Khoom siv
Peb lub chaw soj nstuam crucibles yog tsim los ntawm high-purity silica (SiO₂), cov khoom siv dav paub txog nws cov thermal thiab tshuaj lom neeg zoo:

Purity: Peb cov crucibles yog tsim los ntawm 45% ntshiab silica, uas ua kom muaj kev tiv thaiv rau impurities, tswj kev ncaj ncees ntawm koj cov kev sim thiab kev sim.
High Melting Point: Nrog lub melting point ntawm 1710 ° C, silica yog zoo tagnrho rau cov ntawv thov uas yuav tsum tau ua hauj lwm nrog kub heev. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov chaw soj nstuam ua cov kev sim ntawm cov hlau, ceramics, thiab cov ntaub ntawv refractory.
Tsawg Thermal Expansion: Qhov qis coefficient ntawm thermal expansion txo qhov kev pheej hmoo ntawm kev tawg nyob rau hauv cov cua kub ceev los yog cua txias, ua rau lub crucible zoo nyob rau hauv fluctuating thermal ib puag ncig.

Thermal thiab Mechanical Performance
Qhov chaw kuaj mob feem ntau raug crucibles rau qhov kub thiab txias. Peb cov silica crucibles ua tau zoo hauv kev tswj kev ruaj ntseg ntawm qhov kub txog li 1600 ° C, uas ua rau lawv zoo heev rau kev siv xws li:

Hlau Melting thiab Smelting: Tsim nyog rau tuav cov hlau molten xws li tooj liab (melting point: 1085 ° C), qhov tseeb ntawm kev tswj qhov kub thiab txias yog qhov tseem ceeb.
Kev Ntsuas Kub Kub: Zoo tagnrho rau cov txheej txheem xws li kev txheeb xyuas qhov sib txawv thermal (DTA) lossis qhov sib txawv scanning calorimetry (DSC), qhov twg cov khoom siv ruaj khov ntawm qhov kub thiab txias yog qhov tseem ceeb.
Ua tsaug rau lawv cov thermal shock tsis kam, cov crucibles no tuaj yeem tiv taus qhov kub thiab txias hloov pauv yam tsis muaj deforming lossis tawg, ua rau lawv zoo meej rau cov txheej txheem kuaj uas xav tau cua sov thiab cua txias.

Ua tsaug rau lawvthermal shock kuj, cov crucibles no tuaj yeem ua siab ntevkub hloov ceevtsis deforming los yog tawg, ua rau lawv zoo meej rau kev kuaj cov txheej txheem uas yuav tsum tau cua sov thiab cua txias.

Chemical Resistance thiab Stability

Silica crucibles muajsuperior tshuaj inertness, uas yog ib qho tseem ceeb thaum ua hauj lwm nrog reactive hlau, corrosive tshuaj, los yog molten oxides. Cov crucibles tiv cov tshuaj tiv thaiv nrog feem ntau cov acids thiab cov hauv paus, suav nrogalkalisthiabhlau oxides, xyuas kom meej tias koj cov txiaj ntsig kev sim nyob twj ywm tsis muaj paug.

• Corrosion Resistance: Silica tsis kam rau oxidation thiab corrosion ua kom ntseeg tau tias lub crucible nto tsis degrade txawm tias thaum raug cov khoom hnyav.
• Purity Maintenance: Cov tshuaj lom neeg ruaj khov ntawm fused silica khaws cov purity ntawm cov qauv raug kuaj, tseem ceeb heev rau kev siv tshuaj ntsuam xyuas thiab cov ntaub ntawv tshawb fawb.
