Abstract
The present invention is a process for first removing and isolating the calcium-phosphate crystals of bone from a substantial amount of the organic matrix and cellular constituents of bone without significant physical, chemical or structural alterations in the crystals. The crystals can then be further treated to remove the remaining amount of organic material associated with the crystals, leaving them essentially free of any of the organic constituents of bone, without significant physical, chemical or structural alterations in the crystals.
