Cov khoom zoo tshaj plaws rau tus ntoo khaubliag?

Nyob rau hauv lub realm ntawm metallgy, chemistry, thiab cov khoom kev tshawb fawb, kev xaiv ntawm txoj cairoob ntooCov khoom siv yog qhov tseem ceeb hauv kev txiav txim siab ntawm ntau yam txheej txheem, xws li los ntawm cov hlau siab ua ke rau cov synthesis ntawm kev tshaj lij ceramics thiab tsom iav. Muaj ob peb cov ntaub ntawv crucible muaj, txhua tus nrog nws cov cim ntawm cov khoom thiab cov txiaj ntsig. Cia tshawb cov ntaub ntawv zoo tshaj plaws rau cov crucibles hauv cov ncauj lus ntau dua:

 

Quartz CruciBles

 Quartz crucailes, feem ntau ua los ntawm high-purity fused silica, muaj npe rau lawv cov txiaj ntsig tshwj xeeb. Lawv excel hauv kev tawm tsam ntau kub, nrog cov kev cuam tshuam ntawm cov kua qaub thiab cov hauv paus, thiab tswj kev ruaj khov nyob rau hauv cov mob thermal. Cov crucails no pom lawv cov niche kom melting high-purity hlau xws li silicon, txhuas, thiab hlau. Tsis tas li ntawd, lawv cov thermal zoo tshaj capestivity txhim kho melting efficiency. Txawm li cas los xij, tus hwm zoo ntawm Quartz tuaj ntawm tus nqi siab dua.

 

Ceramic crucailes

Ceramas crucibles encompass nyob rau ob pawg loj: aluminium oxide ceramics thiab zirconium oxide ceramics. Cov crucailes muaj cov kub ua kom zoo thiab tshuaj lom neeg ruaj khov, ua rau lawv cov khoom siv vertive, suav nrog cov khoom siv dav, nrog rau cov hlau, iav, ceramics, thiab lwm yam. Txawm li cas los xij, lawv cov kev tawm tsam kub yog qhov qis dua li ntawm Quartz cruciBles, uas ua rau lawv muaj ntau dua rau cov ntaub ntawv nrog cov ntsiab lus melting hauv qab 1700 ° C.

 

Graphite shregles

Graphacite cross yog cov haujlwm ntawm cov kev ua haujlwm siab, feem ntau ua cov cuab yeej tseem ceeb hauv kev tshawb fawb thiab kev tshawb fawb tshuaj lom neeg. Cov crucailes no muaj nyob rau hauv ob daim ntawv thawj: ntuj graphite thiab hluavtaws graphite. Ntuj Graphite crucibles khav theeb Thiaj ua phem rau SuperStance thiab corrosion tsis ruaj khov thiab corrosion tsis kam, zoo tagnrho rau ntau qhov kev siv kub-kub. Ntawm qhov tod tes, hluavtaws graphite cruciles yog tus nqi-ua tau zoo tab sis yuav muaj me ntsis kev ruaj khov thiab corrosion tsis kam.

 

Hlau CruciBles

Hlau cruciles tau tsim los ntawm cov ntaub ntawv xws li stainless hlau, molybdenum, platinum, thiab ntau dua. Lawv yog tus mus rau kev xaiv thaum cuam tshuam nrog cov ntaub ntawv nrog cov ntsiab lus zoo melting lossis thaum ntsib nrog cov kua qaub heev lossis alkaline. Hlau crucibles ua rau muaj zog tiv thaiv rau corrosion thiab tswj hwm zoo kawg li thermal ruaj khov. Txawm li cas los xij, lawv siv yog txuam nrog tus nqi siab dua piv rau lwm cov ntaub ntawv Crucible.

TNws xaiv cov khoom crucible yuav tsum tau tsav los ntawm cov ntaub ntawv tshwj xeeb tau ua tiav thiab nthuav tawm cov xwm txheej. Txhua hom Crucible muaj nws cov tshwj xeeb zoo thiab kev xaiv qhov tseem ceeb hauv kev ua tiav Metallurgy, Chemistry, thiab cov khoom kev tshawb fawb.
