ABSTRACT OF THE DISCLOSURE A method for improving the density of caustic magnesia and sintered periclase. To improve the density of sintered periclase, acid or acid salt is admixed with magnesium hydroxide, followed by drying, caustic-firing, pressing and high-firing. Preferably, acetic acid is used. Alternatively, the step of caustic-firing may be omitted. To improve the density and compactability of caustic magnesia, acid or acid salt is admixed with magnesium hydroxide, followed by drying and caustic-firing. Preferably, acetic acid is used.
