High temperature alkali corrosion kinetics of low expansion ceramics
The gaseous alkali corrosion kinetics of silicon carbide, silicon nitride, alumina, mullite, cordierite, transformation toughened zirconia, and aluminum titanate were systematically investigated from 950°C to 1100°C in dry air containing 1.0 +/- 0.1 vol% alkali. The linear reaction rates observed …

Long-term thermal/chemical degradation of ceramic candle filter materials
… harsh environments to determine the effects of alkali and steam on their long-term durability. Ceramic candle filters are composed of relatively coarse aggregates fixed by a ceramic bond. The filters studied include a clay-bonded, granular aluminosilicate candle and three types of clay-bonded, …

Corrosion resistance of NZP and aluminum titanate
… the mechanical and thermal properties and corrosion resistance were evaluated. NZP (Ba<sub>1.25</sub>Zr₄P<sub>5.5</sub>Si<sub>.0.5</sub>0₂₄ and Ca<sub>0.5</sub> Sr<sub>O.5</sub>Zr₄P₆0₂₄) and aluminum titanate (AT) were exposed to a simulated diesel engine environment. The effects of thermal …

CMZP and Mg-doped Al2TiO5 Thin film Coatings for High Temperature Corrosion Protection of Si3N4 Heat Exchangers
… severely reduced by oxidation. To increase its corrosion resistance, the formation of a protective oxidation barrier layer was promoted by the deposition of oxide thin films. Homogeneous and crack-free oxide coatings of calcium magnesium zirconium phosphate (CMZP) and magnesium doped aluminum …
