Abstract
Lanthanum cuprate (LCO) was synthesized from lanthanum and copper precursors in molten sodium nitrate–potassium nitrate eutectic. The chemical reactions were studied by thermogravimetric analysis and X-ray powder diffraction was used to identify the crystalline phases. The chemical reactions of copper and lanthanum precursors in alkaline nitrate eutectic were studied and the basicity of the reaction mixture was increased in order to precipitate the crystalline mixed oxide. Scanning electron microscopy investigation has shown the obtaining of lanthanum cuprate as large platelet crystals of quadratic shape. The synthesis conditions are favourable for a direct formation of a superoxygenated lanthanum cuprate, La2CuO4 + δ .
