      abstract     = {The influence of advanced thermal insulation on energy
                      consumption and temperature distribution during electric
                      field assisted sintering of conductive stainless steel
                      powder and non-conductive zirconia powder was investigated.
                      Four types of tool setup were considered: i) without
                      insulation, ii) with die wall insulation, iii) with
                      additional insulation of die faces and iv) with spacers
                      manufactured from carbon fiber reinforced carbon composite
                      (CFRC). The influence of thermal insulation on energy
                      consumption was experimentally studied for samples with
                      diameter of 17 mm. The temperature distribution in samples
                      with diameters of 17 mm, 50 mm and 150 mm was modeled
                      using the Finite Element Method. The power consumed during
                      dwell was almost half the value when die wall insulation was
                      used. The additional insulation of die faces and the
                      application of CFRC spacers provide a threefold decrease in
                      power during sintering of steel powder and a fivefold
                      reduction during sintering of zirconia powder. The advanced
                      thermal insulation significantly homogenizes the temperature
                      distribution within samples of small and medium size. The
                      advanced thermal insulation provides a strong decrease in
                      the temperature gradient inside large conductive sample with
                      a diameter of 150 mm. However, insulation apparently
                      cannot ensure acceptable temperature homogeneity within
                      non-conductive parts of such diameter. The reason for this
                      is the specific current path and related heat concentration
                      near the sample edge.},
