Since the whole creep life of most materials is mainly in the second creep, Norton model has a wide range of application.
But in high temperature or under high stress conditions, Norton model can’t be applied to some materials[8-10].

This can prevent materials from being broken in the process because of no gas-liquid interface and zero surface tension.
It also retains the original structure and state of the material.
On the one hand, as a semiconductor materials, Fe2O3 has a narrow forbidden band width（Eg＝2.2eV, λ＝563nm, its absorption spectrum relatively match sun’s spectrum,it can make better use of the solar energy.
