Graphite allotrope ne na carbon, wani lu'ulu'u ne mai canzawa tsakanin lu'ulu'u na atomic, lu'ulu'u na ƙarfe da lu'ulu'u na kwayoyin halitta. Gabaɗaya launin toka baƙi ne, laushi mai laushi, jin mai mai. Ƙarfafa zafi a cikin iska ko iskar oxygen wanda ke ƙonewa da samar da carbon dioxide. Masu ƙarfi na oxidizing za su yi oxidize shi zuwa acid na halitta. Ana amfani da shi azaman wakilin hana sakawa da kayan shafawa, yin crucible, electrode, busasshen baturi, gubar fensir. Ikon gano graphite: graphite na halitta, graphite mai yawa na crystalline, flake graphite, graphite cryptocrystalline, foda graphite, takarda graphite, graphite mai faɗi, emulsion graphite, graphite mai faɗi, graphite mai faɗi, graphite mai yumbu da foda graphite mai sarrafawa, da sauransu.
1. juriya ga zafin jiki mai yawa: wurin narkewar graphite shine 3850±50℃, koda bayan ƙonewar baka mai zafi sosai, asarar nauyi ƙarami ne, ma'aunin faɗaɗa zafi ƙarami ne. Ƙarfin graphite yana ƙaruwa tare da ƙaruwar zafin jiki. A 2000℃, ƙarfin graphite yana ninkawa.
2. ƙarfin watsawa da kuma ƙarfin watsawa: ƙarfin watsawa na graphite ya fi ƙarfin ma'adinan da ba na ƙarfe ba sau ɗari. Ƙarfin watsawa na ƙarfe, ƙarfe, gubar da sauran kayan ƙarfe. Ƙarfin watsawa na zafi yana raguwa tare da ƙaruwar zafin jiki, ko da a yanayin zafi mai yawa, graphite ya zama mai rufi;
3. man shafawa: aikin man shafawa na graphite ya dogara da girman flake na graphite, flake, ma'aunin gogayya ya ƙanƙanta, aikin man shafawa ya fi kyau;
4. Daidaiton sinadarai: graphite a zafin jiki na ɗaki yana da kyakkyawan daidaiton sinadarai, juriyar acid, juriyar alkali da juriyar lalata sinadarai;
5. plasticity: ƙarfin graphite yana da kyau, ana iya niƙa shi cikin takarda mai siriri sosai;
6. Juriyar girgizar zafi: graphite a zafin ɗaki idan aka yi amfani da shi zai iya jure wa canje-canje masu tsanani a zafin jiki ba tare da lalacewa ba, canjin zafin jiki, ƙarar graphite ba ta canzawa sosai, ba zai fashe ba.
1. nazarin abubuwan da aka haɗa: carbon mai ƙarfi, danshi, ƙazanta, da sauransu;
2. Gwajin aikin jiki: tauri, toka, danko, fineness, girman barbashi, volatilization, takamaiman nauyi, takamaiman yankin saman, wurin narkewa, da sauransu.
3. gwajin halayen injiniya: ƙarfin tensile, karyewa, gwajin lanƙwasawa, gwajin tensile;
4. Gwajin aikin sinadarai: juriyar ruwa, juriyar juriya, juriyar acid da alkali, juriyar lalata, juriyar yanayi, juriyar zafi, da sauransu
5. Sauran abubuwan gwaji: wutar lantarki, wutar lantarki, man shafawa, daidaiton sinadarai, juriya ga girgizar zafi
