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,Leather/Silicone/PVC/ABS RFID Keychain Mini Key Fob Tag. 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,High Performance 3-Electrode Motorcycle Spark Plug A7tc.5.

The dark brown co-precipitate was separated from the initial solution by vacuum filtration after several washings with distilled water, until Cl-and SO42-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.,Empty Wide Mouth Food Storage Glass Jar with Airtight Lid, 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.
