A New BaO-TiO2 Compound with Temperature-Stable High Permittivity and Low Microwave Loss
The dielectric properties of ceramics in the TiO2‐rich region of the BaO‐TiO2 system were investigated. In the composition range between BaTi4O9 and TiO2, another compound, Ba2Ti9O20, can be obtained when calcining and sintering conditions are controlled carefully. When dense and single‐phase, this...

| description | The dielectric properties of ceramics in the TiO2‐rich region of the BaO‐TiO2 system were investigated. In the composition range between BaTi4O9 and TiO2, another compound, Ba2Ti9O20, can be obtained when calcining and sintering conditions are controlled carefully. When dense and single‐phase, this ceramic has excellent dielectric and physical properties. At 4 GHz, the dielectric K= 39.8, Q= 8000, and τK (temperature coefficient of dielectric constant) =−24 ± 2 ppm/°C. |
