In current research a new method for manufacturing of porous hydroxyapatite ceramics using highly viscous mass foaming was created. In this research hydroxyapatite synthesized by wet precipitation reaction between calcium hydroxide and phosphoric acid was used. Powder was mixed with an organic additive (polyol) to attain a highly viscous/plastic mixture. H4NHCO3 was added to the plastic mass as pore forming agent. Samples were heated by increasing temperature for proceeding the foaming process and particular release of organic additive from the sample. It was established that by varying amount of pore forming agent in the plastic mass from 0,56wt% to 1,68wt%, it is possible to achieve the porosity in range from 52 to 61% after sintering. The porosity was determined using Archimedes method. The morphology of the obtained ceramics was examined by scanning electron microscopy and phase composition was determined by X-ray diffractometry.
