Making Amorphous and Crystalline Alloys by Solid State Interdiffusion
This method is a new synthetic approach in which thin (15-50 A) amorphous elemental layers are sequentially deposited to create a unique initial reactant. The approach overcomes the limitations of traditional, diffusion-limited, solid-state synthetic methods, which offer no control of the reaction pathway and therefore no control over which i...

Thermodynamically Metastable Skutterudite Crystalline-Structured Compounds
Inventors have discovered a way to prepare numerous skutterudite compounds which cannot be readily prepared using conventional solid state chemistry synthesis. This invention avoids the limitations of conventional synthesis (chiefly high temperatures and slow diffusion rates) by using a multilayer precursor technique which allows the diffusio...
