摘要: Sol-gel processes are interesting from a scientific point of view as well for new or potential industrial applications. In some rare examples, sols gels can be used end products. Most often however, they must transformed to an appropriate ceramic phase with properties and also densified. detail, sol-gel fabrication process is made according chronology post-gelation treatment which depends on the product. Those products retained in present chapter final materials, coatings, fibers, monoliths, hybrid organic-inorganic materials high specific surface area such filtering membranes catalysts. On other hand, powders glasses usually intermediate applications just mentioned before. They were largely addressed 3 7 not reconsidered chapter.
