Abstract
There were considered the results of experimental studies on the development of the composition for the production of of wall ceramic products, including low-plastic clay of Suvorovsky deposit of the Vladimir Oblast and technogenic waste – galvanic sludge of local production. In order to improve the physicomechanical characteristics, it is proposed to introduce into the composition of the developed ceramics a modifying additive – boric acid. There was obtained a ceramic material having a significant mechanical strength (up to 2.8 MPa). An assessment of the potential hazard of samples of ceramic products was carried out on the basis of a study of the migration of heavy metals to aqueous model media and the method of of biological testing. The developed ceramic samples are environmentally safe, it is possible to use the developed composition in the production of wall ceramic products.
