ABSTRACT:
To produce a dolomite sinter with a low porosity and a good hydration stability made of difficult-to-sinter raw dolomite, the dolomite is milled and caustic burnt dolomite, dolomite hydrate or semi-burnt dolomite in quantities between 3 and 20% by weight relative to the total mixture is added to the raw dolomite powder and is calculated as oxide, as well as foreign oxide, such as Fe.sub.2 O.sub.3, Al.sub.2 O.sub.3 or SiO.sub.2, in such quantities that the total content of the foreign oxide mixture is 1 to 3% by weight.
