Abstract
Cobalt is an important transition metal that plays a critical role in the growing battery industry, and in hard metal applications and super alloys. Cobalt powder can be produced via solid-state hydrogen reduction of different cobalt compounds from which cobalt oxides have been widely studied since 1960s. Hydrogen is an efficient and environmentally friendly reductant and its utilization in metal refining is being increasingly studied. This paper presents an overview of important findings regarding hydrogen reduction kinetics of cobalt oxides alongside thermal decomposition kinetics of cobalt carbonates and hydroxides. This will assist researchers in the future to choose and modify hydrogen reduction parameters by identifying the factors affecting the overall reduction reaction of different cobalt compounds and characteristics of derived cobalt products.
期刊介绍：
Thermochimica Acta publishes original research contributions covering all aspects of thermoanalytical and calorimetric methods and their application to experimental chemistry, physics, biology and engineering. The journal aims to span the whole range from fundamental research to practical application.
The journal focuses on the research that advances physical and analytical science of thermal phenomena. Therefore, the manuscripts are expected to provide important insights into the thermal phenomena studied or to propose significant improvements of analytical or computational techniques employed in thermal studies. Manuscripts that report the results of routine thermal measurements are not suitable for publication in Thermochimica Acta.
The journal particularly welcomes papers from newly emerging areas as well as from the traditional strength areas:
- New and improved instrumentation and methods
- Thermal properties and behavior of materials
- Kinetics of thermally stimulated processes
