Cadaadiska dusha sare ee garaafiga flake waa yar yahay, ma jirto wax cillad ah oo ku yaal aag weyn, waxaana jira qiyaastii 0.45% xeryahooda organic kacsan ee dusha sare ee graphite flake, kuwaas oo dhamaantood ka sii daraya qoynta graphite flake. Hydrophobicity xooggan ee dusha sare ee garaafiga flake waxay ka sii daraysaa dareeraha la tuuri karo, iyo graphite flake waxay u janjeertaa inay isku ururiso halkii ay si siman ugu firdhi lahayd refractory, markaa way adagtahay in la diyaariyo direyska iyo cufan refractory amorphous ah. Taxanahan yar ee soo socda ee falanqaynta garaafka Furuite ee qoynta iyo xaddidaadaha codsiga ee garaafiga flake:
Garaafka caleen
Qaab-dhismeedka yar-yar iyo sifooyinka graphite flake ka dib sintering heerkulka sare waxaa inta badan lagu go'aamiyaa qoynta ee dareeraha silicate heerkulka sare si ay u jajabiyaan graphite. Marka qoynta, silicate wajiga dareere hoos fal ee xoogga capillary, galay farqiga qayb qayb, by adhesion iyaga u dhexeeya si ay u xidhi qayb ka graphite flake, in formation of lakabka ah ee filimka agagaarka graphite flake ka dib qaboojinta si ay u sameeyaan joogto ah, iyo samaynta interface adhesion sare leh graphite flake. Haddii labada aan la qoyan, qayb ka graphite flake sameeyaan wadar ah, iyo heerka dareere silicate waxa uu ku kooban yahay farqiga u qayb ka mid ah oo sameeyo jirka go'doonsan, taas oo ay adag tahay in la sameeyo isku dhafan cufan hoos heerkulka sare.
Sidaa darteed, Furuite graphite waxay soo gabagabaysay in qoynta graphite flake ay tahay in la hagaajiyo si loo diyaariyo refractories kaarboon aad u fiican.
