2. Experimental Procedure

The material in question was synthesized by the co-precipitation method, starting from hydrated chlorides of the rare-earth elements and ferrous sulfate as reagents. These solutions were all mixed together in a container,2.5mm Low Carbon Steel Mild Soft Wire. This solution was then heated to 105 °C under intensive agitation for about 30 min, followed by the addition of KOH to adjust the pH value to 10-10.5 range, while allowing for the easy elimination of the K⁺ions by washing the precipitate with distilled water⁷. A thermodynamic analysis⁸indicated that, for co-precipitation to occur, the final pH should range from 9 to 12; therefore,Decoration Artificial Bonsai Succulent Plant Plastic Synthetic Topiary Boxwood Vertical Garden Green Wall.5.

The dark brown co-precipitate was separated from the initial solution by vacuum filtration after several washings with distilled water, until Cl^-and SO₄^2-anions were no longer detected in tests based on reactions with AgCl and BaSO₄, respectively⁹. The precipitate was dried following Reed's recommendation¹⁰, i.e.,Custom UV Ink Printing Security Paper Booklet, followed by heating to 75 °C for 4 h. The dried co-precipitate was then milled in an agate mortar and thermally analyzed¹¹(Shimadzu 50H Differential Thermal Analyzer and Shimadzu TGA-50 Thermogravimetric Analyzer).

Subsequent calcination¹²of the coprecipitates was performed under the conditions suggested by the thermal analysis, i.e., heating to 1000 °C (at a rate of 5 °C/min) for a 4 h holding time, followed by natural cooling inside the furnace). Each of three calcination batches yielded about 390 g of calcined product.
