METALLIC-CERAMIC AND INTERMETALLIC COMPOUNDS BY THE FLOATING ZONE TECHNIQUE.

Abstract

The use of the floating zone process for the preparation of refractory materials is discussed. This process has been used to prepare columbium-aluminum oxide cermets and the intermetallic compound nickel aluminide (NiAl). Small amounts of aluminum oxide harden columbium and higher concentrations of aluminum oxide form a series of metallic and non-metallic phases. Zone melting a nickel tube with an aluminum rod inside it has resulted in a small amount of what appears to be NiAl. (Author)
