The invention relates to a refractory ceramic mass comprising 60 to 99 MgO sinter and 1 and 40 wt.-% of a manganese containing spinel.

Refractory ceramic mass and use thereof

The present invention pertains to a refractory ceramic mass, consisting of 50 to 97 wt. % of sintered MgO as well as 3 to 50 wt. % of a spinel of the hercynite type.

Refractory ceramic mass and its use

The present invention pertains to a refractory ceramic mass, consisting of a pure magnesia component A and a component B, which consists of granules of pure magnesia, wherein the magnesia granules of component B have a ceating consisting of a refractory material whose granule size is fine compared with that of the magnesia granules and is chemically extensively inert with respect to the magnesia granule or reacts with the magnesia granule and/or itself consists of a plurality of components that are chemically reactive with one another.

The present invention pertains to a refractory brick based on at least one refractory metal oxide in a particle fraction of &lt;8 mm containing 4 to 30 wt. % of a very fine refractory fraction, prepared by firing below a temperature at which the particles of the very fine refractory fraction sinter by recrystallization with grain growth.
