Biominerals and bioceramics are widely used in medicine in replacement as well as in the process of regeneration of diseased bone tissue. Bioactive glass is known as one of the effective materials for restoring bone tissue. Dozens of bioenamel materials of different composition and purpose are known at present. Rilligate, borate and other base biomines are known, the main characteristics of which are the presence of two types of oxides, namely P2O5 and CaO in the composition of such class of glasses. At the same time, one important thing is noted - the amorphism of biotin, in contrast to ceramics of bioactive crystalline nature, provides the possibility of adjusting the ratio of CaO/P2O5 (Ca/P) present in them within wide limits. It creates prospects for the purposeful regulation of the already mentioned properties and the growth of the fields of application.
Biomin materials that are practically usaed in medicine are obtained in compositions of religiate base, when they contain 4-9 wt. % P2O5 .
Non-technological compounds such as volatile P2O5 or H3PO4, hygroscopic or refractory salts of phosphoric acids are mainly used as phosphorus-containing raw materials for obtaining such glasses.
In order to expand the obtainable raw material base of bioactive enamel, a complex, containing CaO and P2O5 (total 90 wt. %) and presented in the form of bioactive hydroxyapatite, raw material - ash obtained from cattle bone (bone ash) was selected. 6-10 wt. % P2O5 containing glasses were obtained from the charges containing bone ash, quartz sand, chalk and calcined soda, and as well as crystallized materials by their further heat treatment. Their characteristic properties are: bending strength, 390-510 MPa (MPa). Chemical stability with weight losses of 1.1-1.6 wt. % and density 2660-2740 km/m3. By summarizing the research results it was concluded that it is possible to use of beef bone ash as a raw material containing P2O5 in the production of bioactive glass materials.
