Materials Review.

Concrete can be classified as quasi-brittle materials which is the same as ceramics, rocks, some polymers, mortar and wood [4].
It can also be considered as a heterogeneous and multiphase materials [4].

Introduction The permanent magnet materials have already been used extensively in the filed of Electric Machine ,Electric Apparatus, Communications, Control Science and Power Electronics.
With the continuous improvement of the performance of permanent magnetic materials and the emerging of new permanent magnet materials are emerging.
The magnetization of permanent magnet materials is one of the problems need to be resolved.
With the improved performance, the coercivity of permanent magnet materials is increasing.

The starting materials were mixed and melted in air at 1480℃ in an electric furnace.
Unfortunately, due to miss the reference materials in which S2- is bonded to silicon and be unable to distinguish the influence of iron sulfide complexes from the XANES spectra of glass, we were unable to determine which cation or cations coordinated with the S2-.
