摘要
For ceramic AgNb03 the occurrence of a ferroelectric phase was ascertained at temperatures less than about 75°C. In the vicinity of this temperature, the functions of dielectric permittivity ∊, loss tangent tan δ, spontaneous polarisation Ps, total pyroelectric coefficient pt and the piezoelectric coefficient d33 versus temperature were investigated. At temperature 20°C, Ps = 0.04 μC/cm2, pt = -0.1 nC/cm2 K, d33 = 0.24 pC/N.
