FIELD: chemistry.
SUBSTANCE: broken glass is milled in ball or any other mill to specific surface 6000-20000 cm2/g. Hydroxilation of broken glass is carried out in the process of milling for 30-60 minutes. Diatomite is simultaneously milled to particle size 250-300 mcm. After that, milled diatomite separately or in mixture with milled broken glass is subjected to mechanical activation for 1-5 minutes in planar mill. After that, porophore, containing glycerol and solution of liquid glass, and water are added until plastic paste with mass humidity 15-18% is obtained. Granules are formed, dried at temperature 100-150°C to humidity 2-5%, then, burnt in furnace at temperature 750-800°C.
EFFECT: simplification of production technology.
