Autor: Luiz Carlos Pereira, Lilian Fernanda Santos Paiva, Marize Varella de Oliveira, Alexandre Antunes Ribeiro, Omayra Beatriz Ferreiro Balbuena, Magna Monteiro

Publikováno v: Ceramics International. 47:32979-32987

In the sintering of biphasic calcium phosphate bioceramics (BCP) can occur phases transformations accompanied by a sudden thermal expansion due to different coefficients of thermal expansion of each phase, which generates internal stress concentratio

Publikováno v: Materials Science Forum. 899:254-259

The calcium phosphate bioceramics are widely used for the bone reconstruction because of their mineralogical similarities. This work aimed to obtain a biphasic calcium phosphate from hydroxyapatite nanoparticles synthesized by sonochemical technique

Ceramic materials mimic the mineral composition of native bone and feature osteoconductive properties
they are therefore used to regenerate bone tissue. Much research focuses on increasing the porosity and pore interconnectivity of ceramic scaff
