Among the biomaterials based on calcium phosphate, hydroxyapatite has been widely used due to its biocompatibility and osteoconduction. The substitution of the phosphate group by the carbonate group associated with the absence of heat treatment and low synthesis temperature leads to the formation of carbonated hydroxyapatite (CHA). The association of CHA with other metals (strontium, zinc
Ionic Conductivity of Pure Solid Calcium Sulfide
Calcium sulfide disks have been carefully prepared to avoid any contamination by means of a newly-developed sintering method. The electrical conductivity has been measured at temperatures from 923 to 1173 K and in the P H 2 S ⁄P H 2 range from 0 to 10 2 with the aid of an alternating current bridge.
