Phase diagram and single crystal growth of (La, Sr)2CuO4 from CuO solution

The system (La,Sr)2CuO4-CuO has been investigated by differential thermal analysis (DTA), thermogravimetric analysis (TGA) and slow-cooling flux growth experiments. The phase diagram is given and was used in the crystal growth experiments. The crystal products have been characterised by EPMA and by X-ray powder pattern and single crystal techniques. Large single crystals have been grown from CuO as flux by spontaneous nucleation and top seeding.
