Abstract
Electrical resistance of hydroxyapatites in an interval from room temperature to 1200 °C have been studied. It is shown that the resistance of hydroxyapatite depends sufficiently from the impurities. To identify the impurities, XRD, IR, MS measurements were carried out. It was established that the electrical resistance of hydroxyapatite is related to the water content in the samples, nitrous substances and carbonate ions located inside of hydroxyapatite crystal lattice. Energy activation of electrical conductivity in hydroxyapatite is calculated.
