 ℃). ʻO ka loaʻa ʻana o kahi superconductor hou i ʻumeʻume i ka nānā ma muli o kāna ʻano. I ka wā i hala, ua loaʻa ka nui o nā mahana superconducting e nā keleawe keleawe. No ka mea no ka papa keramika ke keleawe keleawe, he "paʻakikī e hana ʻia i ʻano linear, no laila ʻaʻole ia i hoʻohana ʻia a hiki i kēia manawa" (Qiu Guang). Ke hoʻohālikelike ʻia me kēia, ʻo ka mea hoʻohui metala manganese diboride i kēia mau maikaʻi aʻe.

(1) Manganese (Mg) a me boron (B) mea liʻiliʻi a maʻalahi hoʻi. "ʻO kēia ka hoʻohui maikaʻi loa no ka ʻoihana hana" (Autumn).
(2) ʻOiai he 700 ℃ wale nō ka mahana o ka synthes, no laila haʻahaʻa ka hana a me ka uku hana.
(3) ʻAʻole e hoʻopōʻino ʻia nā waiwai superconducting o ke kinikini i loaʻa i nā mea metala Mg a me ka manganese diboride inā hana ʻia ia i ke ʻano oka.
(4) Ma muli o ka haku ʻia ʻana o nā mea ʻelua, maʻalahi e synthesize i nā kiʻi ʻoniʻoni lahilahi.

ʻO nā mea kokoke loa i ka mea koi SQUID (superconducting quantum interferensi).
