Properties of Refractories after Exposure to High Pressure Gases I
Survey of commercial products
The chemical resistance of the bond phases in eleven commercial and three experimental cement-bonded castables and phosphate-bonded ramming mixes to an atmosphere of CO, CO2, H2O, CH4, H2, and H2S, at 6.9 MPa (1000 psia) for 30 days at 231 and 538 °C was evaluated from physical and mechanical property changes, X-ray diffraction, and DTA/TGA. Cement-bonded castables exposed to the saturated atmosphere showed a significant increase in flexural strength and reduction in porosity which corresponded to the large amounts of boehmite, AIO(OH), formed during exposure. The dissolution of CaO from the cement-bond phases appeared to affect the properties only slightly at these temperatures and pressure. The AIPO4 bond phase was sensitive to saturated atmospheres only.
