•Zinc borate glass lowered the sintering temperature of willemite effectively.•A non-reactive sintering mechanism was discussed in detail.•A new dielectric for LTCC was provided
In this work, the effects of 3ZnO-2B2O3 glass on sintering temperature, phase composition, microstructure and dielectric properties of Zn1.8SiO3.8 ceramics were investigated. The x-ray diffraction results showed that there no reaction between the glass and the ceramic during the sintering process. A mechanism of densification and microstructure evolution of the ceramics with glass was provided based on the x-ray, density and scanning electronic microscopy results. The study on the dielectric properties showed strong dependences of glass content and sintering temperature. At last, the compact ceramic with 20 wt% glass content, exhibited a dielectric constant of 6.5 and a low loss of 0.001, after sintering at 920 °C.
