| Abstract: | A series of compounds with
composition of Ca1–xCuxHPO4,
where x varied from 0.05 to 0.5 were synthesized
by precipitation method. The compounds were characterized by elemental analysis,
X-ray diffraction, infrared spectroscopy, scanning electron microscopy, and
thermogravimetry. The chemical stabilities of solids were investigated at
several pH. Elemental analysis of copper, calcium and phosphorus are in agreement
with the proposed composition. The formation of lamellar phosphates was evidenced.
The stability of the set of compounds was better for samples with high copper
content. |
