Abstract

Flash sintering is one of the newest techniques for sintering ceramics to near full density. It occurs in an appropriate combination of temperature and electric field. Temperature measurement is one of the most serious challenges in this process. In the present study, we tried to model a flash sintering process of 8YSZ and 3YSZ with finite element method to make an assessment for temperature distribution and also to estimate the critical values of temperature and electric field intensity. Results indicated the correlation between furnace temperature and electric field intensity and also uniformity of current passage through the sample can be observed by simulation modeling.
