Abstract:
A ceramics as microwave medium has a chemical formula: CaO-2MO-xTiO2, where M is chosen from Zn, Cu, Ni and Mg and x=5-10. It is prepared through proportionally dissolving nitrate, butyl titanate and citric acid in deionized water, adding ammonia water to become sol, heating to become gel, calcining to become activated powder, wet grinding, die pressing and sintering at 1000-1100 deg.C.
