Tungsten Crucible Description
Tungsten crucible yog cov khoom siv tseem ceeb siv hauv cov ntawv thov hais txog kev loj hlob ntawm sapphire siv lead ua, lub tshuab nqus tsev vacuum thiab tsis tshua muaj lub ntiaj teb metallurgy. Peb cov tungsten crucibles raug cais raws li forged los yog pressed-sintered crucibles, nyob ntawm seb lawv yog fabricated li cas. Peb cov tungsten crucibles muaj qhov tshwj xeeb hloov pauv, du nto, siab purity, thiab muaj zog creep kuj.
Tungsten crucible yog dav siv nyob rau hauv technologies rau loj hlob monocrystals los ntawm molten corundum. Nws kuj yog siv nyob rau hauv electronics thiab technologies rau thermal vaporization - deposition ntawm ntau yam khoom. Tungsten crucible yog ib qho tseem ceeb hauv qhov cub kub kub ua rau nws lub siab melting point.
SSC tshwj xeeb hauv kev muab txhua yam ntawm tungsten crucibles xws li crucible nrog hau, round crucible, tapered crucible, customized square & rectangular crucible. Peb kuj muab cov khoom siv hlau ntshiab xws li lub tshuab cua sov, lub tshuab hluav taws xob hluav taws xob, cov ntawv, kev txhawb nqa, thiab lwm yam. Cov khoom no tuaj yeem siv rau hauv cov txheej txheem ntawm sapphire kev loj hlob thiab tsawg-lub ntiaj teb melting.
