Clays of the Maloarkhangelskoye Deposit are Promising Raw Materials for Ceramic Materials

The results of the study of light- and dark-burning refractory clays of the Maloarkhangelsk deposit in the Oryol region for the production of ceramic materials are presented. The chemical, mineral and granulometric compositions have been studied, the pre-firing and firing properties of the raw materials have been determined, the change in the color of the shard is given depending on the firing temperature in an oxidizing environment for two types of clays. The logistical advantages of the «Orlovskaya Keramika» deposit for brick factories in the European part of Russia are considered. Studies have shown that the clays of the Maloarkhangelsky deposit are very promising as the main raw material and an additional component for the production of facing ceramic bricks of various shades, wall and road clinker, hand-molded bricks, ordinary solid bricks, and ceramic blocks. The quality indicators of raw materials make it possible to use it as the main component of the charge, as well as an additive to improve the drying and roasting properties of products.
