Hafnium diboride hana:
Paʻa kemika ʻo Hafnium diboride. Aneane ʻaʻohe pane me nā kinikini a pau i ka wela lumi (koe wale nō ka HF).
ʻO ka Hafnium diboride me ka maʻemaʻe kiʻekiʻe, ka liʻiliʻi liʻiliʻi, ka hāʻawi like ʻana, ka ʻāpana kikoʻī nui, ka hana ʻili kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa i koho maikaʻi loa iā ʻoe e hoʻomohala a hana i nā huahana hou i hoʻohui ʻia.
Hafnium diboride noi:
ʻO ka Hafnium diboride kahi aniani ʻeleʻele hina-ʻeleʻele ʻeleʻele nona ka hale aniani i ka ʻōnaehana hexagonal. Ma ke ʻano he mea hana seramika ultra-kiʻekiʻe loa, hafnium diboride (HfB2) he wahi hoʻoheheʻe kiʻekiʻe (3380 ℃), hoʻohana pinepine ʻia i ka mea anti-ablation i loko o ke kaiapuni oxidation kiʻekiʻe a loaʻa nā ʻano o ka paʻakikī kiʻekiʻe, modulus kiʻekiʻe, kiʻekiʻe thermal conductivity a me ka conductivity kiʻekiʻe. 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.
ʻO ke kūlana mālama ʻo Hafnium diboride:
Pono e mālama ʻia ʻo Hafnium diboride i kahi maloʻo, ʻoluʻolu a hoʻopaʻa ʻia o ke kaiapuni, e ʻoluʻolu, mai hōʻike i ka ea, ʻoi aku ka pale ʻana i ke kaumaha kaumaha, e like me ka lawe ʻana i nā waiwai maʻamau.
