Effect of cullet on firing temperature and dielectric properties of ...
The porcelain insulator prepared from the composition of 45%clay, 35%feldspar, 10%quartz and 10%cullet and fired at 1200 °C showed dielectric strength /mm, water absorption (%), apparent porosity (%), bulk density ( g/cm 3), and linear shrinkage (%). Therefore, incorporating economic alkaline materials such as cullet to ...
