FIELD: technological processes.
SUBSTANCE: invention relates to a technology for the manufacture of ceramic proppants and can be used in the oil and gas industry as proppants in the production of oil or gas by hydraulic fracturing of the formation – fracturing. In a method for producing ceramic proppants, which comprises forming droplets from concentrated slurries, curing, drying and calcining them, curing is carried out by dispersing the droplets into a powder having a refractoriness equal to or greater than the refractoriness of the solid component of the slurry. Invention is developed in a subclaim.
EFFECT: increased strength characteristics along with maintained high sphericity.
