Amorphous and crystalline powder of PLT phase was synthesized by using the Pechini method. Infrared (FTIR) analysis of the polymeric resin shows intense bands of organic materials from 250 to 1620 cm−1. X-ray diffraction (XRD) and Raman spectra of calcined powder at different temperatures show amorphous phase at 450 ◦C/3 h, semi-crystalline phase at 550 ◦C/3 h and a crystalline phase at 800 ◦C/...
