Abstract

For a determination of the Avogadro constant N(A) by the x-ray crystal density (XRCD) method, the molar volume M/Rho of three different silicon crystals, NRLM1, NRLM2 and NRLM4, have been analysed systematically by measurements of their densities Rho and molar masses M. Details of the sample preparations and the measurement results are presented.
