Beschreibung
Zusammenfassung:	THIS INVENTION RELATES TO A SIMPLE AND RELIABLE OF PROCESS OF PRODUCING HIGHLY CRYSTALLINE HYDROXYYAPATITE POWER WITH SUPERIOR PROPERTIES ACHIEVABLE AT RELATIVELY LOW SINTERING TEMPERATURES. THIS COMPOSITION IS FORMED UNDER AMBIENT CONDITIONS, BY REACTING CALCIUM HYDROXIDE WITH PHOSPHORIC ACID IN THE MOLAR RATIO OF 1.67 . SIMPLE, BUT EFFECTIVE PROCESSING CONDITIONS ARE EMPLOYED TO OBTAIN HIGHLY DENSE HYDROXYAPATITE CERAMIC BODY SUITABLE FOR BIOMEDICAL APPLICATIONS.
