Nā ʻāpana Molybdenum Disilicide

ʻO Molybdenum Disilicide (MoSi2) kahi mea moho hoʻohiki no nā noi hoʻolālā kiʻekiʻe. He mea hoʻoheheʻe kiʻekiʻe (2030 °C) me ka maikaʻi o ka pale ʻana i ka oxidation a me ka haʻahaʻa haʻahaʻa (6.24 g/cm3). ʻAʻole hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā waikawa, akā hiki ke hoʻoheheʻe ʻia i loko o ka waikawa nitric a me ka waika hydrofluoric. ʻAʻole ʻokoʻa loa ka radii o nā ʻano ʻelua ʻelua, kokoke loa ka electronegativity, a he mau waiwai like ko lākou me nā metala a me nā seramika. He conductive ʻo Molybdenum Disilicide a hiki ke hana i kahi papa passivation o ka silicon dioxide ma luna o ka ʻili i nā wela kiʻekiʻe e pale ai i ka oxidation hou. Hoʻohana ʻia ia ma nā kahua o nā mea hoʻonaninani anti-oxidation kiʻekiʻe, nā mea hoʻomehana uila, nā kiʻi ʻoniʻoni electrode i hoʻohui ʻia, nā mea hoʻolālā, nā mea i hoʻohui ʻia, nā mea pale lole, nā mea hoʻohui ceramic structural a me nā māla ʻē aʻe.

Hiki ke hoʻohana ʻia ka Molybdenum Disilicide i nā ʻoihana like ʻole: 1) ʻOihana a me ka ʻoihana kemika: Hoʻohana ʻia ʻo MoSi2 ma ke ʻano he mea hoʻomehana uila, ka mea hoʻololi wela wela o ka mea hoʻoheheʻe atomika, mea puhi kinoea, thermocouple wela kiʻekiʻe a me kāna paipu pale, hoʻoheheʻe moku crucible. (hoʻohana ʻia no ka hoʻoheheʻe ʻana i ka sodium, lithium, lead, bismuth, tin a me nā metala ʻē aʻe) . 2) ʻOihana Microelectronics: ʻO MoSi2 a me nā Silicides refractory ʻē aʻe ʻo Ti5Si3, WSi2, TaSi2, a me nā mea ʻē aʻe he mau moho koʻikoʻi no nā puka kaapuni hoʻohui nui a me nā pilina. 3) ʻOihana Aerospace: ʻO MoSi2 ma ke ʻano he kiʻekiʻe ka wela anti-oxidation coating material, ʻoi aku ka nui o nā mea no nā ʻāpana ʻenekini turbine, e like me nā blades, impellers, nā keʻena puhi ahi, nā nozzles a me nā mea hoʻopaʻa inoa, ua ākea a hohonu ka noiʻi a me ka noi. . 4) ʻOihana kaʻa: Hoʻohana ʻia ʻo Molybdenum Disilicide MoSi2 i nā rotors turbocharger kaʻa, nā kino valve, nā pahu kukui a me nā ʻāpana mīkini.

Loaʻa nā waiwai kūikawā i ka hana ʻana i ka Sputtering Target a hiki ke hana i nā ʻāpana Molybdenum Disilicide e like me nā kikoʻī o nā mea kūʻai aku. No ka 'ike hou aku, e 'olu'olu e leka uila mai.
