Abstract:
The present invention relates to a ceramic precursor composition for resorbable or partly resorbable high-strength bioelements, wherein the precursor composition comprises 40-70 wt-% of one or more silicate with Ca as the main cation, 40-20 wt- % of a Ca-sulphate, and greater than 0 wt-% to less than 10 wt-% of an acidic soluble Ca-salt, the remainder, if any, comprises additives. The invention also relates to a slurry, a cured material, a medical implant, and a carrier material for drug delivery made from said precursor composition, as well as a method of manufacturing said a cured chemically bonded ceramic material.
