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,Aluminum Die Cast or Aluminium Die Casting Parts/China Customized with OEM Service. 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,304 316 321 Bright Annealing Stainless Steel Seamless Tube Manufacturer..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.,Measuring Wheel Dia. 15.9cm, Perimeter Is 99.99999cm, 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,ERW Steel Tube Q235, 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,160A CNC Plasma and Flame Metal Cutting Machine(the amorphous phase) into the crystalline samarium, holmium and iron (III)for Oil Fields Clay Stabilizer.
