(54) CERAMIC MASS

This invention relates to ceramics technology, in particular to compositions of masses for the manufacture of building ceramics. A known ceramic mass for the manufacture of building ceramics, including a clay component, an oxidizer, and a FlJ flux. Closest to the invention is a ceramic mass, including wt.%: A clayey substance containing minerals kaolinite and montmorillonite, 25-60; quartz sand O-ZO and flux 10 -75 f 2j. The disadvantage of this mass is the relatively high water absorption of 18.9% and the low strength of the 5.8 MP products. The aim of the invention is to reduce the water absorbency and increase the strength. This goal is achieved due to the fact that the ceramic mass, including kaolinite, montmorillonite, quartz and flux, contains these components in the following ratio, wt.%: Kaolinite31-43 Montmorillonite26-39 Quartz13-23 Plavni1O-ZO Besides, kaolinite, montmorillonite and quartz can be in the following ratio, wt.%: Kaolinite35-55 Montmorillonite - 30-5O Quartz15-30 The specified ratio is reached in. mass due to the combination of clays of different mineralogical composition, as well as the adjustment of the composition of the masses by adding clay minerals. The optimal ratio of kaolinite with a high degree of perfection of the crystal structure, montmorillonite, which is characterized by a deep imperfection of the crystal structure, and quartz makes it possible to obtain a crystalline structure during the firing process, which has a higher strength, lower permeability and 3.79 porosity than the structures of the initial components. Products made by the following technology. By combining pure minerals kao Inita, montsgrillonite, quartz and fluxes, masses are prepared, of which the press is a cozy tile of size 85.5x42.7x7.0 mm. After drying, the samples are fired in a silicon oven at 1000-1100 ° C with an exposure at a maximum temperature of 15 min. Example 1.
