Heat-Insulating Ceramics which Have a Nanoporous Structure and are Made with the Use of Ash-Bearing Wastes from Power Plants

It is determined that the pore-forming effect exhibited by ash and ash microspheres in compositions with clayey rocks is due not only to certain structural features (the presence of spherical hollow particles) and the makeup of the ash components (the presence of residual fuel in the ash) but also t...

Summary:It is determined that the pore-forming effect exhibited by ash and ash microspheres in compositions with clayey rocks is due not only to certain structural features (the presence of spherical hollow particles) and the makeup of the ash components (the presence of residual fuel in the ash) but also to physico-chemical processes (the synthesis of anorthite and mullite) which take place in clay – ash-and-clay – ash- microsphere systems and prevent shrinkage during sintering.
