      abstract = {A thermal method of making a hydrogen permeable  composition is disclosed. A mixture of metal oxide powder  and ceramic oxide powder and optionally a pore former is  formed and pressed to form an article. The article is dried  at elevated temperatures and then sintered in a reducing  atmosphere to provide a dense hydrogen permeable portion  near the surface of the sintered mixture. The dense  hydrogen permeable portion has a higher initial  concentration of metal than the remainder of the sintered  mixture and is present in the range of from about 20 to  about 80 percent by volume of the dense hydrogen permeable  portion.},
