FIELD: chemistry.
SUBSTANCE: method of producing calcium aluminate involves mixing calcium hydroxide with aluminium metal powder, where water is added in amount of 19 to 40% of its content in the mixture at the mixing step. The obtained mixture is mechanically activated, and the obtained product is thermally treated once at temperature ranging from 700 to 900°C.
EFFECT: increased specific surface area in 1,57-1,67 times, cutting on number of process steps, prevention of formation of waste water.
