With decreasing of biogenic hydroxyapatite content in initial composition from 70 to 50 wt.% the dominate phases are calcium pyrophosphate, calcium phosphate silicate and renanit. It has been shown that open porosity dominates for all prepared samples and total porosity is equal to 78-85 % depending on initial composition of the samples.
