FIELD: chemistry.
SUBSTANCE: invention relates to heat-insulating materials. Foamy slag glass contains the following components, wt %: slag TPP - 60-70, boric acid - 10-20; chalk - 1-5; broken glass - 15-25.
EFFECT: extension of raw material base, reduction of cost, utiliation of ash-slag wastes of TPP, reduction of foaming temperature to 900-950°C and simplification of technology of obtaining foamy slag glass.
