This volume contains papers presented during the sixth symposium on Better Ceramics Through Chemistry at the 1994 MRS Spring Meeting, held in San Francisco, April 4--8, 1994. The technical program began with sessions on Precursor Chemistry and Novel Synthesis Routes, where the theme was the control of the microstructure and composition of ceramics by the subtle manipulation of the chemistry during sol-gel processing. Several of the talks reflected a growing interest in hybrid organic-inorganic materials and composites, which provided the topic for the third session and remained a dominant theme throughout the symposium. The program continued with sessions on the Design and Processing of Advanced Ceramics, which included a discussion of the steps than can be taken to improve the quality of thin films prepared by sol-gel processing. Later sessions focused on Sol-Gel Optics and Electronics, such as the formation of encapsulated sensors and the reactions of trapped molecules in porous xerogels. A similar theme was taken up in a later session on Porous Materials, where the emphasis was on novel chemical approaches that are yielding a wide range of new materials, both crystalline and glassy, in which the nanoporosity can be controlled and manipulated. These materials include the newmore » generation of mesoporous-molecular sieves, with pore sizes of up to 100 {angstrom}, which were first synthesized by scientists at Mobil using self-assembling surfactant ``templates``.
