Abstract
A low crystallinity calcium phosphate powder is prepared by mechanically grinding a calcium phosphate solid under grinding forces local heating sufficient to mechanically alloy the calcium phosphate solid and reduce the crystalline domains of the calcium phosphate solid to less than about 100 nm. The method is useful for making any calcium phosphate material by solid-solid mixing and high energy grinding.
