A model of the thermal dissocition process has been developed for the numerical simulation of ceramic powder processing in a d.c. plasma reactor.The temperature histories of zircon grains were calculated based on this model.Comparisons were carried out to determine the effects of plasma gas (N2 and Ar),free stream temperature (6000-15000)K and Reynolds number (0.0-1.0) as well as particle diameter(20-200μm)on the zircon dissociation process.The influences of proper Nusselt numer correlation and variable transport properties were discussed in detail.
