Abstract: A low loss dielectric material useful as the raw materials of receiver for satellite communication, sensor for burglar-alarm system, laser detector of speed gun, and card radio is manufactured. The dielectric material for high frequency comprises (Zrx, Sn1-x)TiyO4 as fundamental material, where the total amount of x and y is 100wt.%; ZrO2 (x is morethan 37.6 and less than 47.2wt.%); SnO2 (1-x is more than 14.5 and lessthan 24.8wt.%); TiO2 (y is more than 37.6 and less than 38.3wt.%). The sintering adjuvants being added to the fundamental dielectric materialconsists of B2O3 0.3-2.0wt.%, La2O3 0.3wt.% and NiTa2O7 0.3-2.0wt.%.
