Abstract
Accurately known values of material properties for single crystals of silicon are necessary, to apply corrections in a planned high precision determination of Avogadro´s constant. Measurements of the coefficient of thermal expansion and of the compressibility of silicon are performed by interferometry in the range from vacuum to atmospheric pressure and from 15/spl deg/C to 25/spl deg/C.
