AB  - Nanopowders of hydroxyapatite (HA), modified by magnesium (MgHA) and by silicon 
      (SiHA) were obtained by liquid-phase microwave synthesis method. X-ray 
      diffraction and IR spectroscopy results showed that Mg(2+) and SiO(4)(4-) ions 
      were present in the synthesized products both as secondary phases and as part of 
      the HA phase. Whitlockite was found in the magnesium-modified HA (MgHA) and 
      larnite was found in the silicon-modified HA (SiHA); ion substitution for both 
      materials resulted in solid solutions. In the synthesized samples of modified HA, 
      the increase of particle size of powders was in the order HA < SiHA < MgHA, which 
      was calculated through data specific surface area and measured pycnometric 
      density of the powders. The Lewis acid sites (Ca(2+), Mg(2+), Si(4+)) were 
      present using spectral probes on the surface of the samples of HA, MgHA, and 
      SiHA, and the acidity of these sites decreased in the order SiHA > MgHA > HA. The 
      rates of calcium phosphate layer deposition on the surface of these materials at 
      37  degrees C in the model simulated body fluid solution showed similar dependence.
