Spinel aluminum oxynitride (AlON) has been used as ceramic materials at high temperature.
This method is widely used because of simple device, low cost and raw materials are easily obtained.
This method can quickly synthetic the MgAlON materials.
Jiping cheng[17] synthesized AlON in microwave generator from Al2O3 and AlN as raw materials.

So the question is how to choose building materials to meet the requirements. 2.
The geotechnical media widespread in nature is natural building materials.
But a considerable part of geotechnical materials are not very good building materials, deformation modulus or damping of part of the materials are not appropriate additionally, these will enlarge the seismic effect to a certain extent（＞1）.
EPS was used as antifreeze materials in Norway in 1965[7].
The core issue of soil materials is the problem of deformation and strength.

Firstly, it briefly introduces the background of creep damage for P91 materials.
To analyze the complex of creep deformation and rupture, the creep damage constitutive equations should be able to depict the behaviour of material, especially for predicting the lifetime of materials, within the frame work of continuum damage mechanics (CDM).
