Microstructural and decomposition rate studies of periclase …
2011年3月15日 · Microstructural characterization using XRD and EDS elemental mapping on periclase-added aluminum titanate–corundum functionally-graded materials produced by the multiple infiltration method has been performed to observe the formation of Al 2(1−x) Mg x Ti 1 + xO 5 solid solution in the phase-compositionally changing materials. XRD data and ...
2. XRD patterns of the 60 min ground mixtures calcined at …
When the calcination temperature went up to 800 o C, several bumps in the XRD patterns were observed. These bumps were attributed to the periclase and spinel phases (Figure 5.2). Further...
XRD patterns of specimens A 16.5 sintered at different …
When the sintering temperature is 1000°C, the phases of specimen A 16.5 are periclase in majority, and minor spinel and corundum. When the sintering temperature increases to 1400°C, the...
present paper describes an X-ray diffraction (XRD) method accompanied with chemical treatment such as acid treatment and ashing for the determination of rutile
High-temperature thermal expansion of lime, periclase, corundum …
The high-temperature cell parameters of lime (CaO), periclase (MgO), corundum (Al 2 O 3), and spinel (MgAl 2 O 4) have been determined from 300 up to 3000 K through X-ray diffraction experiments with synchrotron radiation. The good agreement found with dilatometric results suggests that vacancy-type defects do not make a large contribution to ...
Thermal and physical properties of spinel, periclase and corundum …
XRD determined the presence of BaO·Al2O3 at 1000 °C and the formation of Ba-β-Al2O3 at 1600 °C.
spinel-cristobalite mix of cordierite composition. a decrease in intensity at lower temperatures, usually about 1200" C. to 1250" C. These factors suggest that the first formation of cordierite at 1300' C. is the result of the reaction of periclase and corundum with silica, and that the break in the cordierite curve is due to the reaction of
CN103995012A - Method for testing content of periclase in …
The invention belongs to the technical field of X-ray diffraction (XRD), and discloses a method for testing content of periclase in cement clinker and cement paste via XRD. The method...
It is applied to give the temperature dependence of Cv over the range 0ø-I000øK of halite, periclase, brucite, corundum, spinel, quartz, cristobalite, silica glass, coesite, stishovite, rutlie, albite, and microcline. The specific heat of the simple Debyelike substances, halite and periclase, is reproduced well by the model.
