FIELD: chemistry.
SUBSTANCE: in fresh prepared pulp of calcium hydroxide, obtained by slaking of calcium oxide in presence of sodium hydroxide, calcium carbonate is added. From formed paste granules of composition, wt % of dry substance equivalent: calcium carbonate 66-90, calcium hydroxide 10-30, sodium hydroxide not more than 4 are formed. Quantity of water during slaking of calcium hydroxide is taken in such way that in further mixing of calcium hydroxide pulp with calcium carbonate paste with humidity 20-27% without its additional drying is obtained.
EFFECT: high structural-mechanical characteristics, sufficient sorption capacity by uranium hexafluoride, fluorine, fluoric hydrogen and considerably lower of water steams formation during catching process.
