Effect of carbonate contents on the thermal stability and mechanical properties of carbonated apatite artificial bone substitute

Carbonated apatite is the inorganic component of natural bone while the carbonate ion in the structure influences biological activities and osteoconductivity. However, thermal stability of carbonate apatite is a major importance since thermal stability of carbonate apatite is a function of carbonate...
