Cementiet is een van de stabiele fasen van staal en bestaat uit chemische verbindingen van drie ijzeratomen en een koolstofatoom, oftewel ijzercarbide (Fe3C). Het ontstaat bij een ijzer-koolstofmengsel dat voor 93,33% uit ijzer en 6,67% uit koolstof bestaat, er wordt dan 100% cementiet gevormd (punt c in de tabel). Cementiet is een hard materiaal, maar het is ook erg bros. Dat wil zeggen dat het nauwelijks te v… Tīmeklis2024. gada 29. aug. · 因此，该Fe3C纳米片@介孔碳复合材料用作锂硫电池的正极硫载体材料时，介孔碳构成了用于分散硫物种的导电网络，而Fe3C纳米片在电子传输，多硫化锂的吸附和催化转化过程中都起着重要的作用，使得锂硫电池面临的几个关键性的难题同时得到了解决。
