Precision Measurements of the Lattice Constants of Twelve Common Metals

TLDR: In this article, the lattice constant for aluminum, iron, nickel, copper, molybdenum, palladium, silver, tungsten, platinum, gold, lead and bismuth was determined within 1 percent (03 percent for W) for aluminum.

Abstract: The lattice constant $a$ has been determined within 01 percent (03 percent for W) for aluminum, iron, nickel, copper, molybdenum, palladium, silver, tungsten, platinum, gold, lead and bismuth, by direct comparison with NaCl, $a(\mathrm{NaCl})=2814$A As pure samples as could be obtained were used, from 9955 percent for Ni to 999995 percent for tungsten, and in many cases commercially pure samples were also measured for comparison The results for the purest samples are summarized in Table XIII The density from the x-ray data is in each case (except Al and Ag) greater than the density of the bulk metal as given in the literature, the difference being rather large for Mo (1021 vs 91), for Pd (1225 vs 119) and W (1932 vs 1877) For pure W remarkably sharp lines were obtained For Bi a piece of a single artificial crystal was used
