A higher ramp of 10 °C/min in the temperature range of 400 °C to 600 °C and lower ramp of 2 °C/min above 600 °C (modulated heating), were found to be effective in realizing monophasic PMN-PT ceramic. Calcination and stabilization temperatures were fixed at 850 °C for 6 h and 1050 °C for 4 h respectively.
The melting point is decreased with 5–10 °C for all composite materials, indicating nanoconfinement effects of the interparticle salt phase. This work therefore provides a new strategy for obtaining shape-stabilized materials useful for high – temperature heat storage.
