The process of pore formation and volume changes at liquid-phase sintering of two compositions of hydroxyapatite/glass composites with nanostructured-hydroxyapatite content of 40 and 60 wt.% is investigated. As revealed, the process of material foaming during heat treatment is the main cause of formation of complex porous composite structures. Macrochanges of surface and bulk of samples, which appear as a loss of their form and formation of bubbles, and microchanges with transformation of pore structure from opened to closed one take place in the process of foaming.
