ʻO ka Hafnium diboride kahi ʻano aniani hina a loaʻa iā ia ka luster metala, me ka conductivity uila kiʻekiʻe a me ka waiwai kemika paʻa. Ma waho aʻe o kēia, ʻaʻole hiki ke ʻae ʻia me nā mea hoʻokalakupua a pau (koe wale nō ka Hf) i ka mahana o loko. ʻO ia, kahi ʻano mea hana seramika hou me ka hana piha piha e like me ke kiʻekiʻe melting-point, kiʻekiʻe thermal conductivity, inoxidizability, etc., ua hoʻohana nui ʻia i nā kula e like me ka super kiʻekiʻe-mehana seramika, kiʻekiʻe-wikiwiki mokulele ihu. cone a me aerospace, etc.

ʻO ka Hafnium diboride kahi aniani ʻeleʻele hina-ʻeleʻele ʻeleʻele nona ka hale aniani i ka ʻōnaehana hexagonal. Ma ke ʻano he mea hoʻoheheʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe, hafnium diboride (HfB2) he wahi hoʻoheheʻe kiʻekiʻe (3380 ℃), hoʻohana pinepine ʻia i ka mea anti-ablation i ke kiʻekiʻe-mehana oxidation kaiapuni a loaʻa nā ʻano o ka paʻakikī kiʻekiʻe, kiʻekiʻe. modulus, kiʻekiʻe thermal conductivity a kiʻekiʻe conductivity. Hoʻohana nui ʻia ia i nā lole pale pale, nā mea refractory, nā mea hana ʻoki a me nā ʻōnaehana pale wela aerospace a me nā māla ʻē aʻe.
