Abstract
Physicochemical regularities of processes occurring in the “polyorganosiloxane-silicate-metal oxide” system are investigated over a wide range of temperatures. The results of investigations are used to design organosilicate materials, such as heat-resistant functional coatings, high-temperature adhesives, and vacuum-tight sealants, which find wide application in various fields of engineering. Modern materials science of organosilicate composites is a dynamic knowledge system.
