Abstract
We report about the modelling of spark plasma sintering of a line of thermoelectric materials. A significant difference of sintering temperature ΔTs from 15 K to 110 K was found in the samples studied. The Peltier effect on the graphite-thermoelectric interfaces results in such temperature difference. The rise of sintering temperature leads to the ΔTs increase. ΔTs in the vertical direction is 2–3 times higher than in the radial one. Electric insulation modelled in the horizontal graphite–thermoelectric interfaces reduced ΔTs in all the types of numerically studied samples by 59–92%.
