The Pressing Process of Powders on the Basis of Siliceous Opoka-Like Rocks

The article touches upon the problem of raw materials for the ceramic industry. We have found alternative sources such as opoka-like rocks which are widely distributed in the South of Russia and the Volga region. The article presents the description of the characteristic features we identified in the process of compression molding opoka-like rocks of different types. The influence of compacting pressure on the density of pressed samples is given. There are conclusions about expediency of use of such raw materials for the development of ceramic industry.
