    A detailed insight into the preparation of nanocrystalline TiO2 powders in supercritical carbon dioxide

    This work reports detailed investigations for the preparation of nanostructured titania powders by a solvent-free sol–gel-derived process, operated in supercritical CO2 (SC-CO2) at high pressures (10–30 MPa) and ...

    Corrosion of 9Cr Steel in CO2 at Intermediate Temperature II: Mechanism of Carburization

    In parallel to the formation of a duplex oxide scale, 9Cr–1Mo steel carburizes strongly under CO2 at 550 °C and this carburization accelerates with time. It is observed that an increase of the total CO2 pressure ...

    Corrosion of 9Cr Steel in CO2 at Intermediate Temperature I: Mechanism of Void-Induced Duplex Oxide Formation

    Under CO2 exposure at an intermediate temperature, typically 550 °C, 9Cr–1Mo steel forms a duplex oxide scale made of an outer magnetite layer and an almost-as-thick inner Fe–Cr rich spinel oxide layer. It is pro...
