Tungsten diboride
Azurfa farin farin octagonal crystal.
Yawan dangi 10.77, narkar da kusan 2900 ℃.
Rashin narkewa cikin ruwa, mai narkewa a cikin ruwa regia.
Boron da tungsten foda an haɗa su da zafi mai zafi.

Tungsten boride yana da mahimman narkewa, ƙarfin wuya, kwanciyar hankali na sinadarai da sauran kyawawan kaddarorin. Ba sabon sabon abu bane kawai, amma kuma yana da tsananin ƙarfi. Abu ne mai mahimmanci mara kariya ga kayan soja. Tungsten boride yana da zane-zane iri-iri masu yawa, kuma tsarin abubuwa daban-daban shima mai canzawa ne. Fiye da shekaru 50, mafi girman kyautar tungsten ana tsammanin WB4 ne, wanda ke da madaidaitan layin goro na atom guda uku. Anyi nazari akan daidaito na thermodynamic da kayan inji na tsarin tsarin tsarin tungsten carbide ta hanyar haɗa lissafin farko tare da kwanciyar hankali na thermodynamic:

Mafi girman kyauta don gano tungsten ya kamata ya zama WB3 wanda ya ƙunshi 2-d planar boron atoms, ba WB4 wanda ya kunshi 3-D grid atom masu girma uku.
An gano cewa yanayin gyaran fuska yana ƙaruwa tare da raguwar ƙarfinta a cikin tsarin tungsten, yana bayyana cewa kayan aikin inji suna da alaƙa da yanayin kwanciyar hankali na thermodynamic.
Saboda keɓaɓɓun kayan aikin injiniya, lantarki da magnetic, tungsten boride ya jawo hankali sosai a cikin bincike na asali da aikace-aikacen kimiyyar kayan abu.
Saboda ƙananan yaduwar kyauta na WB2, a halin yanzu, yawancin dungsten diboride ana samun su ta hanyar ɓoyewa a ƙarƙashin babban zafin jiki da matsin lamba. A gefe guda, saboda B yana bushewa a yanayin zafi mai zafi. Sabili da haka, shirya kai tsaye na kayan toshe WB2 tare da tungsten foda da boron foda yana da wahalar sarrafa abun cikin boron, kuma ana iya samar da ƙananan alfanu (kamar W2B) a cikin aikin ɓarna, don haka kayan toshi mai yawa tare da WB2 a matsayin babban lokaci ba za a iya samu gaba daya.
Filin Aikace-aikace:
Sanya - rufi mai tsayayya da fim din semiconductor don lalacewa - sassan juriya
