Structure of white calcium phosphate was characterized for the first time.  Italian study characterizes the structure of white calcium phosphate for the first time.

 

The Crystallographic Institute (CNR-IC) of the National Research Council of Italy (CNR-IC) conducted a study in cooperation with Rome One, Rome Three, and the British ISIS pulse meson and neutron source to analyze the structure of whitlockite in detail, and For the first time to obtain a complete characterization, this research will also help to improve the performance of biomedical materials. Related papers were published on “Crystals”.

White calcium phosphate is a rare natural calcium phosphate found in terrestrial granite rocks and chondrites, and can be used as a natural substitute for synthetic tricalcium phosphate.

Synthetic tricalcium phosphate is a biological material used in fillers and coatings in orthopedics and dentistry. Synthetic tricalcium phosphate is an alternative to synthetic hydroxyapatite, which is very similar to the mineral composition of human bones and teeth, but in some cases (for example, used as a bone prosthesis) behaves very fragile.

Researchers are conducting preliminary analysis of the white phosphorite by X-ray diffraction, using neutron diffraction to locate hydrogen atoms, using electron probes to confirm its chemical composition, and using infrared spectroscopy to supplement the diffraction results.

The researchers said that based on the study of natural materials, the performance of similar synthetic materials can be further improved, their fragility and the risk of rejection when used as a prosthesis can be reduced, thereby improving the safety and overall performance of the prosthesis, and better Used in biomedicine and other fields.
