通过在300°C的N2气氛中保持正常的浮氏体（δ值为0.94）10分钟来制备活性浮氏体（FeδO，δ值为0.98）。该反应由（4δ2-3）Feδ 1 O →（4δ1-3）Feδ 2 O+（δ2-δ1）Fe 3 O 4给出，其中δ1= 0.94且δ2= 0.98。该方程表明，正常的浮氏体经历共析分解为活性浮氏体和化学计量的磁铁矿（Fe 3 O 4）。CO2（1.013 × 105 Pa）在300°C的低温下几乎完全（100%）被活性浮氏体分解为碳（零价），这与活性浮氏体转变为化学计量的磁铁矿有关。反应池的内部压力最终变成真空。
Active wustite (FeδO, with a δ value of 0.98) was prepared by keeping normal wustite (δ value of 0.94) in a N2 atmosphere at 300°C for 10 min. This reaction is given by (4δ2–3)Feδ1O→(4δ1–3)Feδ2O + (δ2–δ1)Fe3O4 where δ1= 0.94 and δ2= 0.98. The equation indicates that the normal wustite undergoes eutectoid decomposition into active wustite and stoichiometric magnetite (Fe3O4). Carbon dioxide (1.013 × 105 Pa) was almost completely (100%) decomposed into carbon (zero valence) by the active wustite at the low temperature of 300°C, which was associated with the transformation of the active wustite into the stoichiometric magnetite. The internal pressure of the reaction cell eventually became a vacuum.
