1) of the samples added with Fe2O3 and MgO are the highest;and at the same holding time of temperature,the density and thermal conductivity increase along with the increment of the sintering temperature;at the same temperature,both of them increase along with the extension of the holding ...
The reactivity of iron(III) oxide was investigated also in other reactions: solubility in HCl and catalytic decomposition of H2O2.On the basis of density and electric conductivity data the high reactivity of Fe2O3exhibited between 675 and 700°C was interpreted by the great increase of iron ...

Incorporating high-thermal-conductivity fillers is the most adopted approach for enhancing the thermal conductivities of PCMs [196]. High-thermal-conductivity fillers mainly comprise metal-based materials (copper [197,198], nickel [199], silver [79,200], Al2O3 [201,202], and TiO2 [203,204]...
Photopyroelectric simultaneous measurements of the specific heat, thermal diffusivity, and thermal conductivity of single-crystalline FeF2 at the antiferromagnetic-paramagnetic phase transition have been performed. An Ising-like behavior has been found for the specific heat for ‖t‖≤1.2×10-2, while,...
A detailed investigation of the phonon-spin interaction in the system Ni3+:Al2O3 has been carried out by low-temperature thermal conductivity measurements on single crystals (0.05 to 100K). Using the theoretical model of Abou-Ghantous et al. (1974) to describe the vibronic energy levels, a ...
electrical conductivity technique under the same atmospheres. Under all the above atmospheres, the thermal dehydration was found to be a two-step process. However, the thermal decomposition process was quite complicated, involving the formation of various metastable intermediates, including γ -Fe 2 O...
