Abstract:
The objective of this research program is to develop the chemistry and applications of a new biomimetic in situ synthetic system for the fabrication of inorganicorganic composite materials. The research focuses on understanding the mechanisms of the solid-state syntheses which give rise to composites in which the crystals of the inorganic phase are identical in size, morphology, and crystallographic orientation, the determining characteristics of naturally-formed biological composites. Synthesis of a new class of ordered composites, the high pressure lead sulfide phases, was carried out, and evaluation of these new materials optoelectronic properties will be attempted. Synthesis of high-pressure phases of refractory ceramics such as boron nitride, will be attempted. An extension of the biomimetic synthetic process, an analogue of the solution sol-gel synthetic scheme for oxide ceramics, will also be studied in order to optimize a previously unknown process, the production of nonoxide ceramics by a solution sol-gel route.
