1. A process for preparing a homogenous material, said process comprising the steps of:

  • connecting essentially spherical-shaped bodies at their points of contact to form a three-dimensional shaped body conglomerate;

    forming a three-dimensional framework by casting or injecting a generally incompressible liquid material different from the shaped bodies around said connected shaped bodies, the material of the framework being selected from a group consisting of polymers, ceramics and metals;

    compressing the three-dimensional framework together with the shaped bodies; and

    after at least partial hardening of the three-dimensional framework, removing the connected shaped bodies so that merely the polymer, ceramic or metallic three-dimensional framework remains in the form of the homogenous material.
