Binder and polymeric-ceramic material filled with nanosized Al2O3

The production of polymer-ceramic materials with high technological and mechanical properties requires the development of effective binders. The article considers the influence of modifiers on the curing process of polymethylsiloxane resin. It is shown that the introduction of modifiers helps to reduce the viscosity of the resin, and in the presence of a hardener, it makes it possible to obtain a binder with a low viscosity and an acceptable gelation time. Polymer-ceramic material based on the developed binder and nanoscale plasma-chemical Al2O3 powder has high mechanical properties, reduced shrinkage and porosity.
