To the 110th anniversary of the South Russian State Polytechnic University (NPI) named after M.I. Platova. The history of education, the types of activities of the department? General chemistry and technology of silicates? as part of the Faculty of Technology and the direction of training for the building materials industry. The scientific directions and research results of the employees of the department are presented.
Optimal compositions for the synthesis of foam glass with the use of slag waste from thermal power plants have been developed? foam slag glass. Based on the experimental data, a program has been created for modeling the foaming process, which makes it possible to establish the structure of foamed slag glass without carrying out additional experimental studies.
The possibility of using ash and slag waste from thermal power plants in the production of heat-insulating glass materials has been established. Compositions with different granulometric composition of the charge have been developed, and heat treatment has been carried out. The main properties of the synthesized samples were determined, the effect of particle size on the foaming of granules and the optimal dispersion of the charge was established.
Based on the R 2 O? BaO? TiO 2 ? SiO 2 system (where R 2 O? Li < sub> 2 O, K 2 O and Na 2 O) glass with low crystallization capacity has been developed; the value of the tangent of the angle of dielectric losses equal to 0.0035; density 3388 kg / m 3 ; TCLE, amounting to 84.5 · 10? 7 K? 1; the minimum absorption of radio waves in the ranges of 8? 11.3 and 26? 35 GHz
