Tungsten Boride, WB

Tungsten boride ili ndi malo osungunuka kwambiri, kuuma kwakukulu, kukhazikika kwamankhwala ndi zina

katundu wathunthu. Sizinthu zatsopano zokha zokha, komanso zili ndi mkulu

kulimba. Ndi chinthu chofunikira kwambiri chopewera zipolopolo kunkhondo. Tungsten boride ali nayo

zithunzi zambiri za gawo, ndi zomanga

Njira yamagulu  BW
Nambala ya CAS  12007-09
Makhalidwe  wakuda ndi imvi ufa
Kuchulukitsitsa  10,77 g / cm3
Kusungunuka 2900
Ntchito BW ili ndi malo osungunuka kwambiri, kuuma kwambiri, magwiridwe okwezeka komanso mawonekedwe apamwamba komanso kukana makutidwe ndi okosijeni kuzinthu zosiyanasiyana. Zinthu zabwinozikuluzi zimapangitsa kuti mankhwala a WB azigwiritsidwa ntchito m'malo ovutaKukuta zokutira komanso kutentha kwamagetsi pamagetsi, kuponyera nkhungu, mbiya ndi zina zotero.

Tungsten amatsogolera
Siliva yoyera octagonal crystal.
Kuchuluka kwa ubale 10.77, malo osungunuka pafupifupi 2900 ℃.
Zosasungunuka m'madzi, zosungunuka mu aqua regia.
Boron ndi ufa wa tungsten anali otenthetsera kutentha kwambiri.

Tungsten boride ili ndi malo osungunuka kwambiri, kuuma kwakukulu, kukhazikika kwamankhwala ndi zina zambiri. Sizinthu zatsopano zokha, komanso zimakhala zolimba kwambiri. Ndi chinthu chofunikira kwambiri chopewera zipolopolo kunkhondo. Tungsten boride ili ndi zithunzi zambiri, ndipo kapangidwe kazigawo zosiyanasiyana zimasinthanso. Kwa zaka zopitilira 50, boride wapamwamba kwambiri wa tungsten wakhala akuganiza kuti ndi WB4, yomwe ili ndi gridi yazithunzi zitatu yama boroni. Kukhazikika kwa thermodynamic komanso mawonekedwe amachitidwe a tungsten carbidesystem adaphunziridwa mwadongosolo pophatikiza kuwerengera koyambirira kokhazikika ndi kukhazikika kwa thermodynamic:
Okhazikika kwambiri pa chizindikiritso cha tungsten ayenera kukhala WB3 wopangidwa ndi ma atomu a 2-d a planar boron, osati WB4 opangidwa ndi ma gridi atatu a atatu-dimensional boron atom.
Zimapezeka kuti shear modulus imakula ndikuchepa kwa mphamvu yake yopanga mu boride system ya tungsten, kuwulula kuti makinawo ndi ofanana kwambiri ndi kukhazikika kwawo kwa thermodynamic.
Chifukwa cha makina ake, magetsi ndi maginito, tungsten boride yakopa chidwi chachikulu pakufufuza ndi kugwiritsa ntchito sayansi yakuthupi.
Chifukwa cha kuchepa kwa kuchepa kwaulere kwa WB, pakadali pano, kaphatikizidwe ka dung tenesten diboride imakwaniritsidwa makamaka chifukwa chokhala pansi ndi kutentha kwambiri. Kumbali inayi, chifukwa B imasanduka kotentha kwambiri. Chifukwa chake, amatsogolera kukonzekera kwa WB block block ndi tungsten ufa ndi boron ufa ndizovuta kuwongolera zomwe zili ndi boron, ndipo ma borides otsika (monga W2B) atha kupangika panthawi yopanga sintering, kuti zinthu zolimba zomwe zili ndi WB ndiye gawo lalikulu sangapezeke kwathunthu.
Gawo Loyeserera: Valani -movala zosagwira komanso filimu yama semiconductor yamagawo osagwirizana.
