| Abstract Scope |
In the pseudobinary system In3Ti2AO10 – In6Ti6BO22 (A: trivalent cation; B: divalent cation) both A and B have coordination number CN = 5 (trigonobipyramidal sites). In this work this system was studied by means of the high entropy ceramics approach. The compound In12Ti10AlGaMg0.5Zn0.5O42 was obtained by the solid state reaction method, and its structural stability in the 1200-1500°C range of temperatures was evaluated. XRD and SEM facilities were used to characterize the present phases. EDS with elemental mapping analysis was used to demonstrate the configurational high-entropy dimension. Single phase samples of 120 mg were pelletized and sintered in high alumina crucibles, and silver painted as capacitors-like to make dielectric meassurements from room temperature to 550 °C in the frequency range of 1–50 kHz, and their results are compared with closely related compounds. |
