Abstract:
A method of preparing core-shell zinc oxide particles, includes: mixing a calcium-containing material with a first zinc ammonia complex salt solution; heating the thus obtained first mixture to remove ammonia, thereby obtaining a first intermediate product; mixing the first intermediate product with a second zinc ammonia complex salt solution to obtain a second mixture; heating the second mixture to remove ammonia, followed by conducting a drying process to obtain a second intermediate product; and calcining the second intermediate product to obtain the core-shell zinc oxide particles. A core-shell zinc oxide particle is prepared by the aforementioned method, and a composition for shielding ultraviolet light includes the core-shell zinc oxide particles.

Claim (Index 2):
The method as claimed in  claim 1 , wherein the step of calcining the second intermediate product is conducted at a temperature ranging from 340\u00b0 C. to 360\u00b0 C.
