ABSTRACT:
The present invention replaces the aluminum oxide in ALCAP ceramics with zinc oxide or zinc sulfate or mixtures thereof to provide a resorbable high strength ceramic. Specifically, a zinc bioceramic is provided comprising about 10 to 50 wt. % zinc oxide or zinc sulfate or mixtures thereof, about 30 to 40 wt. % calcium oxide and about 10 to 40 wt. % phosphorus pentoxide.
The zinc based ceramics of the present invention can be used in many of the same applications as hydroxyapatites, tricalcium phosphates and ALCAP ceramics. When mixed with a setting agent, the zinc based ceramics of the present invention are useful as surgical cements or grouts. The zinc based ceramics are also useful as hard tissue substitutes in orthopedic, dental and maxillofacial surgeries and as drug delivery devices.
