CREATION OF FUNCTIONAL CERAMICS BASED ON MINERAL RESOURCES

In this work, the composition and technologies for producing composite ceramics based on clay and powdered mineral resources of the southern region of the Kyrgyz Republic have been developed. The objects of study are the clays of the Toloikonskoye and silicon oxide of the Ozgurskoye deposits in the south of Kyrgyzstan. It is shown that the introduction of a filler (silicon oxide) into the matrix in an amount of 6 wt. % and firing the sample at a temperature of 10000C provides an average ceramic density of 1956 kg/m3, at the same time, the water absorption of the CMC decreases from 15.7% to 8.7%, and the compressive strength becomes maximum and amounts to 43.6 MPa. It was revealed that when choosing a clay raw material and a filler for creating a specific ceramic, it is necessary to evaluate the physicochemical properties of clay rock and silicon oxide (granulometric, material and mineralogical compositions, impurity components, etc.) silicon oxide component makes it possible to obtain a durable CMC using a semi-dry technology at a firing temperature of 1000 °C.
