Ukuqina kobuso be-flake graphite kuncane, akukho sici endaweni enkulu, futhi kunezinhlanganisela eziphilayo ezingaba ngu-0.45% eziguquguqukayo ebusweni be-flake graphite, konke lokhu kunciphisa ukumanzi kwe-flake graphite. Ukungathandi amanzi okuqinile ebusweni be-flake graphite kwenza kube kubi ukugeleza kwe-castable, futhi i-flake graphite ivame ukuhlangana kunokuba ihlakazeke ngokulinganayo endaweni ephikisayo, ngakho-ke kunzima ukulungiselela i-amorphous refractory efanayo neqinile. Uchungechunge oluncane olulandelayo lokuhlaziywa kwe-Furuite graphite kokumanzi kanye nemikhawulo yokusetshenziswa kwe-flake graphite:
I-graphite ye-Flake
Isakhiwo esincane kanye nezakhiwo ze-flake graphite ngemva kokusha kwezinga lokushisa eliphezulu kunqunywa kakhulu ukumanziswa koketshezi oluyi-silicate olusezingeni lokushisa eliphezulu ku-flake graphite. Lapho kumanziswa, isigaba soketshezi oluyi-silicate ngaphansi kwesenzo samandla e-capillary, singene esikhaleni sezinhlayiya, ngokunamathelana phakathi kwazo ukuze kuhlanganiswe izinhlayiya ze-flake graphite, ekwakhekeni kwengqimba yefilimu ezungeze i-flake graphite, ngemva kokupholisa ukuze kwakheke i-continuum, kanye nokwakheka kwe-interface yokunamathela okuphezulu ne-flake graphite. Uma lezi ezimbili zingamanziswanga, izinhlayiya ze-flake graphite zakha ama-aggregates, kanti isigaba soketshezi oluyi-silicate sivalelwe esikhaleni sezinhlayiya futhi sakhe umzimba ohlukanisiwe, okunzima ukwakha i-complex exinene ngaphansi kwezinga lokushisa eliphezulu.
Ngakho-ke, i-Furuite graphite yaphetha ngokuthi ukumanzi kwe-flake graphite kumele kuthuthukiswe ukuze kulungiselelwe izinto ezinhle kakhulu zokungaqini kwekhabhoni.
