Review: environmental friendly lead-free piezoelectric materials
TL;DR: In this article, the authors reviewed the recent developments on lead-free piezo materials emphasizing on their preparation, structure-property correlation, etc., and concluded that some lead free compositions show stable piezoelectric responses even though they do not match the overall performance of PZT.

Piezoelectric properties of Li- and Ta-modified (K0.5Na0.5)NbO3 ceramics
TL;DR: Guo et al. as discussed by the authors showed that high densities and piezoelectric properties can be obtained for all compositions by pressureless sintering in air, without cold isostatic pressing, and without any sinterings aid or special powder treatment.

Mass Transport and Sintering in Impure Ionic Solids
TL;DR: In this article, the chemical potentials of the constituents in an impure ionic solid are derived as a function of the pressure and the impurity concentration, and the theory is applied to a sintering model which illustrates a possible effect of impurity additions on sinting rates.
