Waea Tungsten kua paea mo te whakarewa korehau

Whakaahuatanga Poto:

Ko nga poti tungsten, kete me nga kakawaea ka hangaia mai i te tungsten teitei.O nga konganuku katoa i roto i te ahua parakore, ko te tungsten te ira whakarewa teitei (3422°C / 6192°F), te iti rawa o te pehanga kohu i nga mahana i runga ake i te 1650°C (3000°F) me te kaha o te kaha.Ko te Tungsten te iti rawa o te whakarea o te roha wera o tetahi whakarewa parakore.Ko tenei huinga o nga taonga ka waiho te tungsten hei rauemi pai mo nga puna whakaetonga.I roto i te whakaetonga, ka taea te whakakotahi ki etahi taonga penei i te Al me te Au.I roto i tenei take, me whakamahi tetahi atu rauemi whakaetonga penei i nga poti kua whakakikoruatia ki te alumina, nga kete ranei.Ko etahi atu rauemi e whai hua ana mo nga puna whakaetonga ko te molybdenum me te tantalum.
