 Washed kaolins AL, CL and SOKALITE provides a source of alumina which combined with the silica in the body components form mullite which gives fired strength to refractories.

 Low fluorine in a kaolin, helps to protect the environment. The SOKA kaolins are known to contain some of the lowest levels of fluorine.

 High refractoriness.
