Two or more substances are flowed from different inflow passages, and collided against each other at a flow rate of 4 m/sec or higher to cause a uniform reaction with each other for a short time. This method is advantageous for producing a dispersion liquid containing very fine particles the size of submicrons.

[ What is claimed is:] [1.]1. A method of producing a substance of fine particles comprising:introducing first and second inorganic reactants each dissolved in a solvent into respective first and second longitudinally extending colinear path each having path-defining boundaries and each having a substantially equal and constant traverse cross sectional area along the longitudinal thereof;flowing said first and second reactants substantially colinearly along said first and second colinear path respectively toward a collision enclosure having an enclosure-defining boundary which is co-extensive and colinear with said path-defining boundaries such that the traverse cross sectional area of said enclosure defining boundary is substantially equal to said traverse cross sectional area of said path-defining boundaries;ejecting said first and said reactants into said reactants into said collision enclosure;colliding said first and second reactants head on within said collision enclosure;effecting a substantially instantaneously chemical reaction between said first and second reactants in said collision enclosure as a result of said head-on collision;producing a substance of fine particles in said collision enclosure as a result of said reaction in said collision enclosure;substantially immediately after producing said collision substance conducting said substance from said collision enclosure into a longitudinally extending outlet path having a path-defining boundary in which the outlet path extends laterally of said first and second colinear paths; andeffecting the aforesaid steps continually and non-cyclically.
