NINAU

ʻO Lanthanum Hexaboride (Lanthanum Boride, LaB6) ceramic kahi mea hana kiʻekiʻe me nā waiwai hoʻokuʻu electron maikaʻi loa i nā haʻahaʻa haʻahaʻa, e hoʻohana nui ʻia i nā ʻano ʻoihana kiʻekiʻe. ʻO kona mau hiʻohiʻona kūikawā e lilo ia i mea waiwai no ka wela kiʻekiʻe a me nā noi uila. Paʻa kemika ʻo LaB6 i loko o ka vacuum a ʻaʻole pili i ka makū. ʻO ka helu heheʻe kiʻekiʻe o Lanthanum Hexaboride, ʻoi aku ka maikaʻi o ka thermal conductivity, a me kekahi mau waiwai magnetic e kūpono ia no ka hoʻokuʻu ʻana i nā electron i nā pū electron, electron microscopes, a me nā kūlana kiʻekiʻe-mehana a me ka ʻūhā.
