The invention relates to the production of facade cladding tiles and tiles for interior cladding of buildings with a high-speed firing mode. In order to reduce water absorption, overall shrinkage and reduce the cost of tiles, the ceramic mass contains, in wt.%: Clay component 30-40n n n perlite 10-15n n n cullet 17-20n n n tailings of flotation enrichment of antimony production 30-38. Moreover, in the clay component the ratio of montmorillonite and kaolin clay can be 1: 1.7-2. The physicomechanical properties of the facade tiles are as follows: the firing temperature is 960–970 ° C. Roasting time is 60 minutes, water absorption is 5.15-5.7%, total shrinkage is 3.5-4.0, frost resistance is more than 40 cycles. 1 tab. |
