PROCESS FOR OBTAINING BIPhasic BIOCERAMICS BASED ON CALCIUM PHOSPHATE FROM MARBLE WASTE

摘要

the present invention patent refers to a process for obtaining nanoparticles of biphasic bioceramics based on calcium phosphate with average crystallite size in the range between 42.56 and 57.55 nm. the process, object of the present invention patent, provides binary mixtures of the type ß-ccp (ß-ca2p2o7, ß-calcium pyrophosphate) / magnesian whitlockite ((camg) 3 (po4) 2), synthesized via simple precipitation method using marble residue from the ornamental stone industry's production chain as an alternative and ecologically sustainable raw material. these nanometric powders of biphasic bioceramics based on calcium phosphate are widely used in biomedical applications.
