Microwave dielectric materials in the system [formula omitted]
Dielectric properties of ceramics in the system ( Sr 1− x Ca x {( Li 1 4 Nb 3 4 ) 1− y Ti y } O 3 were investigated. In the composition range 0 ≤ x and y ≤ 0.12, dielectric permittivities and their temperature coefficients can be varied from 38.2 to 45.8 and +30 to −70 ppm/°C, respectively. In many...

were investigated. In the composition range 0 ≤ x and y ≤ 0.12, dielectric permittivities and their temperature coefficients can be varied from 38.2 to 45.8 and +30 to −70 ppm/°C, respectively. In many compositions, zero temperature coefficient of permittivity has been found. A typical compound has the following properties at X-band frequency (9 GHz): K = 42.3, 1/K· dK/dT = 0 ppm/°C and Q
