The improve of well-being and longevity of the population in Europe results in an increasing demand for the development of biocompatible materials with new properties which can be applied as implants for several decades. The one of most used biomaterial worldwide is a hydroxyapatite (HAP). This chemically similar material to the mineral component of bone and hard tissues is one of the bioactive materials, which can react with the tissue and generates good chemical bonding. The different preparation routes of HAP are known. In this study, the environmental friendly and cheap process from natural resources is shown. The examination of biogenic HAP confirmed the submicron sized structure with ~ 100 – 150 nm globular grains. The measurements confirmed the high structural stability of HAP grains.
