Perkin-Elmer DSC 204 F1 Phoenix apparatus with α-Al 2 O 3 powder as the reference material. The structure and crystallite sizes of the prepared sample and its decomposed product were studied by X-ray powder diffraction using a D8 Advanced powder
in Pt crucibles, and α -Al 2 O 3 was used as the reference material. Measurements were performed using a dynamic nitrogen furnace atmosphere at a flow rate of 50 mL min −1 . Different heating rates were chosen as 5, 10, and 15 °C min −1 , and the
-isothermal linear regimes. Sample from 3 to 4.5 mg, placed in α Al 2 O 3 crucibles, were heated from room temperature up to 800 °C (experiments in air) and up to 1,000 °C (experiments in argon) using a horizontal “Diamond” Differential/Thermogravimetric Analyzer

Synthesis, thermal and other properties
techniques; TG, DTG, and DTA curves were recorded on a derivatograph (type Q-1500) using samples of 100 mg with α-Al 2 O 3 as reference material in static air atmosphere. From TG, DTA, and DTG curves, solid intermediate products are determined and confirmed
Low temperature reactivity in agglomerates containing iron oxide
Studies in the Ca(OH)2–C–Fe2O3 system
samples shown in Table 1 using heating from 293 to 1,073 K at either 2, 10, or 32 K/min in helium with a constant flow rate of 60 ml/min. Cylindrical α-Al 2 O 3 crucibles with a diameter of 4 mm and a capacity of 100 μl were used in these tests. Select

Utilization of the products as adsorbents for oil spill cleanup
increasing temperature from ambient to 1073 K. The measurements were performed in dry air atmosphere, at a heating rate of 10 K/min. The sample mass was about 10 mg placed in an aluminium crucible without pressing. Calcined α -Al 2 O 3 powder was used as
monomers and environmental issues. Materials and experimental procedure The research has been carried out on alumina powder α-Al 2 O 3 Nabalox 713-10 (Nabaltec, Germany) of mean particle size D 50 = 0.70 μm and selected
apparatus (Shimadzo thermal analysis system, model TA-60WS). A total of ~20 mg of the samples were heated in an aluminium crucible in nitrogen atmosphere up to 1000 °C, maintaining 10 °C/m heating rate and using α-Al 2 O 3 as the reference material. The XRD
