Polyethylene Preparing Tungsten Trioxide

Preparation Process:
Preparing various samples at different sintering temperatures after the samples were prepared, than measuring different sets of samples according to voltammeters, impedance spectroscopy and dielectric spectroscopy curves. We can obtain micron tungsten trioxide nonlinear coefficient polyethylene composite samples by calculating the nonlinear coefficients of main sample data. In the composite sample, the tungsten trioxide particles in the sample content has polyethylene nonlinear coefficients, and the nonlinear coefficient of the sintered samples, sintering the other samples at 250 ℃, up to 98%. When the organic matter content of polyethylene is 80%, the sample becomes an insulator; the prepared tungsten trioxide polyethylene material is more stable.

Sample Analysis
The experimental methods commonly is based on varistor methods, and calculating barrier trends, comparing barrier with nonlinear coefficient, typical sample is made by six-phase morphology in the structural analysis. Comparing samples with nonlinear in the function of the body as well as micro particles and nanoparticles composite sample, which shows the trends of barrier are consistent with nonlinear coefficients.

Test results of morphology and electrical properties show that polyethylene resistance and nonlinear crystal polyethylene material are applied in the electric field of tungsten trioxide samples, which resulting shift toward low-resistance crystalline phase, and it has a close relationship. The results of nonlinear of typical sample with impedance spectroscopy show the bias under the grain boundary resistance are not changed significantly. Resistance is low because their low resistances phase structures that are mainly monoclinic.
