“…Moreover, the DTG is a thermal analysis wherein the exothermic (energy released)/endothermic (energy absorbed) or thermogram peaks will be considered. [33][34][35][36][37][38][39][40] Using these peaks, one can identify the hydrate ion removal temperature, decomposition of metallic/non-metallic, and residual species of sample. The TG-DTG plots of x = 0.2-0.8 nano-hexaferrites were shown in Figure 14.…”

BaxCo1‐xFe12O19 (x = 0.2, 0.4, 0.6, & 0.8) nanoparticles are prepared via hydrothermal method. The hexagonal structure of x = 0.2 – 0.8 samples is confirmed by X‐ray diffraction patterns. Morphology indicated the existence of nanospheres like grains. The magnetic and dielectric parameters are clearly discussed as a function of composition at room temperature. The increase of Ba‐content reduced the magnetization from 56.1 to 49.7 emu g−1, and at higher Ba‐content, it is increased from 49.7 to 57.3 emu g−1. The x = 0.6 content offered the high ε' ≈9.54 and low ε" ≈0.12 values suitable for charge storage, and low noise device applications. Further, the thermal properties (using thermogravimetry (TG)‐differential thermogravimetry (DTG) & TG‐differential scanning calorimetry (DSC)) are elucidated in detail.

In the presented work, high purity yttrium oxide (99.99%), nanosized crystal density 0.069 g/cm3, specific surface area 100-150 m2/g, average crystal size 8-10 nm and difrent intensities (4.0×10 12 n/cm2, 1.3×10 13 n/cm² and 4.0×10 14 n/cm²) in the temperature range of 300-700 K, the electrical properties were investigated after irradiation with fast neutrons. It has been established that the electrical properties of Y 2 O 3 nanocrystals in a wide temperature range show an increase in the electrical conductivity according to a linear law after irradiation of various intensities. The increase in conductivity depending on the intensity of fast neutron radiation is due to the predominance of yttrium vacancies in the conductivity.

Herein, the crystal structure, surface morphology, and magnetic and thermal properties of the BaFe11.9In0.1O19‐substituted M‐type hexaferrite are investigated. This solid solution is fabricated using “two‐step” topotactic reactions. It is determined through the X‐ray diffraction method that the crystal structure of this solid solution under normal conditions has hexagonal symmetry with P63/mmc space group (No. 194) with the unit cell parameters a = 5.8992(1) Å and c = 23.2275(7) Å. It is determined by the scanning electron microscope (SEM) researches that the average size of the grains is true d ¯ = 6 μm. It is determined by the vibration magnetometry that the ferrimagnet–paramagnet phase transition happens at around T C = 420 °C. Using differential scanning calorimetry (DSC), it is found that air and water molecules leave the sample surface up to 420 °C and the resulting oxygen anions appearing as a result of a solvothermal reaction fill the oxygen vacancies in the crystal structure at high temperatures up to 800 °C. The thermal transitions repeated in the high temperatures are established. The oxidation behavior of this compound is determined from thermogravimetric analysis (TGA) in a wide temperature range.
