Properties of Refractories after Exposure to High Pressure Gases V
Effect of repeated boehmite formation and decomposition
The physical properties and flexural strength of dense alumina and lightweight insulating castables were investigated after exposure to a mixture of CO, CO2, CH4, H2, H2O (steam), and 1 vol pct H2S at 6.9 M Pa. The temperature was cycled between 240 °C to form boehmite and 538 °C to decompose boehmite a total of five times. A high purity alumina castable became weaker after boehmite decomposition. The flexural strength of dense alumina castables containing silica either remained the same or increased after boehmite decomposition. The properties of insulating castables were essentially unaffected by cyclic exposure.
