Following the sol-gel processing sequence from beginning to end, this work includes discussions on the chemistry of hydrolysis and condensation of metalorganics and inorganic salts, the growth of polymeric or particulate species in sols, gelation, aging of gels, drying, structure of gels, and sintering. In addition, it compares the properties of gel-derived and conventionally prepared ceramics, examines films in detail, and surveys a wide variety of applications.
