Introduction The degradation of the ferrite core by severe temperature changes is caused to transformation of Fe-C lattice structure.
The ferrite is BCC structure, but it is changed the by high temperatures to the FCC structure.
These microscopic deterioration occurs into the Ferrite internal a change of the lattice structure.

XRD and Raman confirm the CZTS structure and the impurities on the surface are removed after suitable chemistry treatments.
The structures of the metallic precursors are investigated by XRD (Rigaku Co., TTR3).
The grains seem to recrystallize and/or form some amorphous structures.
Grains are large and closely packed and present similar structure to Fig.6.b.
With suitable chemistry treatments these impurities are removed.

It can be used to manufacture interior structures for airplanes and high-speed trains or other applications with flame retard requirement.
If the temperature is too low or the heating time is too short, the volatile of the prepreg will be too much to make a low void content composite structure.

The influence of the europium concentration on the structure, morphology and luminescence characteristics of the ZnO powders was investigated.
The proportion of each reagent and fuel was calculated based on the propellants chemistry concepts.
The structure of the zinc oxide is relatively opened and, therefore, it becomes relatively easy to incorporate dopants impurities in its lattice [2].
The influence of the europium concentration on the structure, morphology and luminescence characteristics of the ZnO powders was investigated.
The proportion of the reagents was initially calculated in accordance with the concepts of the chemistry of propellants, with fuel excess (φ < 1) [15] (100% in fuel excess were used).
