摘要：

Magnesium doped (Zr0.8Sn0.2)TiO4 material has been prepared by solid state reaction and characterized. The samples were sintered in the temperature range of 1270 divided by 1315 degrees C for 2 hours. The effect of sintering temperature on structural and dielectric properties was investigated. The 0.2 wt.% MgO addition improves the sintering process and well sintered samples with a high value of bulk density were achieved. The material exhibits a dielectric constant epsilon(r) similar to 36.6 and high values of the Qxf product, greater than 61000 at microwave frequencies. The dielectric properties make the magnesium doped (Zr0.8Sn0.2)TiO4 material very attractive for such microwave applications as dielectric resonators, filters, dielectric antennas, substrates for hybrid microwave integrated circuits, etc.
