摘要：

ZnTiO3 powders and borosilicate glass were made by sol-gel method, and then mixed for co-firing at low temperatures. The results show that the borosilicate glass was liquefied to improve the density of the ceramic during sintering. However, Zn4O(BO2)(6) and TiO2 were formed if too much borosilicate glass was added (over 10 wt.%). The microwave dielectric properties of the ZnTiO3 co-fired with borosilicate glass were also improved dramatically. With 5 wt.% borosilicate glass addition, ZnTiO3 ceramics can be sintered at 850 degrees C and shows excellent microwave properties: 22.2 for dielectric constant, and 52,460 for Q x f value at a frequency of 6 GHz.
