METHOD FOR PRODUCING SLURRY CONTAINING SPHERICAL INORGANIC PARTICLES
Document Type and Number:
WIPO Patent Application WO/2024/009896
Kind Code:
A1
Abstract:
The present invention provides a method which is for producing, by wet classification, a slurry containing spherical inorganic particles and in which spherical inorganic particles having a narrow particle-size distribution are continuously obtained. This production method comprises passing a crude slurry containing spherical inorganic particles through a separation membrane to produce a slurry, wherein the separation membrane has pores that are approximately even in size, and a flow along the surface of the separation membrane is formed on the primary side of the separation membrane and ultrasonic waves are applied to the separation membrane.
