Qhov sib txawv ntawm Silicon Carbide Crucibles thiab Graphite Crucibles

Qhov sib txawv ntawm Silicon Carbide Crucibles thiab Graphite Crucibles

Silicon carbide cruciblesthiab graphite crucibles feem ntau yog siv cov thawv kub kub hauv chav kuaj thiab chaw tsim khoom. Lawv nthuav tawm qhov sib txawv tseem ceeb hauv cov khoom siv, lub neej ntev, tus nqi, qhov siv tau, thiab kev ua haujlwm. Nov yog cov ncauj lus kom ntxaws sib piv los pab xaiv qhov tsim nyog crucible rau cov kev xav tau tshwj xeeb:

1. Khoom siv:

• Silicon Carbide Crucibles: Feem ntau yog tsim los ntawm cov ntaub ntawv silicon carbide, cov crucibles no muaj kev tiv thaiv kub kub thiab corrosion kuj. Lawv ua tau zoo rau cov txheej txheem xws li sintering, kho cua sov, thiab siv lead ua loj hlob ntawm cov hlau thiab ceramics.
• Graphite Crucibles: Feem ntau crafted los ntawm ntuj flake graphite, tseem hu ua graphite av nplaum crucibles, lawv nrhiav kev siv nyob rau hauv kev kho cua sov thiab siv lead ua loj hlob ntawm ob qho tib si metallic thiab non-metallic cov ntaub ntawv.

2. Lifespan:

• Graphite Crucibles: Cov txheeb ze rau silicon carbide crucibles, graphite crucibles muaj lub neej ntev, feem ntau yog li ntawm peb mus rau tsib npaug ntawm silicon carbide crucibles.

3. Nqe:

• Silicon Carbide Crucibles: Vim yog cov txheej txheem tsim khoom thiab cov nqi khoom, silicon carbide crucibles feem ntau raug nqi siab dua piv rau graphite crucibles. Txawm li cas los xij, hauv qee qhov kev siv, lawv qhov kev ua tau zoo tshaj plaws tuaj yeem ua pov thawj tus nqi sib txawv.

4. Siv tau ntau yam:

• Silicon Carbide Crucibles: Ntxiv rau qhov tsim nyog rau kev ua cov hlau thiab cov ceramics, silicon carbide crucibles kuj tseem siv tau hauv cov khoom siv hluav taws xob thiab optoelectronics.
• Graphite Crucibles: Haum rau ntau yam khoom siv hlau thiab tsis yog xim hlau hauv kev kho cua sov thiab cov txheej txheem siv lead ua.

5. Kev ua tau zoo sib txawv:

• Graphite Crucibles: Nrog rau qhov ceev ntawm kwv yees li 1.3 kg / cm², sab hauv thiab sab nraud qhov sib txawv ntawm ib ncig ntawm 35 degrees, thiab kuj tsis zoo rau acid thiab alkali corrosion, graphite crucibles yuav tsis muab lub zog txuag piv rau silicon carbide crucibles.
• Silicon Carbide Crucibles: Nrog rau qhov ceev ntawm 1.7 mus rau 26 kg / mm², qhov kub thiab txias ntawm qhov sib txawv ntawm 2-5 degrees, thiab kev ua haujlwm zoo rau cov kua qaub thiab alkali corrosion, silicon carbide crucibles muab lub zog txuag ntawm ib ncig ntawm 50%.

Xaus:

Thaum xaiv ntawm silicon carbide thiab graphite crucibles, cov kws tshawb fawb yuav tsum xav txog cov kev xav tau ntawm kev sim, kev txwv nyiaj txiag, thiab kev ua haujlwm xav tau. Silicon carbide crucibles ua tau zoo nyob rau hauv high-temperature thiab corrosive ib puag ncig, thaum graphite crucibles muaj qhov zoo ntawm cov nqi-zoo thiab dav siv tau. Los ntawm kev nkag siab txog qhov sib txawv no, cov kws tshawb fawb tuaj yeem txiav txim siab kom paub tseeb tias cov txiaj ntsig zoo hauv lawv qhov kev sim.
