UDC 666.768 Phase composition, microstructure and thermomechanical properties of the refractory concrete on the mechano-chemical phosphate-BINDING

Researches thermomechanical properties of refractory concrete based phosphate binders ZrO2, stabilized with 9-10% Y2O3, and Al2O3 with the introduction of modifying additives, obtained by milling a solid phase in an aqueous solution of H3PO4. These concretes have low (~ 1-1.5%) P2O5 content, high strength and heat resistance, which makes it possible to use it as a lining of high temperature (> 2000 ° C) heat units. Joint milling component binder is characterized by mechanical activation and chemical interaction of the surface of the solid phase and the phosphoric acid-activated reaction modifiers conducive to the interaction of the mixture components. The use of phosphate binders corundum composition as protective coatings for refractory materials, allows to increase resistance to aggressive environments and increases the service life of products. Keywords: phosphate binders, builders, mechanochemical interaction, refractory materials, protective coatings.
