Abstract:
1. A process for producing inorganic spheres, comprising: injecting an aqueous liquid comprising an inorganic compound into a laminar flow of an organic liquid which runs at a flow rate of from 0.001 to 2 m/s and at a Reynolds number of at most 2,100 in a flow path through a porous membrane to form a W/O type emulsion; and solidifying the aqueous liquid comprising an inorganic compound in the W/O type emulsion; wherein: the porous membrane has a pore size of from 0.01 to 20 μm; the porous membrane has a porosity of from 10 to 90%; the porous membrane comprises a fluororesin; and the porous membrane comprises fibers that are connected three-dimensionally via nodes.
