Abstract

Abstract CoAl 2 O 4 powder was obtained from a mixture of Co and Al oxalates at a ratio of 1:8 (Co:Al). The material was calcinated at different temperatures, established from TG data, and characterized using FTIR spectroscopy, X-ray diffraction, BET surface area, and thermal analysis. The dyeing characteristics of CoAl 2 O 4 were established by coating ceramic substrates with different concentrations of the powder.
