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 ka 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 hoʻomake hou ʻana.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 loko o nā ʻoihana he nui: 1) Energy a me ka ʻoihana kemika: Hoʻohana ʻia ʻo MoSi2 e like me ka mea hoʻomehana uila, ka mea hoʻololi wela wela o ka mea hoʻoheheʻe atomika, ka mea puhi kinoea, ka thermocouple wela kiʻekiʻe a me kāna paipu pale, ka ipu hoʻoheheʻe. (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 kiʻekiʻe anti-oxidation coating mea, ʻoi aku ka nui o nā mea no nā ʻāpana ʻenekini turbine, e like me nā lau, nā impellers, nā keʻena puhi ahi, nā nozzles a me nā mea hoʻopaʻa paʻa, 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.
