| Abstract: | High-precision, computer-refined values of the cell parameters of calcium hydroxyapatite, Ca10(PO4)6(OH)2, have been determined with an X-ray diffractometer, internally standardized by means of sodium chloride. The results obtained are as follows: a
0=9.4192 Å c
0/a
0=0.731 c
0=6.8867 Å volume=529.2 Å3
The apatite work was supported by a research grant DE-02105 from the United States Department of Health, Education, and Welfare. I am very grateful to Dr. W. R. Liebenberg, Dr. S. A. Hiemstra and Dr. H. V. R. von Rahden of National Institute for Metallurgy, South Africa for their valuable help and interest and Prof. Nelson Fuson and Prof. James R. Lawson for advice and discussion. |
