Sirta "dahabka madow" ee ka dambeysa warshadaha semiconductor-ka sawir-qaadista: rabitaanka iyo ku tiirsanaanta garaafka isostatic

Graphite-ka Isostatic waa walax aad muhiim ugu ah sawir-qaadayaasha iyo semiconductors-ka. Iyadoo ay si xawli ah u korayaan shirkadaha garaafitka isostatic-ka ee gudaha, kali-talisnimada shirkadaha shisheeye ee Shiinaha ayaa jabtay. Iyadoo cilmi-baaris iyo horumarin madax-bannaan oo joogto ah iyo horumarro tignoolajiyadeed, tilmaamayaasha waxqabadka qaar ka mid ah alaabtayada asaasiga ah waxay la mid yihiin ama ka fiican yihiin kuwa tartamayaasha caalamiga ah. Si kastaba ha ahaatee, sababtoo ah saameynta laba-geesoodka ah ee hoos u dhaca qiimaha alaabta ceeriin iyo hoos u dhaca kharashka macaamiisha isticmaalaha dhammaadka ah, qiimuhu wuu sii socday inuu hoos u dhaco. Waqtigan xaadirka ah, faa'iidada alaabada hoose ee gudaha ayaa ka yar 20%. Iyadoo si joogto ah loo sii daayo awoodda wax soo saarka, cadaadisyo iyo caqabado cusub ayaa si tartiib tartiib ah loogu keenayaa shirkadaha garaafitka isostatic.

1. Waa maxay isostatic graphite?

Graphite-ka Isostatic waxaa loola jeedaa walxaha garaafiga ee lagu soo saaro cadaadiska isostatic. Sababtoo ah garaafiga si gooni gooni ah loo cadaadiyo si isku mid ah oo joogto ah ayaa cadaadis loogu saaraa cadaadiska dareeraha inta lagu jiro habka wax lagu sameeyo, walxaha garaafiga ee la soo saaray waxay leeyihiin sifooyin aad u fiican. Tan iyo markii la dhashay 1960-meeyadii, garaafiga isostatic wuxuu noqday hormuud ka ah walxaha garaafiga cusub sababtoo ah sifooyinkiisa gaarka ah iyo codsiyada ballaaran.

2. Habka wax soo saarka garaafka Isostatic

Socodka habka wax soo saarka ee graphite-ka si gooni ah loo riixay ayaa lagu muujiyay sawirka. Graphite-ka Isostatic wuxuu u baahan yahay walxo cayriin ah oo qaab-dhismeed ahaan isotropic ah. Alaabada ceeriin ah waa in lagu shiido budo khafiif ah. Tiknoolajiyadda wax lagu dhejiyo ee cadaadiska Isostatic ayaa loo baahan yahay in la isticmaalo. Wareegga dubista waa mid aad u dheer. Si loo gaaro cufnaanta bartilmaameedka, waxaa loo baahan yahay wareegyo badan oo lagu shubo iyo dubista. Muddada garaafka ayaa sidoo kale aad uga dheer tan garaafka caadiga ah.

3. Codsiga garaafka isostatic

Graphite Isostatic wuxuu leeyahay codsiyo kala duwan, inta badan goobaha semiconductor-ka iyo photovoltaic.

Dhinaca photovoltaics-ka, graphite-ka si gooni gooni ah loo riixay waxaa inta badan loo isticmaalaa qaybaha graphite-ka ee ku jira goobta kulaylka graphite ee foornada koritaanka silicon-ka keli ah iyo goobta kulaylka graphite ee foornooyinka silicon-ka ee polycrystalline. Gaar ahaan, qalabka lagu xiro wax soo saarka walxaha silicon-ka ee polycrystalline, qaybiyeyaasha gaaska ee foornada hydrogenation-ka, walxaha kululaynta, dhululubada dahaarka iyo kuleyliyeyaasha polycrystalline, baloogyada jihada, iyo sidoo kale tuubooyinka hagitaanka ee koritaanka kiristaalka keli ah iyo cabbirro kale oo yaryar.

Dhinaca semiconductors-ka, kuleyliyeyaasha iyo dhululubada dahaarka ee koritaanka kiristaalka hal sapphire waxay isticmaali karaan graphite isostatic ama graphite la qaabeeyey. Intaa waxaa dheer, qaybaha kale sida gogosha, kuleyliyeyaasha, elektroodhada, saxannada ilaalinta kulaylka, iyo kiristaallada abuurka Qiyaastii 30 nooc oo haystayaal ah, saldhigyo loogu talagalay gogosha wareegaysa, saxanno wareegsan oo kala duwan, iyo saxannada milicsiga kulaylka ayaa laga sameeyay graphite oo si gooni gooni ah loo riixay.
