Process for producing inorganic particulate material in the form of fine balls approximately uniform in size
摘要
<p>An inorganic particulate material comprising fine balls of approximately uniform in size and 0,1 to 50 mu m in mean particle size, prepared by admixing at least two aqueous solutions capable of forming an inorganic precipitate, one solution being admixed with an organic solvent, whereby said aqueous solution of at least one inorganic compound is forced into said organic solvent through a micro porous membrane having microporous of uniform diameter and rendered hydrophobic.</p>
