(510aq) Fabrication And Durability Of Ceramic Microchannel Devices For Sulfuric Acid Decomposition

The thermochemical decomposition of sulfuric acid can be used to produce hydrogen from water and heat. Various processes in the cycle generate corrosive environments that can limit the lifetime of reactor components. Ceramic materials offer high temperature structural properties and corrosion resistance. In order to use these materials in practical components, an understanding of the effect of these environments on the properties, especially strength and reliability, are required. The results of corrosion testing, strength testing, and microscopy after exposure of various ceramic materials to conditions relevant to the thermochemical decomposition of sulfuric acid will be discussed.
