Abstract

The thermoelectric properties of potassium interstitial doped Sr0.7Ba0.3KxNb2O6−δ ceramics were investigated in the temperature range from 323 to 1073 K. The thermoelectric power factor is improved enormously due to the potassium interstitial doping combined with a reductive calcination method. The potassium dopants not only act as carrier donors but also modulate the electronic structures. Thus, the electrical conductivity increases remarkably, and the Seebeck coefficient, meanwhile, maintains considerable values at high temperatures. Only the moderate doping content x = 0.10 contributes to reducing the lattice thermal conductivity. Thus, the sample Sr0.7Ba0.3K0.1Nb2O6−δ shows the highest ZT value of 0.23 at 1073 K.
