✦ Synopsis
We have investigated the e4ect of nickel on calcium phosphate formation from aqueous solutions. The calcium phosphates prepared under di4erent reaction conditions (pH, temperature, and nickel concentration) were characterized by X-ray di4raction, FTIR spectroscopy, and chemical analysis. The apatite compounds were also studied thermogravimetrically. From the combined results of the techniques employed we have determined that nickel favors the formation of brushite and amorphous calcium phosphate. We have found, as well, that the presence of nickel in the solution inhibits calcium hydroxyapatite (CaHAP) and octacalcium phosphate formation. However in the synthesis performed at basic pH and 953 3C the apatitic phase (HAP) could be obtained. The present results suggest that the presence of nickel may modify the precipitation of oral calcium phosphate. 2000
