Abstract

The effective reaction depth during the pyrolysis of ceramic injection-moulded bodies in oxidizing atmospheres was deduced from isothermal thermogravimetry. The kinetic data were analysed (i) for the case of chemical reaction control, (ii) for mass transport control and (iii) for combined chemical and mass transport control. The shrinking core reaction modulus indicates that reaction rate was mainly controlled by the diffusion of oxygen into the surface region and degradation products out. The results are used to discuss the relative merits of oxidative and thermal degradation of organic vehicle for ceramic processing. © 1991 Chapman & Hall.
