| The crystallochemical characteristics of polycrystalline samples, Sr1-xLaxAlO4, Sr1-xΝdxΑlO4 (x = 0.02+0.20) and Sr1-xBixNdΑlO4 (x = 0.05 ÷ 0.50) prepared by the oxalate coprecipitation and cryochemical technique have been investigated. The existence limits of single-phase states for pairs of elements Sr-Pb (x < 0.05) and Nd-Bi (x < 0.2) were determined. The microprobe X-ray analysis showed the Bi uniform distribution. The dielectric properties of pure SrLaΑlO4, SrLaGaO4 and partial replacement La → Nd samples were measured. It can be concluded that these compounds are suitable as substrate materials of HTSC thin films. |
