水热合成的AgPbmSbTe2+m(m=10-18)纳米粉末在Ar气氛中450-480℃无压烧结5h。样品具有较大的正Seebeck系数，但电导率较低，AgPb18SbTe20样品具有较高的功率因数。热压AgPb10SbTe12样品具有纳米级的致密性，且具有不均匀的Seebeck系数。无压烧结和放电等离子烧结的AgPb18SbTe20样品具有明显不同的热电性能。
Hydrothermally synthesized AgPbmSbTe2+m(m=10–18) nanopowders were pressure-less sintered at 450–480°C for 5h in Ar. The samples show large positive Seebeck coefficient but low electrical conductivity and the AgPb18SbTe20sample shows higher power factors. The hot pressed AgPb10SbTe12sample was highly densified with grain size down to nanoscale, and the sample has inhomogeneous Seebeck coefficient. Obviously different thermoelectric properties have been observed for the AgPb18SbTe20samples compacted with pressure-less sintering and spark plasma sintering.
