Abstract

The invention relates to a method for synthesising a powder, said method comprising the following successive steps: A) the preparation of a mother liquor comprising i. an oxide base constituent or a precursor of said base constituent and an additional constituent of formula MC, the additional constituent consisting of an agent M selected from the group of oxoanions, anions of the elements of column 17 of the periodic table of elements, hydroxide OH-, and the mixtures thereof, and a complement C which is inorganic when the agent is hydroxide OH-; or ii. an oxide base constituent or a precursor of the base constituent comprising an agent M selected from the group of oxoanions, anions of the elements of column 17 of the periodic table of elements, and the mixtures thereof; B) the hydrothermal preparation of a sol, from said mother liquor, containing coarse particles of a maximum size higher than 10 nm and lower than 250 nm, or even lower than 100 nm; and C) the sol is washed in such a way as to obtain, following a drying stage, a powder comprising more than 99.3 % of the base constituent, in weight per cent in relation to the dry material.
