Abstract

Procedure for the production of a refractory mass, especially for coating at least partially containers for vacuum degassing, consisting essentially of a granular material of magnesia and chromite with a chemical binder, characterized in that a sintered grain of magnesia is mixed and Chromite previously reacted and calcined at high temperature with a Cr2O3 content of 10 to 30% by weight, a content of MgO above 42% by weight, each containing SiO2 and CaO of not more than 3% by weight, and a proportion from lime to silicic acid greater than 1, the chromite components being present in the fundamental mass of magnesia practically totally in the form of spinel deposits and the residual components of the original chromite grains being presented only in a maximum amount of 10 % by volume, with a phosphate soluble in water in an amount of 1 to 5% by weight as a chemical binder.
