Powder of calcium carbonate CaCO 3 (calcite) with a particle size of 100-200 nm and a shape close to isometric was obtained by heat treatment at 600 ° C of a product synthesized from a 2M aqueous solution of citric acid H < sub> 3 C 6 H 5 O 7 & middot; Н 2 О and commercial calcium carbonate powder CaCO 3 (calcite) with a particle size of 1 - 4 microns of a prismatic shape. The sequence of chemical transformations of CaCO 3 & # 8594; CaC 6 H 6 O 7 3H 2 O / Ca 3 (C < sub> 6 N 5 O 7 ) 2 & middot; 4Н 2 O & # 8594; CaCO 3 allows you to change the properties (size and shape) of the calcium carbonate powder CaCO 3 . Due to these properties, the obtained highly dispersed CaCO 3 calcite powder can be recommended as a filler for obtaining unique composites with inorganic (glass, ceramic, cement) or polymer matrices.
