Abstract

The effects of TiO2 addition on the densification, microstructure and microwave dielectric properties of pseudo-wollastonite ceramics (α-CaSiO3) have been investigated. The X-ray diffraction (XRD) patterns results indicate that samples exhibit a two-phase system, which has a wollastonite-structured α-CaSiO3 primary phase associated with a CaTiSiO5 minor phase. However, the TiO2 addition undermines the microwave dielectric properties because of the poor quality factor of the secondary phase of CaTiSiO5, which can inhibit the growth of α-CaSiO3 grains by surrounding their boundaries. The α-CaSiO3 ceramics containing 2 wt% of TiO2 sintered at 1,300 °C showed excellent microwave dielectric properties: an ε r value of 7.86, a quality factor Q × f value of 16,491 GHz, and a τ f value of 0.76 ppm/ °C.
