Title:
金属塩ナノ粒子、特にナノ粒子を有するカルシウムとホスフェートのフレーム合成
Document Type and Number:
Japanese Patent JP4988548
Kind Code:
B2
Abstract:
Described is a method for the production of metal salts, wherein the cationic metal is preferably selected from Group I to IV metals and mixtures thereof and the anionic group is selected from phosphates, silicates, sulfates, carbonates, hydroxides, fluorides and mixtures thereof, and wherein said method comprises forming a mixture of at least one metal source that is a metal carboxylate with a mean carbon value per carboxylate group of at least 3 and at least one anion source into droplets and oxiding said droplets in a high temperature environment, preferably a flame. This method is especially suited for the production of calcium phosphate biomaterials such as hydroxyapatite (HAp,Ca10(PO4)6(OH)2) and tricalcium phosphate (TCP,Ca3(PO4)2) that exhibit excellent biocompatibility and osteoconductivity and therefore are widely used for reparation of bony or periodontal defects, coating of metallic implants and bone space fillers.
