SUMMARY:

Calcium phosphate bioceramics are a group of highly attractive materials for biomedical applications. Some of these bioceramics have special attention, they are: hydroxyapatite-Hap [Ca10 (PO4) 6 (OH) 2], which has structure and composition similar to the mineral phase of human bone (apatite) and therefore has an excellent biocompatibility, high osteoinduction enabling bone regeneration; and calcium beta triphosphate (β-TCP), which has high bioadsorption in vivo. These materials are commonly used in the form of porous grains and synthesized or porous block in different areas of health sciences such as dentistry and orthopedics. It is known that the method used for the synthesis of ceramic material strongly influences the structure of the material obtained and in the case of Hap it must be formed by nanometric grains so that its structure is as similar as possible to the biological apatite.
It was possible to produce the nanometers by combustion reaction, after being sintered by plasma if dissipated from biphases, with the presence of Hap and calcium phosphate, with Mev in those without sintering they presented clusters of fibrous shape for glycine and acircular shape for urea , after sintered acetic separation of 127nm namometric size for glycine at 1000c and 172.26 nm for glycine at 1000C, Ftir In the analyzed we can see that all bands remained, regardless of temperature, as bands were preserved because no bond was broken in front temperature increase, remaining stable at the sintering temperature of 800 ° C and 1000 ° C.
