Preparation of Copper Particles Coated with Amorphous Titania

Abstract:

Article Preview

Amorphous titania coatings on copper particles were prepared by using tetrabutyl titanate to improve the anticorrosion property. The coated particles were characterized by SEM, EPMA and XRD. Experimental results showed that the resistance to oxidation of the coated copper particles depended on the stability and content of the sol. The proper pH value for the sol was about 4, and the ratio of tetrabutyl titanate and water was 1 to 2. The transmissivity of the etching solution of coated copper particles in 5% of H2SO4 was more than 80%, showing that the TiO2 coatings on copper particles exhibit an excellent corrosion resistance.
