Métodos de síntesis y comportamiento térmico del Hidroxiapatito

Abstract: Este trabajo es una revisión bibliográfica de los métodos de síntesis del Hidroxiapatito (HA) más empleados: Sol-gel, mecanoquímico, hidrotérmico, sonoquímico, cerámico, hidrólisis y precipitación. Se incluye igualmente el comportamiento de los apatitos cuando son sometidos a tratamientos térmicos y se recopilan las aplicaciones que tienen los materiales de HA obtenidos mediante distintos procesos de conformado. Palabras clave: Hidroxiapatito, métodos de síntesis, comportamiento térmico, procesos, aplicaciones… Show more

“…The methods of obtaining HA are very varied, including hydrothermal systems, precipitation methods, hydrolysis, solid-state reactions and hydrothermal reactions (68)(69)(70). However, when prepared from aqueous reactions either by precipitation or hydrolysis methods, the HA obtained is usually calcium deficient (Ca/P molar ratio lower than the stoichiometric value of 1.69).…”

“…Se prepararon probetas porosas de dimensiones 35 x 15 x 3 mm por el método de la esponja polimérica (9). La composición química del material es 14% de P 2 O 5 , 28% de CaO, 50% de SiO 2 , 2% de óxidos alcalinos, 5% de Al 2 O 3 y restos minoritarios de MgO y Fe 2 O 3 .…”

“…HA due to chemical composition is very similar to the biological apatite found in hard tissues such as in teeth and bones [2]. HA is a ceramic materials that in recent years has arisen great interest in the medical field, especially for applications in orthopedics and maxillofacial surgery, as the best option for bone substitute [3][4][5], due to its excellent biocompatibility and osseoconducivity [6,7].…”
