ABSTRACT:
The present invention relates to a method of producing improved bioactive composite materials based on apatite, mainly for supporting functions in dental and orthopaedic applications, by adapting closure temperature and applying of pressure in closed systems using the production methods, according to reaction tendencies of the materials at their production, and by possibly further counteracting such reaction tendencies and tendencies for decomposition by additions of helping agents.
