Using a hydrodynamic model of protogalactic evolution, the amount of iron in rich clusters is explained, deduced from X-ray observations. Calculations show that a strong shock wave originates in the first violent collapse phase and leaves the protogalaxy, carrying out a substantial fraction of its mass, with roughly solar metallicity and high temperature. It is also shown that hot material ejected from proto-cD galaxies can probably explain the observed X-ray emission in clusters.
