采用常规固相反应法制备了添加li2tio3的sio2陶瓷,并对其相演化、化学反应、微观结构和微波介电性能进行了研究。添加li2tio3的sio2陶瓷的微波介电性能与Li2(TiO)(SiO4)中间相的形成和分解密切相关。在1150°C以上烧结的样品均形成了钇铝石相,并首次报道了其微波介电性能(ϵr= 2.58,Q×f= 25,800 GHz,τf= - 17.8 ppm/°C)。在1050°C下烧结的0.945 sio2 - 0.055 li2tio3陶瓷具有良好的微波介电性能:ϵr= 3.21,Q×f= 10,180 GHz, τf ~ 0.17 ppm/°C。
Using a conventional solid-state reaction method SiO2ceramics with addition of Li2TiO3were synthesized and their phase evolution, chemical reactions, microstructure and microwave dielectric properties were studied. The microwave dielectric properties of SiO2ceramics with addition of Li2TiO3strongly depend on the formation and the decomposed of Li2(TiO)(SiO4) intermediate phase. The tridymite phase was formed for all samples sintered above 1150 °C and its microwave dielectric properties were reported for the first time (ϵr= 2.58,Q×f= 25,800 GHz,τf= −17.8 ppm/°C). The promising ceramics of 0.945SiO2–0.055Li2TiO3sintered at 1050 °C were found to possess good microwave dielectric properties:ϵr= 3.21,Q×f= 10,180 GHz andτf∼ 0.17 ppm/°C.
