Study on appropriate and modified conditions for flash sintering process by simulation modeling

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