High-performance dielectric materials for microwave communication requires low dielectric constants (εr < 10), high quality factor (Qf) and near-zero temperature coefficient of resonance frequency (τf). However, CaMgSi2O6 ceramics typically exhibit low Qf and largely negative τf, despite its low...
