Nanostructured bioactive mateials prepared by spray drying techniques

摘要

Nano-particles of calcium and phosphorous compounds are made in a highly pure generally amorphous state by spray drying a weak acid solution of said compound and evaporating the liquid from the atomized spray in a heated column followed by collection of the precipitated particles. Hydroxy apetite (HA) particles formed by such apparatus and methods are examples of particle manufacture useful in bone and dental therapies.
