Кots L. Вioresistant non-biocidal facade ceramic materials

Object of research: the formation process of bioresistant environmentally friendly facade ceramics; biological destruction of facade materials, which are exposed to aggressive environmental and biological factors. Objective: developing of technology of the facade ceramic products resistance to biological affection and to creating criteria and methodology for assessing the biological stability of the building materials. Methods: laser-scanning microscopy, pulse-amplitude fluorometry, X-ray analysis, differential-thermal analysis, dilatometer analysis petrographic analysis, electron-microscopic analysis, chemical analysis. Theoretical and practical results: On the base of Na2O-K2O-CaO-MgO-Al2O3-SiO2 system the technology of bioresistant non-biocide facade tile with the complex of highly exploited properties were developed; the criteria of the predictive evaluation of facade products biological stability were grounded and the method for rapid-testing their resistance to biological affection was created. Novelty: theoretically substantiated and experimentally demonstrate the possibility of non-biocide ceramic material with high bioresistance at the expense of the directional control of the structure and surface properties; the regularities of non-biocide facade ceramics formation under conditions of forced heat treatment, which are as rapid sintering with the participation of low-viscosity melt, capable to crystallization of chemically stable mullite and diopside phases, were set. The degree of approbation: in the CJSC "ZeusCeramic" (Slovjansk) successfully conducted industrial tests. Sphere use: production of facade building materials.
