Product Announcement from Washington Mills Electro Minerals Company

 Alumina Bubble...Duralum&#174; AB-Image

Washington Mills - Duralum® AB, alumina bubble, is an electric arc furnace product made from high purity Bayer process alumina and the product chemistry is similar to that of white aluminum oxide. Alumina bubbles are formed from molten alumina, resulting in hollow spheres of low bulk density.


Duralum®, bubble alumina, is used in the production of lightweight insulating refractories where low thermal conductivity, and high temperature properties are the prime requirements. Duralum® AB is also used effectively for loose-fill refractories.
