Imfihlo "yegolide emnyama" engasemva kweshishini le-semiconductor ye-photovoltaic: umnqweno kunye nokuxhomekeka kwi-graphite ye-isostatic

I-graphite ye-isostatic yinto ebaluleke kakhulu kwi-photovoltaics kunye ne-semiconductors. Ngenxa yokwanda ngokukhawuleza kweenkampani ze-graphite ze-isostatic zasekhaya, ukuzimela kweenkampani zangaphandle eTshayina kuye kwaphulwa. Ngenxa yophando oluzimeleyo oluqhubekayo kunye nophuhliso kunye nophuhliso lwetekhnoloji, izalathisi zokusebenza kwezinye zeemveliso zethu eziphambili zilingana okanye zingcono kunezo zabakhuphisana nabo bamazwe ngamazwe. Nangona kunjalo, ngenxa yempembelelo ephindwe kabini yokuhla kwamaxabiso ezinto eziluhlaza kunye nokunciphisa iindleko ngabathengi bokugqibela, amaxabiso aqhubekile nokuhla. Okwangoku, inzuzo yeemveliso zasekhaya ezikumgangatho ophantsi ingaphantsi kwama-20%. Ngokukhutshwa rhoqo kwamandla emveliso, uxinzelelo olutsha kunye nemingeni iziswa kancinci kancinci kwiinkampani ze-graphite ze-isostatic.

1. Yintoni i-isostatic graphite?

I-graphite e-isostatic ibhekisa kwizinto ze-graphite eziveliswa ngokucinezela i-isostatic. Ngenxa yokuba i-graphite ecinezelwe i-isostatic icinezelwa ngokulinganayo nangokuthe ngcembe luxinzelelo lolwelo ngexesha lenkqubo yokubumba, izinto ze-graphite eziveliswayo zineempawu ezintle kakhulu. Ukusukela ekuzalweni kwayo ngeminyaka yoo-1960, i-graphite e-isostatic ibe yinkokeli phakathi kwezinto ezintsha ze-graphite ngenxa yeempawu zayo ezikhethekileyo kunye noluhlu olubanzi lwezicelo.

2. Inkqubo yokuvelisa i-graphite e-isostatic

Ukuhamba kwenkqubo yokuvelisa i-graphite ecinezelweyo ngokuyi-isostatic kuboniswe kumfanekiso. I-graphite e-isostatic ifuna izinto eziluhlaza ezi-isotropic ngokwesakhiwo. Izinto eziluhlaza kufuneka zicolwe zibe yimipuphu ecolekileyo. Itekhnoloji yokubumba i-isostatic pressing kufuneka isetyenziswe. Umjikelo wokosa mde kakhulu. Ukuze kufezekiswe uxinano olujoliswe kulo, kufuneka imijikelo emininzi yokufunxa kunye nokusa. , ixesha le-graphitization nalo lide kakhulu kunele-graphite eqhelekileyo.

3. Ukusetyenziswa kwe-graphite ye-isostatic

I-graphite ye-isostatic ineendlela ezininzi zokusetyenziswa, ikakhulu kwiinkalo ze-semiconductor kunye ne-photovoltaic.

Kwicandelo le-photovoltaics, i-graphite ecinezelweyo ngokwe-isostatic isetyenziswa kakhulu kwiinxalenye ze-graphite kwintsimi yobushushu be-graphite kwii-ovens zokukhula kwe-silicon yekristale enye nakwintsimi yobushushu be-graphite kwii-ovens ze-silicon ye-polycrystalline. Ngokukodwa, ii-clamps zokuvelisa izinto ze-silicon ye-polycrystalline, abasasazi begesi kwii-ovens ze-hydrogenation, izinto zokufudumeza, ii-cylinders ze-insulation kunye nee-heaters ze-ingot ze-polycrystalline, iibhloko zesikhokelo, kunye neetyhubhu zesikhokelo zokukhula kwe-crystal enye kunye nezinye iindawo ezincinci.

Kwicandelo lee-semiconductors, ii-heaters kunye nee-insulation cylinders ze-sapphire single crystal growth zingasebenzisa i-isostatic graphite okanye i-molded graphite. Ukongeza, ezinye izinto ezifana nee-crucibles, ii-heaters, ii-electrodes, ii-heat-insulating shielding plates, kunye nee-seed crystals. Malunga neentlobo ezingama-30 zezibambi, iziseko zee-crucibles ezijikelezayo, ii-circular plates ezahlukeneyo, kunye nee-heat reflection plates zenziwe nge-graphite ecinezelweyo ngokwe-isostatically.
