Carbon-carbon crucibles yog tsuas yog siv nyob rau hauv thermal teb systems xws li photovoltaic thiab semiconductor siv lead ua kev loj hlob rauv.
Lawv lub luag haujlwm tseem ceeb yog:
1. High-temperature bearing muaj nuj nqi:Lub quartz crucible ntim nrog polysilicon raw khoom yuav tsum tau muab tso rau hauv cov pa roj carbon / carbon crucible. Cov pa roj carbon / carbon crucible yuav tsum dais qhov hnyav ntawm quartz crucible thiab polysilicon raw cov ntaub ntawv los xyuas kom meej tias cov ntaub ntawv raw yuav tsis xau tawm tom qab high-temperature quartz crucible softens. Tsis tas li ntawd, cov khoom siv raw yuav tsum tau nqa los tig thaum lub sij hawm siv lead ua rub. Yog li ntawd, cov khoom siv kho tshuab yuav tsum muaj qhov siab;
2. Thaum tshav kub kub hloov ua haujlwm:Lub crucible ua cov cua kub uas yuav tsum tau rau melting ntawm polysilicon raw cov ntaub ntawv los ntawm nws tus kheej zoo thermal conductivity. Lub melting kub yog hais txog 1600 ℃. Yog li ntawd, lub crucible yuav tsum muaj zoo high-temperature thermal conductivity;
3. Kev nyab xeeb muaj nuj nqi:Thaum lub qhov cub raug kaw thaum muaj xwm txheej ceev, lub crucible yuav raug kev nyuaj siab nyob rau hauv lub sij hawm luv luv vim lub ntim expansion ntawm polysilicon thaum txias (kwv yees li 10%).
Cov yam ntxwv ntawm VET Energy's C / C crucible:
1. High purity, tsawg volatility, tshauv ntsiab lus <150ppm;
2. Kev kub siab ua haujlwm, lub zog tuaj yeem khaws cia txog 2500 ℃;
3. Kev ua tau zoo heev xws li corrosion kuj, hnav tsis kam, acid thiab alkali tsis kam;
4. Tsawg thermal expansion coefficient, muaj zog tiv thaiv thermal shock;
5. Cov khoom siv hluav taws xob kub zoo, lub neej ua haujlwm ntev;
6. Kev siv lub tswv yim tsim tag nrho, siab zog, qauv yooj yim, lub teeb yuag thiab ua haujlwm yooj yim.
