Graphite shine allotrope na carbon, crystal mai jujjuyawa tsakanin lu'ulu'u na atomic, lu'ulu'u na ƙarfe da lu'ulu'u. Gabaɗaya launin toka mai launin toka, laushi mai taushi, ji mai daɗi. Ingantaccen zafi a cikin iska ko iskar oxygen wanda ke ƙonewa da samar da iskar carbon dioxide. Organic acid.Ya yi amfani da shi azaman wakilin riga -kafi da kayan shafawa, yin ƙwanƙwasawa, lantarki, bushewar baturi, gubar fensir. Girman gano hoto: graphite na halitta, m crystalline graphite, flake graphite, cryptocrystalline graphite, graphite powder, graphite paper, fadada graphite, Graphite emulsion, fadada graphite, yumbu graphite da conductive graphite foda, da dai sauransu.
1. babban zafin juriya: wurin narkar da graphite shine 3850 ± 50 ℃, koda bayan matsanancin zafin arc yana ƙonawa, asarar nauyi ƙanƙanta ce, maɗaurin faɗaɗawar zafi yana da ƙanƙanta Ƙarfin graphite yana ƙaruwa tare da karuwar zafin jiki . A 2000 ℃, ƙarfin graphite ya ninka.
2. conductive, thermal conductivity: conductivity na graphite ne sau ɗari mafi girma daga janar ba ƙarfe. The thermal watsin na karfe, baƙin ƙarfe, gubar da sauran karfe kayan.Thermal watsin raguwa tare da karuwa da zazzabi, ko da a sosai high zazzabi, graphite cikin rufi;
3. lubricity: aikin lubrication na graphite ya dogara da girman graphite flake, flake, gogayya coefficient ne karami, aikin lubrication ya fi kyau;
4. kwanciyar hankali na sinadarai: graphite a zafin jiki yana da kyakkyawan kwanciyar hankali na sinadarai, juriya na acid, juriya na alkali da juriya na lalata lalata;
