The present invention refers to a method for the synthesis of a biodegradable calcium release material that shows controlled ion release properties for tissue engineering, biomaterials containing the calcium particles as well as the calcium particles obtainable therefrom. By varying the treatment temperature of the described method, the calcium material shows different calcium release profiles. Contrary to a specific chemical composition such as CaCO.sub.3 which is associated to a specific calcium release profile, the present invention allows a manifold of compositions, with a manifold of calcium release profiles, all starting from a single specific chemical composition calcium precursor. Therefore, the invention also relates to the use of the controllable release, calcium material in tissue regeneration such as wound healing processes.
