The composite materials (CM) on the base of nanocrystalline (NC) calcium hydroxyapatite Са10(РО4)6(ОН)2 (HА) (NCHА) and multiwalled carbon nanotubes (CNT), that contain 0.1; 1 и 5 w. % of CNT, in of cooperative precipitation of calcium and phosphorus salts and CNT in water systems of compositions Ca(OH)2–H3PO4–H2O–CNT produced. The influence on size, morphology and solubility of NCHA in CM HA/CNT composition, that of CNT influence on calcium phosphate mineralization simulate, were defined.
