ABSTRACT:
High purity magnesium oxide fine particles are produced by introducing a flow of a magnesium vapor-containing gas and a flow of an inert gas separately into a mixing region to provide a flow of a mixture gas; by introducing the flow of the mixture gas into an oxidizing region while a flow of a molecular oxygen-containing gas is introduced into the oxidizing region concurrently with the flow of the mixture gas; to provide a flow of a reaction mixture in which the magnesium vapor is oxidized, by introducing the flow of the reaction mixture containing the resultant magnesium oxide fine particles into a collecting region; and, by collecting the magnesium oxide particles from the reaction mixture by, for example, a filter located in the collecting region.
