Innovative Technology for Fabrication of Ceramics: EDS Rapid Solidification Process Application to Specialized Materials

摘要

This report presents results of innovative research on a novel rapid solidification technology method to produce fine ceramic powders of many compositions with unique properties. The process uses salt solutions and includes two steps, the first to evaporate the liquid and the second to very rapidly decompose the salt to a very fine powder. The process has been demonstrated in terms of the following material applications: aluminates, ferrites, phosphors, ionic conductors, and cements. This new technique of producing ceramic powders offers a number of potential advantages over existing methods such as ability to produce complex compositions, lower energy requirements, and improved properties.
