2) Dangane da ci gaban samfura, kasashen waje sun mai da hankali sosai ga ci gaban mai-kyau, mai-girma, zane-zanen isotropic azaman mai zane-zane na ci gaba. Musamman, kamfanin Linsdorf na Jamusawa ya sami ƙwarewar kwarewa a wannan yanki kuma ya ɗauki matakai da yawa. Kamfanin Toyo Tansuo na Japan shima yana ci gaba, kuma yana da damar wucewa. A kasar Sin, Dongshin Carbon Plant da Carbon Shuba Carbon Shuba sun yi nasara a wannan yanki 'yan shekarun da suka gabata. Don inganta aikin aikin farfajiyar ƙarafa, ana amfani da fasahar rufe farfajiya, wanda ke da tasiri mafi girma kan haɓaka rayuwar sabis na ci gaba da jefa ƙira. Tarayyar Soviet ta karɓi fasahar narkar da sinadarin boron nitride, yayin da zanen ci gaba da zana zane a cikin ƙasata galibi an adana shi ne. Kodayake ba a yadu da shi ba, yawancin masu amfani sun yi marhabin da shi. Bugu da kari, kamfanin samar da wutar lantarki na Shanghai shima yana amfani da tsari na gargajiya don kara 0.6 zuwa 2% na karafan karfe, kuma yana amfani da aikin wadannan karafan karfe don canzawa zuwa babban carbides mai narkewa a 2500 ℃ mai zafin jiki mai fasaltawa, don haka inganta haɓakar iskar shaka na ci gaba da zaben 'yan wasa graphite. Don cimma manufar inganta rayuwar sabis.
3) A manyan sikelin-bayani na ci gaba da simintin jadawalin graphite ya zama babban fifiko. Ganin cewa ingancin babban siket din zane mai zane yana da babban rata idan aka kwatanta shi da kasashen waje, ya kamata ayi kokarin bunkasa shi. Wannan ya cancanci kulawa da masana'antun da suka dace, duka dangane da fa'idodin zamantakewa da tattalin arziki.
4) A cikin kasata, fasahar ci gaba da aikin simintin gyare-gyare na bayanan martaba na jan ƙarfe ya haɓaka cikin sauri, an fara shi a baya, yana da girma, kuma yana da ƙwarewa da wadatacciyar ƙwarewa. A ci gaba da zaben 'yan wasa na simintin gyaran kafa bayanan martaba sabon ci gaba ne, kuma ana buƙatar ci gaba da fasahar yin simintin gyare-gyare Duk da cewa har yanzu ana iya amfani da jifa jifa, ci gaba da haɓakawa ya zama dole.
5) Bincike ya kamata a gudanar don inganta ƙirar ƙira na ci gaba da yin simintin gyare-gyaren zane da inganta tsarin samfur. Wannan ma ɗayan matakan ne na inganta rayuwar mai ƙirar ƙaramin hoto. Jamus da Tarayyar Soviet suna da cikakkun buƙatu don ƙera kayan aikin ƙira, kuma masu amfani da gida suna fatan cewa za a iya inganta ƙwanƙolin bango na ciki na ci gaba da yin zane-zane, wanda zai iya hana ɓarkewa a saman simintin gyaran. Bugu da kari, domin inganta yanayin lambar sadarwa. Yakamata a inganta sifa da sifa ta ci gaba da yin simintin gyare-gyare na zana jifa don yankin tuntuɓar juna da jan karfe ya kai kashi 80%.
