AK 98 is a high purity natural caustic calcined magnesia product with controlled reactivity (low,medium, high and very high, i.e. SSA from 10m2 /g up to 100m2/g) and LOI. It is characterized by high whiteness, low SO3, low-acid insolubles, low heavy metals and low iron content. It is used for a variety of industrial/technical and special chemical applications such as production of magnesium compounds, catalysts and catalyst supports for the petrochemical industry and as polymer additive. AK 98 is also used in hydrometallurgy (precipitation process) as well as in the production of high quality fused magnesia (brick making grade), sintered or fused alumina-magnesia spinels and in high-tech ceramic formulations. Available in granular form or milled to meet customers’ requirements.
