Abstract

1. Process for the production of the cosmochlorine compound having the composition NaCrSi2 O6 , characterized in that, based on the formula NaCrSi2 O6 , stoichiometric to substantially stoichiometric quantities of components, which, in the composition thereof, give the overall composition NaCrSi2 O6 , optionally only after heating to the reaction temperature, are mixed, if appropriate with the addition of mineralisers, and heated at least twice to a reaction temperature between 850 and 1150 degrees C with intermediate sizereduction.
