Abstract
Calcium oxide andJor magnesium oxide are introduced in different ways to high purity wustite powders, followed by metallization in mixtures of CO, CO2, and N2 at 750, 900, and 1100 °C. A new technique is developed to study the nucleation and growth of iron where wustite plates are coated with thin films of CaO of MgO prior to metallization. Calcia, in solid solution with wustite, influences the kinetics of metallization and the morphology of iron. It is reasonably confirmed that nucleation and outward growth of iron, to form iron whiskers, occur at sites higher in CaO concentration on the wustite surface. MgO, on the other hand, has almost no noticeable effect on the iron whisker formation.
