A method of manufacturing a fine, monodisperse powder of binary oxidic compounds of at least one metal selected from the group consisting of the groups Ib, IIa, IIb, IIIa, IIIb, IVa, IVb, Va, Vb, VIa, VIb, VIIa, VIIb, VIII of the periodic table, the lanthanides and the actinides comprising:
- a) forming a graphite intercalation compound of said at least one metal by reacting at least one compound of said at least one metal with a graphite having a particle size.ltoreq.150 .mu.m, and
- b) heating the resultant graphite intercalation compound at a temperature of 500.degree. C.-1000.degree. C. under oxidizing conditions for a time sufficient to convert said graphite intercalation compound into a binary oxidic compounds of said at least one metal.
