Tio2 Addition

The LiZnPO4 ceramic has been prepared by the conventional solid state ceramic route. The ceramic sintered at 825 °C has an εr of 4.9, Qu×f of 65400 GHz, and τf of −80 ppm/°C. The LiZnPO4 ceramic shows low coefficient of thermal expansion (CTE) of 5.3 ppm/°C. The slightly large negative τf of LiZnPO4 has been tuned nearly to zero with TiO2 addition. LiZnPO4-TiO2 composite containing 0.15 volume fraction TiO2 sintered at 925 °C shows good microwave dielectric properties: εr = 7.8, Qu×f = 39800 GHz and τf = −6.8 ppm/°C. LiZnPO4−0.15 Vf TiO2 composite shows a CTE of 6.9 ppm/°C.
