Title:
MICROSPHERE CONTAINING POLYDISPERSED POLYMER NANOSPHERE AND POROUS METAL OXIDE MICROSPHERE
Document Type and Number:
Japanese Patent JP2023015318
Kind Code:
A
Abstract:
To provide porous metal oxide microspheres which exhibit visible color of high quality in bulk.SOLUTION: Porous microspheres containing metal oxides have a continuous solid structure, wherein each porous microsphere has two or more pore populations having different average pore diameters, distributed over the whole volume of the porous microsphere. Preferably, the porous microsphere has an average diameter of 4.5 μm to 9.9 μm; average porosity of 0.45 to 0.65; and an average pore size of 220 nm to 300 nm.SELECTED DRAWING: None
