Abstract

The uniaxial stress component(USC)in NaCi samples compressed in a tungsten carbide opposed anvil hgh-pressure x-ray apparatus has been determined to 10GPa by a method proposed earlier by sing and Kennedy.In the pressure range 1-10GPa,the pressure dependence of the lower estimates of USC can be expressed by the relation r(P)=0.24(=0.04)+0.11(=0.005)p, where r(p) is the USC at a pressure p,r(p) and p being expressed in the units of giga pascals (GPa).These results have been used to estimate the difference,ap, between the pressures calculated from the hydrostatic component of strain and the strain averaged for the first six strong reflections of NaCi.Ap is found to increase linearly from -0.1GPa at 1GPa to -0.4GPa at 10 Gpa.
