Using Bi2O3 and MoO3 as raw materials, by adjusting the ratio of molybdenum and bismuth and the pH of the slurry, Bi2MoO6, Bi2Mo2O9 and Bi2Mo3O12 were co-fired in pairs, two materials with opposite signs of τf value were selected to adjust the τf of the composite, and a near zero τf was developed Value of the microwave dielectric material.
