Sirrin "zinariya baƙar fata" a bayan masana'antar semiconductor na photovoltaic: sha'awa da dogaro kan graphite isostatic

Graphite na Isostatic wani abu ne mai matuƙar muhimmanci a fannin photovoltaics da semiconductors. Tare da karuwar kamfanonin graphite na cikin gida cikin sauri, ikon mallakar kamfanonin ƙasashen waje a China ya karye. Tare da ci gaba da bincike da ci gaba mai zaman kansa da kuma ci gaban fasaha, alamun aiki na wasu daga cikin manyan samfuranmu sun yi daidai da ko ma sun fi na masu fafatawa a ƙasashen duniya. Duk da haka, saboda tasirin raguwar farashin kayan masarufi da raguwar farashi daga abokan ciniki masu amfani da shi, farashi ya ci gaba da raguwa. A halin yanzu, ribar kayayyakin cikin gida masu ƙarancin inganci bai kai kashi 20% ba, tare da ci gaba da fitar da ƙarfin samarwa, sabbin matsin lamba da ƙalubale suna tasowa a hankali ga kamfanonin graphite na isostatic.

1. Menene isostatic graphite?

Graphite na Isostatic yana nufin kayan graphite da aka samar ta hanyar matsi na isostatic. Saboda graphite da aka matse ta isostatic ana matse shi daidai gwargwado kuma a hankali ta hanyar matsin ruwa yayin aikin ƙera shi, kayan graphite da aka samar suna da kyawawan halaye. Tun lokacin da aka haife shi a shekarun 1960, graphite na isostatic ya zama jagora a cikin sabbin kayan graphite saboda keɓantattun halaye da kuma nau'ikan aikace-aikace iri-iri.

2. Tsarin samar da graphite na Isostatic

An nuna yadda ake samar da graphite mai matsewa ta hanyar isostatic a cikin hoton. Graphite mai matsewa ta hanyar isotropic yana buƙatar kayan aiki na isotropic na tsari. Ana buƙatar a niƙa kayan aiki zuwa foda mai ƙanƙanta. Ana buƙatar amfani da fasahar matsewa ta Isostatic. Zagayen gasa yana da tsayi sosai. Domin cimma yawan da ake so, ana buƙatar daɗaɗɗen da aka yi amfani da su da kuma zagayowar gasawa. Lokacin graphitization kuma ya fi na graphite na yau da kullun tsayi.

3. Amfani da isostatic graphite

Isostatic graphite yana da amfani iri-iri, galibi a cikin filayen semiconductor da photovoltaic.

A fannin photovoltaics, ana amfani da graphite mai matsewa ta hanyar isostatically a cikin abubuwan graphite a cikin filin zafi na graphite a cikin tanderun girma na silicon crystalline guda ɗaya da kuma a cikin filin zafi na graphite a cikin tanderun silicon polycrystalline. Musamman, maƙallan don samar da kayan silicon polycrystalline, masu rarraba gas don tanderun hydrogenation, abubuwan dumama, silinda masu rufi da masu dumama ingot polycrystalline, tubalan jagora, da bututun jagora don haɓakar kristal guda ɗaya da sauran ƙananan girma. sassa;

A fannin semiconductors, na'urorin dumama da silinda masu rufi don haɓakar lu'ulu'u ɗaya na sapphire na iya amfani da ko dai isostatic graphite ko molded graphite. Bugu da ƙari, wasu abubuwa kamar crucibles, heaters, electrodes, faranti masu kariya daga zafi, da lu'ulu'u iri. Kimanin nau'ikan masu riƙewa 30, tushe don crucibles masu juyawa, faranti masu zagaye daban-daban, da faranti masu nuna zafi an yi su ne da graphite mai matsewa.
