FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing precipitated silicon dioxide, which includes reacting a silicate with an acidifying agent to obtain a suspension of precipitated silicon dioxide (S1), a separation step to obtain a cake, a step of disintegrating the said cake to obtain a suspension of precipitated silicon dioxide (S2) and drying the said suspension. According to the method, the disintegration step is carried out in a hot state at a temperature of 50 to 120°C.
EFFECT: high output and cost effectiveness of the method while preserving the quality of the product.
