FIELD: medicine.
SUBSTANCE: present invention concerns the particles useful in x-ray visualisation, containing a kernel from a metal element of tungsten, probably, together with other metal elements where the tungsten content in a particle kernel makes from 20 to 100 wt % of metal tungsten and where the charged coat layer is applied on the specified kernel for passivation of a reactive surface of kernels of tungsten particles. The invention also concerns pharmaceutical preparations containing specified particles, a way of reception of the specified particles and their application as radiopaque substances.
EFFECT: development of a way of reception of the tungsten particles useful in x-ray visualisation.
