- Abstract
- The porous filler on the basis of slurries of flotation carbon enrichment and liquid glass with high technical indicators is obtained. Studies have shown that due to the increased content of flotation concentration in the sludge (PP = 33-34 %), carbon (8.84 %), and calorific value (2800 kcal/kg), which burn out or contribute to burnout (calorific value) during firing, porosity is created in the ceramic material and a porous material with a low density is obtained, the grade of bulk density less than 400. The technology of obtaining a porous filler obtained a patent of the Russian Federation.
