Graphite ne allotrope na carbon, wani tsaka-tsakin crystal tsakanin atomic lu'ulu'u, karfe lu'ulu'u da kwayoyin lu'ulu'u.Generally launin toka baki, taushi texture, m feeling.Ingantacciyar zafi a cikin iska ko oxygen da konewa da kuma samar da carbon dioxide.Karfafa oxidizing jamiái za oxidize shi a cikin. Organic acid.Used as antiwear wakili da lubricating abu, yin crucible, electrode, bushe baturi, fensir gubar.The ikon yinsa, graphite ganewa: halitta graphite, m crystalline graphite, flake graphite, cryptocrystalline graphite, graphite foda, graphite takarda, kumbura graphite, graphite emulsion, fadada graphite, lãka graphite da conductive graphite foda, da dai sauransu.
1. high zafin jiki juriya: da narkewa batu na graphite ne 3850 ± 50 ℃, ko da bayan matsananci-high zazzabi baka kona, da nauyi asara ne sosai kananan, thermal fadada coefficient ne sosai small.The ƙarfi na graphite yana ƙaruwa tare da karuwa da yawan zafin jiki. . A 2000 ℃, ƙarfin graphite ya ninka.
2. conductive, thermal watsin: da conductivity na graphite ne sau ɗari mafi girma fiye da general non-metallic ore.The thermal watsin karfe, baƙin ƙarfe, gubar da sauran karfe kayan.Thermal watsin da karuwa da zafin jiki, ko da a sosai. high zafin jiki, graphite cikin rufi;
3. lubricity: aikin lubrication na graphite ya dogara da girman flake graphite, flake, gogayya coefficient ya fi karami, aikin lubrication ya fi kyau;
4. sinadaran kwanciyar hankali: graphite a dakin zafin jiki yana da kyau sinadaran kwanciyar hankali, acid juriya, alkali juriya da kwayoyin sauran ƙarfi lalata juriya;
5. filastik: ƙarfin graphite yana da kyau, ana iya murƙushe shi cikin takarda mai bakin ciki sosai;
6. thermal shock juriya: graphite a dakin da zafin jiki lokacin da aka yi amfani da shi zai iya jure wa m canje-canje a cikin zafin jiki ba tare da lalacewa, zazzabi maye gurbi, ƙarar graphite canza kadan, ba zai fashe.
1. nazarin abun da ke ciki: ƙayyadaddun carbon, danshi, ƙazanta, da dai sauransu;
2. Gwajin aikin jiki: taurin, ash, danko, fineness, girman barbashi, haɓakawa, ƙayyadaddun nauyi, takamaiman yanki, wurin narkewa, da dai sauransu.
3. Gwajin kaddarorin inji: Ƙarfin ƙarfi, ɓarna, gwajin lanƙwasawa, gwajin gwaji;
4. gwajin aikin sinadarai: juriya na ruwa, karko, juriya acid da alkali, juriya na lalata, juriya yanayi, juriya mai zafi, da sauransu.
5. Sauran abubuwan gwaji: haɓakar lantarki, haɓakar thermal, lubrication, kwanciyar hankali na sinadarai, juriya na girgiza thermal
