ʻO ke kaumaha o ka mole mole 200.112

Nā hiʻohiʻona nui:

Hafnium diboride (HfB2) kahi aniani ʻeleʻele hina me ka hinuhinu metallic. ʻO kāna ʻōnaehana aniani no ka ʻōnaehana hexagonal. Ma ke ʻano he pālolo pālua pāmahana maikaʻi loa,

He wahi hoʻoheʻe kiʻekiʻe ko HfB2 (3380 ℃), kiʻekiʻe kiʻekiʻe, ka liʻiliʻi o ka liʻiliʻi, ka hāʻawi like ʻana, kahi ʻāpana kikoʻī nui, kahi papa kiʻekiʻe, ka nui o ka nui o ka uila, conductivity uila kiʻekiʻe a me nā waiwai kemika paʻa. ʻAʻole paʻakikī ia me nā mea hana kime āpau koe ʻo HF ma ke ana wela o ka lumi. ʻO nā mea pālolo hou me kahi pae hoʻoheheʻe kiʻekiʻe, conductivity wela kiʻekiʻe a me ke kūpale ʻana i ka oxyidation

Hoʻohana nui:

Hoʻohana nui ʻia ia i nā keramika wela kiʻekiʻe, ka ihu ihu o nā mokulele holo wikiwiki, mokulele, mokulele a me nā māla ʻē aʻe. ʻO ia ka mea moho moho o nā keramika wela kiʻekiʻe. Hoʻohana pinepine ʻia ia ma ke ʻano he anti anti ablation material i kahi kiʻekiʻe o ka wela o ka wela o ka wela, a he mau ʻano ko ka paʻakikī kiʻekiʻe, he modulus kiʻekiʻe, he nui a me kahi conductivity kiʻekiʻe.
