场辅助烧结技术（FAST）和放电等离子烧结（SPS）设备基于相同的技术原理，但设计不同。电流直接流过石墨压制工具，石墨压制工具在两台机器中充当加热元件。主要区别在于压制工具的几何形状和材料、电流脉冲和温度测量的位置。在相同的条件下（相同的加热计划、施加的负载和压制工具以及相似的脉冲模式）对两种类型的设置进行了测试。测试了三种不同的氧化物材料：氧化铝、8 mol% 氧化钇稳定氧化锆 (8YSZ) 和氧化锌。
Field-assisted sintering technique (FAST) and spark plasma sintering (SPS) apparatuses are based on the same technical principles, but differ in design. A current flows directly through the graphite pressing tool, which acts as heating element in both machines. The main differences are the pressing tool geometry and material, current pulsing and the position of the temperature measurements. Tests under identical conditions (same heating schedule, applied load, and pressing tool, as well as similar pulse patterns) were conducted on both types of set-ups. Three different oxide materials were tested: alumina, 8 mol% yttria-stabilized zirconia (8YSZ) and zinc oxide.
