Phosphate Glasses

Phosphate glasses, as the name suggests, consist of phosphate (rather than silicate or borosilicate) as the glass former. Calcium phosphate glasses can have a composition similar to the mineral phase of bone, which is a biological calcium phosphate (a substituted hydroxycarbonate apatite), which makes them an interesting material as a synthetic bone graft. In fact, phosphate glasses dissolve completely in aqueous solution, which offers various possibilities for their application as degradable implant materials. Therapeutic ions such as strontium, zinc or fluoride can be incorporated into the glass to be released upon degradation for stimulation of bone growth and wound healing and for prevention of infections, which can make phosphate glasses a very versatile biomaterial for tissue regeneration.
