Title of the articleTo the question of studing the mechanism of increasing the durability of a porous ceramic crock at introduction of chemical additives
Abstract.The competitiveness of ceramic wall products in the market of construction materials can be increased by improvement of their heat-shielding properties. It is possible to lower average density and heat conductivity of ceramic wall products by a porization of a crock and increase in hollowness of products. Reducing the average density and heat conductivity of products by introduction of burnable additives their strength characteristics decrease also. Therefore, it is necessary to provide the increase of durability of a crock at introduction of burnable additives in furnace charge. The article considers mechanisms of increase of durability of a ceramic crock by mechanical activation of clay raw materials or introduction of chemical additives. Increasing the strength of the crock can be explained like this. Crystalline phase of the crock is formed by firing ceramic products, which based on medium plastic clay and include galvanic production waste. This crystalline phase contains needles of mullit, which reinforce glass phase by melting of conglamerate faces. If glass phase increases strength of the ceramic crock raises.
Keywords.Ceramics, galvanic production waste, spent-soap lye, crystalline phase, glass phase.
