Description
Book SynopsisHIGH ELECTRICAL RESISTANCE CREAMICS Pond and fly ash waste materials generated by thermal power stations pollute the environment; this book demonstrates how the utilization of these materials minimizes environmental pollution and conserves land for cultivation. This book highlights the preparation of ceramics using pond/fly ash. Since the mullite phase formed by heat treatment improves the properties of ceramics, current investigations will perhaps be the first attempt to develop ceramics using pond ash. The properties of components made with these developed ceramics are found to be comparable to those made with porcelain. The extensively reviewed chapters of this book illustrate the current status of research on these materials. At the end of each of the 10 chapters, conclusions are drawn which will benefit researchers working in this area. Subjects discussed include: The fundamentals of thermal power plant wastes;Different production methods of ceramics and various characterization t
