Technological opportunities for improving the strength of porcelain

Quality of porcelain insulators should be improved. Increase in electrophysical and mechanical properties should be provided. In order to improve properties of porcelain, it is necessary to reduce internal structural stresses. Opportunities for reducing the stresses by means of grinding the particles have been considered. Influence of dispersion characteristic of components on properties of porcelain has been investigated. Results of the investigations have shown efficiency of addition of finely dispersed components such as quartz, feldspar into porcelain. In this case mechanical strength of porcelain is increased from 60 to 119 MPa.
