In the present work, a simple sol–gel based method is reported for the synthesis of HA nanorods having a hexagonal crystal structure, using calcium nitrate, potassium dihydrogenphosphate and ammonia as chemical precursors. Rods of 70–90nm diameter and 400–500nm length, i.e. with an aspect ratio >5 are reported in this study.
