Description
Summary:The advantage and disadvantages of a number of chemical routes for the preparation of high-temperature superconducting powders are discussed. Chemical preparation is considered to be superior to conventional ceramic preparation because: reaction temperatures are lower; phases may be synthesised which cannot be prepared directly by a ceramic route; the powders are more homogenous; and the end product has superior properties. Techniques considered include coprecipitation, sol-gel, freeze-drying and spray pyrolysis. 54 refs.
