Low-temperature co-fired microwave dielectric ceramic material, and preparation method and application thereof

摘要

A low-temperature co-fired microwave dielectric ceramic material includes: (a) 85 wt % to 99 wt % ceramic material comprising Mg₂SiO₄, Ca₂SiO₄, CaTiO₃, and CaZrO₃, wherein a weight ratio of Mg₂SiO₄ relative to Ca₂SiO₄ is of (1-x): x, a weight ratio of CaTiO₃ relative to CaZrO₃ is of y:z, and a weight ratio of entities of Mg₂SiO₄ and Ca₂SiO₄ relative to CaTiO₃ is of (1-y-z):y, 0.2≤x≤0.7, 0.05≤y≤0.2, 0.05≤z≤0.4; and (b) 1 wt % to 15 wt % glass material composed of Li₂O, BaO, SrO, CaO, B₂O₃, and SiO₂.
