Sintered Tungsten (W) Crucible

Malo osungunuka a tungsten ndi okwera kufika pa 3410 ° C. Chifukwa chake, ma tungsten crucibles amagwiritsidwa ntchito kwambiri ngati zotengera zoyambira m'ng'anjo zamafakitale monga ng'anjo za safiro single crystal kukula, ng'anjo zosungunula magalasi a quartz, ndi ng'anjo zosungunula zapadziko lapansi. Kutentha kwa ntchito nthawi zambiri kumakhala pamwamba pa 2000 ° C.

Kwa ng'anjo zokulirapo za safiro, ma tungsten crucibles okhala ndi chiyero chambiri, kachulukidwe kakang'ono, osang'ambika mkati, miyeso yolondola, komanso makoma osalala amkati ndi akunja atha kupititsa patsogolo kwambiri kupambana kwa makhiristo ambewu pakukula kwa kristalo wa safiro. crucible yapamwamba kwambiri ya tungsten imakhala ndi gawo lofunikira pakuwongolera luso la kukoka kwa kristalo, decrystallization kumamatira ku mphika, ndi moyo wautumiki.

Ma tungsten crucibles athu amapanikizidwa kuti apange mawonekedwe, kenako amatenthedwa kutentha kwambiri kuti apange mawonekedwe owundana, ndipo pamapeto pake amapangidwa molondola kuti apange ma tungsten crucibles okhala ndi mphamvu zabwino kwambiri, kukana kutentha, komanso kukhazikika kwamankhwala.

Zindikirani: Mukamagwiritsa ntchito sintered tungsten crucible, muyenera kusamala kuti musasinthe kutentha kwambiri kuti musaphwanye crucible ya sintered tungsten. Kuphatikiza apo, kusamala kuyenera kuchitidwa kuti musagwirizane ndi zinthu zolimba za oxidizing kuti musawononge moyo wautumiki wa sintered tungsten crucible.
