Title: High temperature alkali corrosion of dense SiC and Si{sub 3}N{sub 4} coated with CMZP and Mg-doped Al{sub 2}TiO{sub 5} in coal gas. Quarterly progress report No. 1, June 3--August 31, 1994

Technical Report ·
OSTI ID:10191383

High temperature alkali corrosion has caused premature failure of SiC and Si{sub 3}N{sub 4} components used in advanced high temperature coal combustion systems. Objective of this research is to develop and characterize CMZP and Mg-doped Al{sub 2}TiO{sub 5} coatings on dense SiC and Si{sub 3}N{sub 4} heat exchanger materials and strive to expand the existing knowledge of the mechanism of coal combustion corrosion of SiC and Si{sub 3}N{sub 4} in the temperature range 1000 to 1400{degrees}C.
