Powder Metallurgy discusses the production of metal powders and other materials made from it. It defines the meaning of metal powders with some illustrations. The book also identifies the processes similar between the production of metal powder and ceramic products. The technology involved and the variation in the process of metallurgy are covered in some chapters of the book. The book enumerates certain advantages in using powder metallurgy over other processes. Methods such as the reduction of the oxides of metals, electrolysis, thermal dissociation, and chemical disintegration are explained. The origin and improvement made on the method are discussed in detail. The goods created using the process are also explained, as well as the types of metals that are being used. A chapter of the book focuses on the flaws of powder metallurgy. The book will provide useful information to metal smiths, chemists, students, and researchers in the field of chemistry.

As part of the Bureau's research into developing methanation catalysts for converting synthesis gas derived from coal to synthetic natural gas, this report describes a method to prepare supported Raney nickel coatings by dipping screen-covered nickel sheet in molten aluminum-nickel alloy.

Five years ago, the worldwide powder metallurgy fraternity gathered in New York City to attend the first international conference devoted entirely to powder metal lurgy to take place in the United States. It was a tentative venture, entered into by the sponsors with no idea as to whether it would fail or succeed. The only assurances we had were that the metal-powder producing and consuming industries were rapidly expanding and that powder metallurgy was truly becoming one of the international sciences. The 1960 Conference was successful not only in terms of attendance and interest, but also in terms of knowledge gained. The literature had been enriched by the contributions of its participants to foster and encourage this type of world wide exchange. Thus, another such conference was held in 1965-expanded in scope and supplemented by an exhibition of the latest advances in raw materials, processing equipment, and finished products of powder metallurgy. On behalf of the Conference sponsors-the Metal Powder Industries Federa tion, the American Powder Metallurgy Institute, and the Metallurgical Society of AIME-I thank all those who participated and who helped make the 1965 Interna tional Powder Metallurgy Conference a rewarding experience and memorable event in our industry's history. Support of the National Science Foundation, which made it possible for several speakers from abroad to participate in the program, is gratefully acknowledged.
