Thermal shock damage characterization of refractory composites
MetadataShow full item record
The possibility of using dolomite and bauxite for synthesis of high temperature castable was studied. Behavior of the material in conditions of rapid temperature changes was investigated. Water quench test was applied to determine thermal shock resistance. Level of surface deterioration before and during quenching was monitored by image analysis. Dynamic Young modulus of elasticity was determinated by ultrasonic measurements. The results show that dolomite and bauxite can be effective raw materials for low temperature synthesis of refractory composites. (C) 2007 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
