Title:
VANADIUM OXIDE AND RARE EARTH DOUBLE-DOPED FERRITE MAGNETIC COMPOSITE FILM SLURRY PREPARATION PROCESS AND COATING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/088057
Kind Code:
A1
Abstract:
Disclosed in the present invention are a vanadium oxide and rare earth double-doped ferrite magnetic composite film slurry preparation process and coating method. According to the method, a vanadium oxide and rare earth double-doped ferrite magnetic composite film slurry is obtained by means of a rare earth oxide sol process, a ferrite sol process, a rare earth ferrite sol-gel process and a vanadium-doped sol-gel slurry process, and the slurry can complete base coating by means of an improved pulling coating process and silk-screen printing coating process. The present invention solves the problems of material inactivation due to the fact that a magnetic film is separated from a base in the use of a magnetic film material, cracks and gaps in the material caused by nonuniform distribution of the magnetic film material, and the like, and improves the performance of the magnetic film material.
