Abstract
The compressibilities for different crystallographic directions in the orthorhombic modification of the ternary AgInS2 compound were studied as a function of pressure up to 4.5 GPa by the X-ray poweder diffract ion method under high pressure. The anisotropy of compressibility was found to exist and between the principial components of compressibilit y tensor the relation kappa(c) > kappa(a) > kappa(b) was observed. For the orthorhombic modification the bulk modulus is smaller than that f or tetragonal one.
