Hidroxiapatita formula


Hidroxiapatita deficientă in calciu (CDHA) cu formula Ca10-x(PO4)6-x(HPO4)x(OH)2-x, 0≤x≤1 Fosfații de calciu: fosfat tricalcic (TCP, prezent in formele cristalografice α si β), fosfat dicalcic (DCP), pirofosfatul de calciu. Biocompatible materials development for the replacement of human body parts has been one of the needs of science. Hydroxyapatite is a bioceramic similar to the mineral component present in the human hard tissues and animal body. In this work, hydroxyapatite nanorods were synthesized and ... El esmalte dental o t ejido adamantinado , es una cubierta de gran pureza, compuesto por Hidroxiapatita, mineral más duro del cuerpo humano y también presente, pero en menor densidad, en hueso que recubre la corona de las órganos dentarios, afectando a la función masticatoria. Es translucido de color blanco o gris azulado. La actividad iónica en Equilibrio (cuando no se reforma ni se redisuelve Hidroxiapatita) es una constante resultado de las concentraciones de Calcio, Fosfato y OH que se representa en el Kps (producto de solubilidad). En la condición de neutralidad, las especies iónicas predominantes en la solución son los fosfatos primarios y secundarios. NOW Calcium Hydroxyapatite is derived from Australian, certified BSE-free, young pasture-fed cattle. It is a highly absorbable source of Microcrystalline Hydroxyapatite (MCH), which includes calcium, phosphorus, magnesium, protein, minerals and amino acids normally found in bone tissue. As mentioned earlier, HA is a member of the apatite family (consists of Ca and phosphates) with the general formula Ca 5 (PO 4) 3 OH, and unit cell formula Ca 10 (PO 4) 6 (OH) 2. In the unit cell of HA, Ca and phosphates are arranged in such a manner that four Ca atoms are surrounded by nine O atoms of the phosphate moieties at the M1 position ...
