Temperature resistance, i.e. a combination of melting point and oxidation resistance, may be of prime importance. A general correlation exists between melting point and hardness since both reflect the bond strength of the atoms in the crystal lattice, and the preferred order of coating metals for use in high temperature applications as temperature is increased is silver, aluminium, nickel, rhenium, chromium, palladium, platinum and rhodium. 

Electroless nickel deposition may then be carried out directly onto steel, aluminium, nickel or cobalt surfaces. Surfaces of copper, brass, bronze, chromium or titanium are not catalytic for deposition of nickel-phosphorus and the reaction must be initiated by one of the following operations ...

Heat conductivity of hydride powders is insignificant, 0.3-lW/(m-K). For improvement of effective heat conductivity of a hydride reactor stuffing in it enter a skeleton from a high-temperature material (copper, aluminium, nickel). The design of such skeleton can be variously. For example, it can be as radial disks (a plate reactor), as a goffered insert (from the punched foil or a grid), the grids braided in a spiral, cellular bodies. 

A convenient method to produce powdered skeletal catalysts is to use the procedure described by Freel and co-workers [16] for Raney nickel. The same relative proportions of alloy and leachant can be used to maintain the leach reaction relatively isothermal when larger quantities of catalyst are desired. In their method an aqueous solution containing 40wt% NaOH is added stepwise to 30 g of alloy powder and 150 ml of distilled water in a vessel at 313 K. Alkali additions arc made at approximately 2-min intervals. For the first 20-min period the volume of alkali added is 2 ml, and 5-ml additions are made thereafter. A reaction time of around 3 h is sufficient to fully leach 500-jim particles of aluminium-nickel or aluminium-copper alloys at 313 K. After extraction the catalysts are washed with distilled water at ambient temperature, first by decantation and then by water flow in a vessel until the pH is lowered to around 9. The samples can then be stored in...

A special type of catalyst which is typified by Raney Nickel is prepared by leaching out one component from a binary alloy leaving a skeletal structure of the desired catalyst. Raney Nickel itself is made by leaching out aluminium from an aluminium-nickel alloy with sodium hydroxide. Cobalt and iron catalysts have also been prepared in this manner.
