This report describes the effect of exposing a dense, high-alumina castable and a low-iron insulating castable to a simulated coal gasification reactor environment for up to 100 hours and at temperatures up to 2,000 deg f. The castables were characterized by chemical analyses, x-ray diffraction, scanning electron microscopy, and strength measurements. Changes in the castables were related to mineralogical and microstructural changes. This research was carried out in support of Bureau of Mines cooperative work with Energy Research and Development Administration to develop improved refractory liners for coal gasification.
