Summary

A novel ZnO-based composite material is fabricated by oxidation of Zn alloy melts, in which outward growth of the reaction products and rapid reaction kinetics are observed. The resultant ceramic material consists of three-dimensional interconnected ZnO and residual metallic phases. The additions of Na and Bi to the Zn melts are found to be essential to increase the matrix growth rate to a practical level. Reaction rates can be optimized at temperatures ranging from 450 to 550°C. Alloy composition is also observed to have a profound effect on the resulting microstructure and kinetics.
