Sic samples coated with CMZP and Mg-AI2TiO5, respectively, were tested in a 100-hour slagging combustion test at the Energy and Environmental Research Center at the University of North Dakota. The results of measurements and analysis indicate that CMZP and Mg-AI2TiO5 coatings improved the high temperature alkali corrosion resistance under coal combustion atmospheres. It is clearly shown that it is important to obtain a homogeneous and crack-free coating and good adhesion of the coating to the
