ʻO Kina ka mea kūʻai aku i ke kumu kūʻai nui CAS 12138-09-9 Tungsten Disulfide Price WS2 Powder High-Entropy Alloys

Ua hoʻohana ʻia ʻo Tungsten disulfide (WS2) i loko o ka nui no nā makahiki he nui ma ke ʻano he lubricant maloʻo ma muli o ke ʻano o ka hōʻike ʻana i nā waiwai o kahi coefficient haʻahaʻa o ka friction, ke kūpaʻa kemika kiʻekiʻe, a me ke kūpaʻa wela. I ka makahiki 1992, ua ʻike ʻia ua hiki i ke ʻano o WS2 ke hana i nā hale nanotube. ʻO kēia mau nanotubes nā hiʻohiʻona mua o WS2 i hoʻohana ʻia ma ke ʻano he haʻahaʻa haʻahaʻa. Ma hope o ka loaʻa ʻana o nā ʻenehana exfoliation mechanical maʻalahi e hoʻokaʻawale i nā papa hoʻokahi o nā mea 2-D, ua hiki ke aʻo i nā waiwai o WS2 flakes. Ua hōʻike ʻia, e like me MoS2, ke hoʻololi ʻia ka band-gap o WS2 mai kahi ʻāpana-kaulike ʻole o 1.4eV i kahi ʻāpana-waha pololei o 2eV ke hoʻololi ʻia mai kahi mea nui i kahi mea 2-D. Ma muli o kāna band-gap, ʻike ʻia ʻo WS2 he mea hoihoi loa no nā wahi o ka noi. Loaʻa iā WS2 ka ratio kiʻekiʻe ma / off i nā transistors hopena, controllable spin a me ke awāwa polarisation, ikaika geometrical confinement o excitons, a me ka photoluminescence tunable. Eia hou, hiki i ka WS2 ke alakaʻi i ka hoihoi nui i nā wahi e like me nā photodetectors a me nā photovoltaics multi-junction. Ma waho aʻe, hoʻohana ʻia ʻo WS2, i hui pū me nā mea ʻē aʻe, ma ke ʻano he catalyst no ka hydrotreating o ka aila ʻaila. Hoʻohana ʻia ʻo Lamellar tungsten disulfide ma ke ʻano he lubricant maloʻo no nā mea hoʻopaʻa, bearings, a me nā mold ma lalo o ka inoa inoa Dicronite. Hoʻohana ʻia ʻo Tungsten disulfide (WS2) ma ke ʻano he lubricant paʻa e hiki ke kū i nā wela kiʻekiʻe. Hoʻohana ʻia ʻo ia ma ke ʻano he lubricant spray. Hoʻohana ʻia ʻo Tungsten sulfide ma ke ʻano he ʻāpana o nā catalysts no ka hydrotreating o ka ʻaila crude, hydrodesulfurization a me nā hopena hydrodenitrification. Loaʻa iā ia ka noi ma ke ʻano he solid-state secondary lithium battery cathodes a me nā mea electrochemical ʻē aʻe. Ua ʻike ʻia ua hana ia i nā nanotubes inorganic, ʻoi aku ka maikaʻi o ka hoʻoikaika ʻana ma mua o nā nanotubes carbon. ʻO ka hoʻohui ʻana o Tungsten sulfide i ka epoxy resin e hoʻomaikaʻi i ka hoʻopili ʻana, ka paʻakikī o ka haki a me ka hoʻokuʻu ʻana i ka ikehu. Loaʻa iā Tungsten sulfide kahi pseudo 2 dimensional structure me nā noi i ka ʻoihana Petrochemical ma ke ʻano he catalyst desulfurization. Ua huki mai nā nanoparticles Tungsten Sulfide i ka hoihoi noiʻi ma muli o ko lākou hiki i nā lubricants solid-state; nā uhi a me nā photocatalysts.
