PRODUCTION METHOD OF ZINC OXIDE CORE-SHELL PARTICLE, ZINC OXIDE CORE-SHELL PARTICLE PRODUCED BY METHOD THEREOF, AND UV LIGHT-SHIELDING COMPOSITION CONTAINING PARTICLE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a production method of zinc oxide core-shell particles having an excellent UV light-shielding function.;SOLUTION: The production method of the zinc oxide core-shell particle contains: a first step of obtaining a first blend by blending a material containing calcium with a first zinc-ammonia complex salt solution; a second step of obtaining a first intermediate product by heating the first blend and removing ammonia; a third step of obtaining a second blend by blending the first intermediate product with a second zinc ammonia complex salt solution; a fourth step of obtaining a second intermediate product by heating the second blend and removing ammonia, followed by drying; and a fifth step of obtaining a zinc oxide core-shell particle by firing the second intermediate product.;SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
