摘要： A process for selectively forming a morphology of reduced material is disclosed. The reduced material, such as titanium, is formed by a process of electrochemically reducing a metal oxide feed material, such as titania, in a solid state in an electrolytic cell containing molten chlorine-containing electrolyte in the cell. The process for selectively forming the morphology of reduced material includes sintering the reduced material and forming a morphology that is susceptible to subsequent washing of retained electrolyte in the reduced material.

摘要： A precursor powder comprising a metal compound is formed into a sample for electro-deoxidation, for example by slip-casting. The sample is then immersed in a melt comprising a molten salt and a cathodic potential applied to remove non-metal species from the precursor powder by electro-deoxidation and dissolution in the melt. This typically forms a metallic sample which can be fragmented to form a metallic powder. In a second aspect of the invention a powdered feed material is formed into a shaped precursor and more extensive electro-deoxidation carried out so as to form a near-net shaped product.

摘要： A noble metal nanoparticle can be grown on a semiconductor substrate by contacting a predetermined region of the substrate with a solution including noble metal ions. The predetermined region of the semiconductor substrate can be exposed by applying a polymeric layer over the substrate selectively removing a portion of the polymeric layer. The nanoparticles can be prepared in a predetermined pattern. The nanoparticle can be formed with a barrier separating it from another nanoparticle on the substrate; for example, nanoparticle can be located in a pit etched in the substrate. The size and location of the nanoparticle can be stable at elevated temperatures.
