Abstract

Ceramic composition of Barium tetra titanate (BaTi4O9) is prepared via conventional solid state, mixed oxides route.The XRD revealed a single phase orthorhombic (Amm2)structured BaTi4O9compound calcined at 1250 °C for 2 h in air. Thevalues of the relative permittivity (εr) varied from∼38 to 43 and quality factor (Q ×f) from∼27000 to 39000 GHzat 3 GHz frequency with increasing sintering temperatures ranging from 1500 °C to 1580 °C in air. The microwave dielectric properties of the sintered ceramicsample depend considerably on sintering temperature and their microstructure. BaTi4O9 can be a promising microwave dielectric material for microwave applications..
