Study on Low-Temperature Sintering of Microwave Dielectric Ceramics by Sol-Coating Method

Abstract:

Article Preview

Microwave dielectric ceramics with low sintering temperature were obtained by sol-coating method. The effect of glass additives on the sintering temperature and microwave dielectric properties of BaO–Nd2O3–TiO2 ceramics were investigated. The ceramics added with NBS glass have much higher quality factor Qf= 4658.9 GHz. The ceramics added with BBS glass have the highest dielectric constantεr=71.4 and lest temperature coefficient of resonant frequency τf =29.15×10-6/ °C. The ceramics added BBS glass are as follows:εr=58.58, Qf= 2986GHz, τf =29.15×10-6/ °C sintered at 1060°C where the ceramics can be co-fired with copper electrode.
