Farashin Dillali na China CAS 12138-09-9 Tungsten Disulfide Farashin WS2 Foda High-Entropy Alloys

Tungsten disulfide (WS2) a cikin girma an yi amfani dashi tsawon shekaru da yawa azaman mai busasshen mai saboda yadda yake nuna kaddarorin ƙarancin juzu'i, babban kwanciyar hankali na sinadarai, da kwanciyar hankali na thermal. A cikin 1992, an gano cewa tsarin WS2 ya sanya shi iya samar da tsarin nanotube. Waɗannan nanotubes su ne misalan farko na WS2 da ake amfani da su azaman ƙaramin girman abu. Bayan gano hanyoyin daɗaɗɗen injiniyoyi masu sauƙi don keɓance yadudduka ɗaya na kayan 2-D, yana yiwuwa a yi nazarin kaddarorin flakes na WS2. An nuna cewa, kamar MoS2, ratar band na WS2 yana canzawa daga rata-band- kai tsaye na 1.4eV zuwa tazarar band-girgizar kai tsaye na 2eV lokacin canzawa daga babban abu zuwa kayan 2-D. Saboda ratar band ɗin sa, ana ganin WS2 a matsayin abu mai ban sha'awa mai mahimmanci ga yankuna da yawa na aikace-aikacen. WS2 yana da babban abin kunnawa/kashewa a cikin tasirin tasirin filin, mai iya sarrafa juzu'i da polarisation na kwari, ƙaƙƙarfan ƙaƙƙarfan ƙayyadaddun yanayin juzu'i na excitons, da ingantaccen hoto. Bugu da ƙari, WS2 na iya haifar da ƙarin sha'awa a cikin yankuna kamar masu gano hoto da hotuna masu haɗawa da yawa. Bayan haka, ana amfani da WS2, tare da wasu kayan, a matsayin mai kara kuzari don sarrafa danyen mai. Lamellar tungsten disulfide ana amfani dashi azaman mai busasshen mai don masu ɗaure, bearings, da gyare-gyare a ƙarƙashin sunan alamar Dicronite. Tungsten disulfide (WS2) ana amfani dashi azaman mai mai ƙarfi mai ƙarfi wanda zai iya jure yanayin zafi. Hakanan ana amfani dashi azaman mai mai feshi. Tungsten sulfide ana amfani dashi azaman ɓangaren abubuwan haɓakawa don hydrotreating na ɗanyen mai, hydrodesulfurization da halayen hydrodenitrification. Yana samun aikace-aikace azaman ƙaƙƙarfan jaha na biyu na batirin lithium cathodes da sauran na'urorin lantarki. An gano cewa yana samar da nanotubes na inorganic, wanda shine mafi kyawun ƙarfafawa fiye da carbon nanotubes. Tungsten sulfide ƙari ga resin epoxy yana inganta mannewa, taurin karaya da ƙarancin sakin kuzari. Tungsten sulfide yana da tsari mai ƙima mai ƙima 2 tare da aikace-aikace a cikin masana'antar Petrochemical azaman mai haɓakawa. Tungsten Sulfide nanoparticles sun jawo sha'awar bincike saboda yuwuwar su a cikin ma'auni mai ƙarfi; kayan shafawa da kuma photocatalysts.
