FIELD: test engineering.
SUBSTANCE: method comprises determining period of crystal lattice by the Roentgen structural method and calculating the density from the formula presented. The period of the crystal lattice of complex monocrystals is determined by Roentgen method and, then, from the formula presented, the density of each chemical element that compose the complex monocrystal is determined in the unit cell of the crystalline structure, and, finally, the density of the complex material is determined as a sum of the densities of the components.
EFFECT: expanded functional capabilities and reduced labor consumption.
