Since PEG could obviously improve the dispersion stability of nano oxide materials such as SiO2, TiO2 and ZnO in water, many researchers have utilized PEG to prepare nano oxide dispersion systems and investigated the adsorption of PEG on nano oxide materials [7].
In the present work, we used pyrite powder as raw materials and different molecular weight PEG as dispersants to study the interfacial behavior of pyrite powder dispersed in PEG aqueous solution.

The permittivity of materials at deferent temperature can be measured.
The application of microwave energy is related with permittivity of materials.
So the permittivity of materials at deferent temperature can be measured.
The volume of the tested materials in the plastic tube holder was around 850 mm3.
The advantage of this technique is that it is the most accurate method for measuring low-loss materials, making it very suitable for determining the complex permittivity of low-loss materials.
