Sonoelectrodeposition technique has been used to prepare bioactive brushite coatings on carbon/carbon composites.

The observation of Ca/P ratio changes in dentin after tooth bleaching with 30% hydrogen peroxide;

Studies on the need of energy and protein and calcium and phosphorus of lactating buffaloes in the lactating period;

Biodegradability and bone-forming effects of CP(calcium phosphate porous ceramics) and CPB(calcium phosphate-bone morphogenetic protein porous composite) in vivo as well as microstructure of the interface between biomaterials and new bone were investigated by roentgenogragh, SEM and EPMA.

The design of biomaterials based on calcium phosphate is a prospective way to develop high-performance hard tissue repair materials for clinical treatment.

It has been deeply believed that the formation of the bone-like apatite containing carbonate in the calcium phosphate ceramics is important to the growth of the new bone and the osteoinductivity of the materials.

At present, many researches have been carried out to study the calcium phosphate ceramics without carbonate.

To explore a novel diphase Ca-P scaffold material which had good bioactivity and long-term osteogenesis,a pure HA scaffold coated with diphase calcium phosphate ceramics film was prepared by sol-gel method.
