The use of anthracite flotation wastes in ceramic masses based on waste fused rock—intershale clay—without the application of traditional natural materials makes it possible to obtain structural insulation materials with thermal conductivity and density of <0.20 W m−1 K−1 and 1200 kg/m3, respectively. © 2014, Allerton Press, Inc.

The paper is devoted to the study of a boundary-value problem for an equation of mixed type with generalized operators of fractional differentiation in boundary conditions. We prove uniqueness of solutions under some restrictions on the known functions and on the different orders of the operators of generalized fractional differentiation appearing in the boundary conditions. Existence of solutions is proved by reduction to a Fredholm equation of the second kind, for which solvability follows from the uniqueness of the solution of our original problem. © 2016 by De Gruyter.

A dependence is established for acid-resistant material pore structure on firing temperature and gas parameters. It is expedient to fire acid-resistant materials up to 1100°C in an oxidizing atmosphere, and at 1100 – 1200°C in a reducing atmosphere. With this regime firing provides an improvement for acid-resistant material pore structure. © 2016, Springer Science+Business Media New York. Source
