Abstract
The present invention discloses a method that can improve the sintering ability of calcium sulfate. The material can be used as a bio-material. This method is prepared by pre-mixing +1 and/or +2 and/or +3 and/or +4 and/or +5 valence element and/or its chemical compounds which serves as a sintering additive to calcium sulfate. During sintering, the sintering additive may form a compound and/or a glass and/or a glass-ceramic to assist the densification of the calcium sulfate. The strength and biocompatibility of the specimen after sintering are satisfactory.
