PREPARATION, CRYSTAL STRUCTURE, AND DIELECTRIC PROPERTIES OF NEW SOLID SOLUTIONS (Pb1–2xWx)O1+x (x ≈ 0.05) BASED ON THE TETRAGONAL FORM OF LEAD OXIDE
Single crystal X-ray diffraction (XRD), thermogravimetric, and dielectric studies are performed for single and polycrystalline samples of [(1– x )PbO + x WO 3 ], 0≤ x ≤0.20, synthesized by solid phase reactions and crystallization of melts. The formation of previously unknown solid solutions base...
