Abstract

The present invention relates to a powder mixture for resorbable calcium phosphate biocements, which mixture consists of 40–99% by volume of powder having a particle size of 0.1–10 μm, 1–20% by volume of powder having a particle size of 10–43 μm and 0–59% by volume of powder having a particle size of 43–315 μm, which powder is obtained by grinding the spontaneously crystallizing melts of a material comprising crystalline and X-ray amorphous phases, which material
