Paper Title:
In-Situ Templating Synthesis of Thermally Stable Hydroxyapatite with Ordered Nanostructures
  Abstract

Alkyl phosphates, the products from the reaction between phosphorous pentoxide and various alcohols, were used as the in-situ templates of nanostructure as well as phosphorus source of HAP. The obtained precursor samples had ordered nanostructures:lamellar structure for dodecyl and n-octyl phospahes templated samples, cubic for n-pentyl and hexagonal for ethyl phosphates templated samples. The calcined ethyl phosphate templated sample was pure HAP with a specific surface area of 42m2/g, and sustained with an orderly hexagonal nanostructure at 400°C. But the calcination at 400°C caused the collapse of other alkyl phosphates templated nanostructures.
