This paper presents a systematic study about the importance of employing properties evaluated as a function of temperature to input a computer simulation program using the finite element method (FEM), in order to access the temperature and normal stress profiles in a refractory ceramic. The properties evaluated as a function of temperature were thermal conductivity (k), specific heat (c), coefficient of linear thermal expansion (alphaL), and elastic modulus (E). A 2u experimental design and the analysis of variance (ANOVA) allowed to conclude that the thermal conductivity and the specific heat are important to obtain a more precise temperature profile, while the linear thermal expansion coefficient and the elastic modulus are important to evaluate the stress profile.
