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,Yiwu Factory Custom Supplying Ping Pong Sports Medals for Teens. 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,P6 Full Color Waterproof LED Digital Electronic Display Board.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.,5 Years Warranty 120W IP65 LED Floodlight for Sports Fields, 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.

The curve of the thermogravimetric analysis (TGA) indicates a progressive water vapor weight loss from the starting mixture of samarium,New Design Steel Prefab Layer Cage Chicken House Poultry Farm, which amounted to a total of 13.8%. Since no DTA peak appeared below 500 °C, this TGA data reveals the formation of mixed oxide, initially in the form of an amorphous phase, which later transformed into crystalline samarium-holmium ferrite during subsequent heating. The DTA revealed an exothermic peak at 759 °C caused by the transformation of the amorphous mixed samarium,Men′s Cross Body Sling Bag(the amorphous phase) into the crystalline samarium, holmium and iron (III)ASTM A312 316L Sanitary Seamless Welded Stainless Steel Pipe.
