Description

Crystal structure and microwave dielectric properties of new types of wolframite materials represented as LiYW2O8 have been characterized using neutron diffraction analysis. The AWO4(a = Ba, Ca) with additives of borates and lithium tungstates for attaining LTCC compositions for microwave dielectric applications. By manipulating the solid solution composition of the system (1- x)LiYW2O8 - xBaWO4 the τf could be controlled near zero values at about x = 0.5. Optimum microwave dielectric property was Qf 19,740GHz, τf = +14ppm, εr = 11.7 at x = 0.4
