Physical and Chemical Properties ofSic Crucibles
Thaum xaiv cov crucibles rau cov ntawv thov kev lag luam, kev nkag siab txog lub cev thiab tshuaj indexes yog qhov tseem ceeb. Hauv qab no yog ib qho kev tawg ntawm cov khoom tseem ceeb ntawm ISO Hom Sic Crucibles:
| Lub cev muaj zog | Index |
|---|---|
| Refractoriness | ≥1650 ° C |
| Pom tseeb Porosity | ≤ 20% |
| Kev ceev ceev | ≥ 2.2 g / cm² |
| Crushing zog | ≥8.5 MPa |
| Tshuaj muaj pes tsawg leeg | Index |
|---|---|
| Cov ntsiab lus carbon (C%) | 20-30% |
| Silicon Carbide (SiC%) | 50-60% |
| Alumina (AL2O3%) | 3-5% |
Cov yam ntxwv no muab Sic Crucibles tshwj xeeb thermal conductivity, tsis tshua muaj thermal expansion, thiab tsis kam mus rau tshuaj lom neeg corrosion, xyuas kom meej tias lawv ua tau zoo nyob rau hauv txawm lub harshest ib puag ncig.

Qhov zoo ntawm Sic Crucibles
- Kub-kub Resistance: Sic Crucibles tiv taus qhov kub txog li 1650 ° C, ua rau lawv zoo tagnrho rau cov hlau yaj thiab lwm yam kev siv cua sov.
- Durability thiab Longevity: Nrog lub zog crushing muaj zog ntawm ≥ 8.5 MPa, cov crucibles no tuaj yeem tiv taus cov neeg kho tshuab kev ntxhov siab koom nrog hauv cov chaw lag luam yam tsis muaj kev tawg lossis deforming.
- Tshuaj Stability: Cov ntsiab lus ntawm silicon carbide siab (50-60%) muaj cov tshuaj tiv thaiv zoo heev, ua kom lub neej ntev txawm tias raug molten hlau lossis tshuaj lom neeg.
Kev nyab xeeb thiab kev saib xyuas ntawm Sic Crucibles
Txhawm rau txuas ntxiv lub neej ntawm Sic Crucibles thiab ua kom lawv txoj haujlwm nyab xeeb, nws yog ib qho tseem ceeb uas yuav tsum ua raws li ob peb txoj kev saib xyuas:
- Kev ntxuav tu tsis tu ncua: Crucibles yuav tsum tau ntxuav tsis tu ncua kom tshem tawm cov khoom seem, tiv thaiv kev sib kis thiab corrosion.
- Tsis txhob Thermal Shock: Maj mam cua sov thiab txias yog qhov tseem ceeb los tiv thaiv kev tawg. Kev hloov kub tam sim ntawd tuaj yeem ua rau cov khoom tawg.
- Tiv thaiv cov tshuaj tiv thaiv corrosion: Tsis txhob raug cov tshuaj corrosive, tshwj xeeb tshaj yog alkaline lossis acidic daws, uas tuaj yeem degrade lub crucible qhov kev ncaj ncees.
Kev Paub Txog Tswv Yim rau Cov Neeg Yuav Khoom
Kev xaiv txoj cai Sic Crucible nyob ntawm qhov xav tau tshwj xeeb ntawm koj cov txheej txheem kev lag luam. Xav txog yam xws li qhov kub thiab txias, cov khoom siv sib xws, thiab qhov xav tau loj. Hauv kev siv tiag tiag hauv ntiaj teb, ntau tus neeg yuav khoom tau tshaj tawm qhov txo qis hauv kev saib xyuas tus nqi thiab nce kev ua tau zoo los ntawm kev hloov mus rau Sic Crucibles.
Sic Crucibles yog ib qho cuab yeej tseem ceeb rau kev lag luam uas xav tau cov ntaub ntawv ua tau zoo uas muaj peev xwm tiv taus qhov kub thiab txias thiab raug tshuaj lom neeg. Los ntawm kev nkag siab txog lawv cov khoom thiab ua raws li kev saib xyuas kom raug, cov lag luam tuaj yeem txhim kho kev ua haujlwm zoo thaum txo qis sijhawm.
