Ceramic powder synthesis-current status and future challenges
- Rutgers, The State Univ. of New Jersey, Piscataway, NJ (United States)
The synthesis of ceramic powders has been an area of research and development that continues to garner interest from scientists and engineers. Technological driving forces for this interest include new properties (e.g., 1), new microstructures (e.g., 2), lower processing temperatures (e.g., 3,4) and reproducibility that will reduce rejection rates (e.g., 5). The scientific driving force is development of model microstructures that will shed light on the fundamentals of processes such as dispersion, granulation, forming and densification and develop more precise relationships between microstructure and properties. Our {open_quotes}wish list{close_quotes} of controllable characteristics include particle size, particle size distribution, morphology, of aggregation, phase, bulk chemistry, chemical purity, surface chemistry and loss on ignition (volatile content). Our {open_quotes}wish list{close_quotes} needs of the ceramist to utilize multicomponent compositions (usually with respect to cation) and to be able to tailor it with a wide range of flexibility. For the purposes of this discussion, ceramic powder synthesis includes all processing routes for preparing a particulate inorganic compound where a chemical reaction is required at some point in the process. The focus of this paper is to provide an overview of present powder synthesis technology, briefly assess its overall status and provide a direction for its future.
