Kumukuai Hale Hana HfB2 Hafnium Diboride Pauda

ʻO ka Hafnium diboride (HfB2) he aniani hina-ʻeleʻele me ka luster metala, a ʻo kona ʻano aniani no ka ʻōnaehana hexagonal.Paʻa kona mau waiwai kemika, a ʻaʻole hiki ke hoʻokō me nā mea hoʻokalakupua a pau (koe wale nō ka HF) i ka mahana wela.Ma ke ʻano he mea hoʻoheheʻe kiʻekiʻe kiʻekiʻe loa, ʻo ka hafnium diboride he wahi hoʻoheheʻe kiʻekiʻe loa (3380 ° C), a hoʻohana pinepine ʻia ma ke ʻano he mea anti-ablation i nā kaiapuni oxidizing kiʻekiʻe.Loaʻa iā ia nā hiʻohiʻona o ka paʻakikī kiʻekiʻe, ka modulus kiʻekiʻe, ka conductivity thermal kiʻekiʻe a me ka conductivity uila kiʻekiʻe, no laila ua hoʻohana nui ʻia ia i nā lole pale pale, nā mea refractory, nā mea ʻoki a me nā ʻōnaehana pale wela aerospace a me nā māla ʻē aʻe.
