Abstract

A long-term stable material, which has two main crystalline phases – fluorapatite (FA) and calcium zirconium phosphate (CZP) [1, 2] and could be processed to dense sintered samples was tested related to the use with two application forms – spongiosa-like specimen and foils. The suitability of various sintering additives was investigated alone and in diverse combinations. During sintering of the spongiosa-like samples volume shrinkage of about 50% was observed whereas the shrinkage in x,y plane was about twice of the shrinkage in z direction. The cuboid form was not affected by the shrinkage. The compression strength of the spongiosa-like materials was in the range of 1MPa up to 1.6MPa. A ceramic foil was generated via foil slip casting of a slip containing about 38vol% of FA-CZP. Temperature programs were created for debindering and sintering of the green foil and the four-fold laminate, respectively.
