Talooyin ka saarida wasakhda budada garaafka

Qalab graphite waxaa inta badan loo isticmaalaa soo saarista biraha iyo qalabka semiconductor. Si loo sameeyo walxaha birta iyo semiconductor waxay gaaraan nadiif gaar ah oo ay yareeyaan qadarka wasakhda ah, budada graphite oo leh kaarboon sare iyo wasakh hoose ayaa loo baahan yahay. Waqtigaan, waxaa lagama maarmaan ah in laga saaro wasakhda budada graphite inta lagu jiro farsamaynta. Macaamiil badan ma yaqaaniin sida loola tacaalo wasakhda ku jirta budada garaafka. Maanta, Tifaftiraha Furuite Graphite wuxuu ka hadli doonaa talooyinka looga saarayo wasakhda budada garaafka si faahfaahsan:

Marka la soo saaro budada graphite, waa in aan si adag u xakameyno nuxurka wasakhda ah ee xulashada alaabta ceeriin, dooro alaabta ceeriin ee leh maaddada dambaska hooseeya, oo aan ka hortagno kororka wasakhda habka habka budada graphite. Okssaydhyada xubno badan oo wasakh ah ayaa si joogto ah u jajaban oo ay uumi baxaan heerkulka sare, sidaas darteed hubinta nadiifinta budada garaafka ee la soo saaray.

Marka la soo saarayo badeecooyinka garaafyada guud, heerkulka ubucda foornada waxa uu gaaraa ilaa 2300 ℃ iyo waxyaabaha wasakhda ah ee haraaga ahi waa 0.1%-0.3%. Haddii heerkulka xudunta u ah foornada la gaarsiiyo 2500-3000 ℃, waxa ku jira wasakhda haraaga ah aad ayaa loo dhimi doonaa. Marka la soo saarayo alaabada budada garaafiga ah, kookaha batroolka leh ee ka kooban dambaska hooseeya ayaa badanaa loo isticmaalaa walxo iska caabin ah iyo walxaha dahaarka.

Xitaa haddii heerkulka garaafyada si fudud loo kordhiyo ilaa 2800 ℃, wasakhda qaar ayaa weli adag in la saaro. Shirkadaha qaarkood waxay isticmaalaan habab ay ka mid yihiin hoos u dhigista xudunta foornada iyo kordhinta cufnaanta hadda jirta si ay u soo saaraan budada graphite, taas oo yaraynaysa wax soo saarka foornada budada garaafka waxayna kordhisaa isticmaalka awoodda. Sidaa darteed, marka heerkulka foornada budada graphite gaadho 1800 ℃, gaas la sifeeyay, sida chlorine, freon iyo chlorides iyo fluorides, ayaa la soo bandhigaa, waxaana lagu sii wadaa in lagu daro dhowr saacadood ka dib markii ay korontada xumaato. Tani waa si looga hortago wasakhda uumiga leh inay ku faafiso foornada jihada ka soo horjeeda, iyo in laga saaro gaaska la safeeyey ee haray daloolada budada graphite iyadoo la soo bandhigayo xoogaa nitrogen ah.
