Intshayelelo yokhetho lwe-crucible ye iziko lombane lokulinga

Isithando sombane sombane sebhubhoratri singasebenzisa i-high-purity corundum crucibles, i-quartz crucibles, kunye ne-quartz-containing zirconium crucibles, kunye neentlobo ezahlukeneyo ziya kukhethwa ngokwezinto ezahlukeneyo kunye namaqondo okushisa ahlukeneyo.

1. I-Corundum crucible

I-corundum crucible yenziwe nge-alumina ene-porous fused, eyomeleleyo kwaye iyamelana nokunyibilika. Ilungele ukunyibilika iisampulu ngezinto ezibuthathaka zealkaline ezifana ne-anhydrous sodium carbonate njenge-flux, kodwa ayifanelekanga kwizinto ezinamandla zealkaline ezifana ne-sodium peroxide kunye nezinto ezine-acidic njenge-flux. Nyibilikisa isampuli.

2. I-quartz crucible

I-Quartz crucible ingasetyenziselwa ngaphantsi kwe-1650 degrees, ihlulwe ibe yinto ecacileyo kunye ne-opaque. I-semi-transparent quartz crucible eyenziwe yindlela ye-arc yombane isetyenziselwa ukuzoba i-silicon yobubanzi obukhulu, into eyimfuneko esisiseko kuphuhliso lweesekethe ezinkulu ezidibeneyo. Namhlanje, amazwe aphuhlileyo kwishishini le-semiconductor emhlabeni asebenzise le crucible ukuthatha indawo ye-quartz crucible encinci ecacileyo. Ineenzuzo zokucoceka okuphezulu, ukumelana nobushushu obuqinileyo, ubungakanani obukhulu, ukuchaneka okuphezulu, ukugcinwa kobushushu obuhle, ukonga amandla, umgangatho ozinzile njalo njalo.
