DURANDAL RX – A superfine andalusite


durandalRXDurandal TM RX is a superfine andalusite material milled to a particle size close to primary crystallites to increase reactivity within refractory compositions and assist the mineralogical transformation to mullite.
Using this material with unique properties like anisotropic dilatometry, the matrix and not only the aggregates of a refractory composition can be enriched in mullite content at a lower firing temperature and thus provide the final product with better thermal shock resistance.
