摘要：
Investigations of perovskite solid solutions on basis of sodium metaniobate in NaNbO3-LaNb3O9 system have been performed. Results of the investigations make it possible to determine dielectric properties of the solutions. Dependence of temperatures of phase transitions on the compositions of the solutions have been constructed. Concentration of LaNd3O9 has been up to 20 molecular percent. Temperature range has been from room temperature to 650°C. Composition of solid solution has been detected in which concentration of LaNb3O9 has been 10 molecular percent. Dielectric constant of it has been 800 at 20-400°C.
