Methods for the regeneration and further use of waste products from the production of lead crystal products - diamond cutting slimes, chemical polishing, and neutralization of acidic effluents - have been determined and tested in laboratory conditions. The use of the proposed methods provides additional economic and significant environmental effects, the possibility of producing new types of materials (complex lead-containing raw materials, low-melting glasses, foamed materials). Il. 2, bibliography: 8 titles.

It has been established that with joint mass preparation (both wet and dry), coal waste is a promising raw material for the production of ceramic building materials. The content of waste in the charge can be up to 50%. The quality of products obtained using coal mining waste in the Moscow region fully complies with the requirements of GOST 6841-84 for the corresponding products. Tab. 4, bibliography: 10 titles.

The results of the study of the possibility of using cullet of different chemical composition accumulated in landfills for the production of foam glass are presented. It has been established that sodium silicate, introduced into cullet in the form of liquid sodium glass, partially destroys the crushed cullet, averages the chemical composition of the charge and its most important technological properties. Due to the chemical interaction between the liquid sodium glass and the surface of the particles of crushed cullet, silicates are formed containing bound water, which is released at high temperatures (600 - 620 ° C) and promotes foaming of the foam glass. In the charge, liquid sodium glass leads to an increase in the amount of the glassy phase and reduces the tendency of the glass to crystallize. Tab. 2, ill. 3, bibliography: 8 titles.

The phenomenon of self-propagating crystallization (SC) is realized in the synthesis of ashes on the basis of waste from the Kansk-Achinsk basin and the possibility of using SC as a technological method is shown. The effect of the addition of fluorite, which was introduced into the charge in order to enhance the exothermic effect during sintering in the SC mode, was studied. It is shown that the use of the SC phenomenon makes it possible to reduce the duration and overall temperature of the process. Il. 3, bibliography: 5 titles.
