The paper presents the fundamental possibility of using ash and slag waste (ASW) of the fuel and energy complex in the production of ceramic bricks using the semi-dry pressing method based on the Buguruslan deposit low-melting aluminosilicate loams. The technological parameters optimization ways (molding moisture, grinding fineness, pressing pressure) in the production of ceramic bricks from low-quality clay raw materials using the experiment mathematical planning method are presented. The separate and joint grinding raw materials mixture rational composition influence on the ceramics technological properties is studied.

This paper assesses the moldability of press-powder with different fractional composition. Different types of defects that occur in ceramic materials due to insufficient or overpressure of molding of press powderare analyzed. Based on results of structural studies and evaluation of the physical properties of materials recommendations on the molding selection modes of press-powders with different fractional composition that provide the absence of defects in the compacts and obtaining quality dense ceramics are formulated.

The object of the research is the firing temperature of ceramic materials based on barium titanate. In laboratory conditions, barium titanate was synthesized from raw materials of barium carbonate and titanium dioxide using ceramic technology, taking into account the stoichiometric composition of the compound. In order to study the effect of the firing temperature on the properties of the ceramic material, three temperatures were selected: 1270, 1300, and 1350 °C. The physical properties of the samples (imaginary density, water absorption, open porosity) were determined by the method of hydrostatic weighing in water. The samples were saturated with water after their preliminary evacuation. The dielectric characteristics of the obtained materials were measured on an E7-8CLR automated device (Ukraine) at a frequency of 1 kHz. The structural and morphological features of ceramics based on synthesized barium titanate were investigated by direct scanning electron microscopy and X-ray phase analysis. On the basis of the complex of studies carried out, the technological parameters of the production of ceramics were selected. Thus, the duration of grinding at the first and second stages is 10 and 30 minutes; moisture content of the press powder – 8 %; pressing pressure – 20 MPa; temperature of the first firing – 1000 °С; temperature of the second firing – 1350 °C. The regularity of the change in the dielectric constant on the firing temperature of ceramics based on barium titanate was established. The investigated samples, obtained according to the given technological regime, are characterized by the following indicators: dielectric constant – 259.9; open porosity – 0.02 %; water absorption – 0.01 %; imaginary density – 5.45 g/cm3. The resulting material can be used to create composite ceramic materials that protect biological and technical objects from the effects of electromagnetic radiation, and can also be used to create new functional materials for space, aerospace, electronic engineering and medicine.
