摘要：

The lanthanum-containing oxyapatite, Ca10-xLax(PO4)6O1+ x 2□1- x 2, treated in a CO2 atmosphere at 950°C can be partially carbonated if x < 2; it remains uncarbonated when x = 2. The general formula of the carbonated apatites is Ca10-xLax(PO4)6Ox(CO3)1- x 2□1- x 2 O ≤ x ≤ 2. The number of La3+ and O2- ions on the one hand and the number of CO2- 3 ions and vacancies on the other hand are equal; each O2- ion is joined to a close La3+ ion, and each CO2- 3 ion is next to a vacancy. © 1990.
