Abstract
In the present study, a series of pure and cobalt-doped zinc oxide nanoparticle samples with different concentrations (15, 25, 35, and 45%) of cobalt were successfully synthesized using sol–gel auto-combustion method followed by annealing at 800°C. The crystal structure was characterized using an X-ray diffractometer, revealing that all synthesized samples had hexagonal wurtzite structure. The lattice constants (a and c), crystallite sizes (D), unit cell volume (V), and microstrain (ε) were reported. The Williamson–Hall plot and size–strain plot were also employed to understand the structural and mechanical attributes of the synthesized samples.
期刊介绍：
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
