    Finite-difference model for the reaction sintering of oxide ceramics by direct oxidation of intermetallic powder compacts

    A kinetic model for the reaction sintering of oxide ceramics in the system Al2O3–SiO2–ZrO2 using mixtures of intermetallic compounds is presented. A 2D finite-difference model is developed to describe the exother...

    Kinetic model of the oxidation of ZrSi2 powders

    The oxidation kinetics of Zr-disilicide (ZrSi2) powders up to temperatures of 1550°C were studied in flowing air using non-isothermal and isothermal thermogravimetric (TG) analysis. During the oxidation process t...
