Abstract

We present a transient model for the Modified Lely Method for the sublimation growth of SiC single crystals which consists of all conservation laws including reaction-diffusion equations. The model is based on a mixture theory for the gas phase. First numerical results illustrate the influence of the geometrical set-up inside the reactor on the evolution of the temperature distribution.
