According to the different calcination temperature, the resulting alumina crystal structure and surface area are different, mainly α-Al2O3 and γ-Al2O3.
As shown in the patterns, the crystal structure and crystal phase of the product resulted from aluminum hydroxide calcined at 900°C for 3 hours is similar to γ-Al2O3.

The properties of each volume of 100 3 voxels in size have been computed according to the method described above, in the Knudsen and the ordinary regime, and compared with results in ideal (ordered and random) fibrous structures [15,16].

However, the inferior corrosion resistance attributed to high chemistry activity of Mg limits their widespread application [1-4].
In general, the structure of Mg alloys can be refined by two approaches.

Such silane agents enable the fixation of molecules covalently to surfaces, and different functional groups may be part of the molecular structures anchored [6-7].
The resulting samples were characterized for structure by X-ray diffraction.

In YPO4:Eu3+ structure, Eu3+ ion takes proper side of Y3+ ion due to this enhanced luminescence intensity and has also been widely used for various applications [9].
Also the XRD shows that the formed material was completely crystalline and was in single phase with tetragonal structure, where a = b = 6.881, and c = 6.017.

Air cooling system needs fan, air deflector and made the structure complex and the fan which consumes large amounts of electricity.
Since the battery on the structure have symmetry and reference to the model in[5],the model can be simplified and we can select one unit as the research object (Fig. 1b).

It depends in a complex way on the composition, structure and state of grain boundaries and phases formed under the influence of a specific heat treatment.
The structure and phase composition of the aged alloy is also determined by the type of decomposition of the quenched solid solution, the sequence of nucleation and growth of intermediate phases formed upon aging, and their selective interaction with the magnetic field. 3.
