Composites based on biogenic hydroxyapatite and Na2O–B2O3–SiO2 glass with the weight ratio 61 : 39 are produced. The effect of sintering temperature between 600 and 800°C on their basic properties is analyzed. To examine the effect of temperature, changes in the structure, linear and volume parameters, and density and porosity of the samples during sintering are studied. The pycnometric density of the composite is 2.904–3.009 g/cm3, apparent density 1.22–1.85 g/cm3, general porosity 36.2–59.5%, content of open porosity 0.14–0.93, and solubility in physiological solution (48 h) 0.38–1.69 wt.%. It is established that the pore structure of the composites can be controlled by variation in sintering temperature.
