Temperature-stable dielectric ceramics in Pb(Mg 1/3Nb 2/3)O 3–CaTiO 3–Bi 4Ti 3O 12 pseudo-ternary system

Ceramics in the Pb(Mg 1/3Nb 2/3)O 3–CaTiO 3–Bi 4Ti 3O 12 pseudo-ternary system were investigated to search for new temperature-stable dielectrics for high frequency applications. A near-zero temperature coefficient was obtained combined with a high dielectric constant (124) and a low dielectric loss...

Summary:Ceramics in the Pb(Mg 1/3Nb 2/3)O 3–CaTiO 3–Bi 4Ti 3O 12 pseudo-ternary system were investigated to search for new temperature-stable dielectrics for high frequency applications. A near-zero temperature coefficient was obtained combined with a high dielectric constant (124) and a low dielectric loss (10 −3 at 1 MHz) where a complex phase constitution was observed. The dielectric properties were significantly sensitive to the sintering conditions due to the variation of phase constitution.
