These popular slurry grades are shipped at 60% solids content and deflocculated with sodium silicate to maintain stable rheology characteristics. All the above grades are suitable for a variety of ceramic casting formulations ranging from standards bench cast to pressure cast and capillary type production systems. High permeability with good strength and plasticity are key properties of these slurry grade clays.
