Method for producing nanosized calcium hydroxide crystals or particles, according to which method the calcium oxide-bearing initial material is brought into contact with carbon dioxide in the aqueous phase. Calcium carbonate crystals or particles are produced in a mixture, the pH of which is below 7. Using the present invention, it is possible to combine the two stages of producing CaCO3 particles into one entity, in which case the overall processing time is shortened and the use of external energy is minimized.
