It is therefore simple in processing equipment and operation, effective in product quality control, and low in energy input, and produces less waste. In addition, powder metallurgy is also preferred to traditional melting and casting technologies to produce and process metal alloys containing metals of very different reactivities, densities and melting points. These advantages of powder metallurgy can only be realised on the basis of the low cost availability of the various metal and alloy powders.

8 V, the product contained small nickel metal particles distributed amongst the much larger perovskite crystallites. © Woodhead Publishing Limited, 2013 Forming metal powders by electrolysis 35 between these results are indicative of the process starting with the formation of Ni metal particles which then alloys with Ti from the slower reduction of TiO2. The FFC Cambridge process also works very well for making ternary alloy powders. 0 V in molten CaCl2 for about a day. The reduced pellet retained its body shape, but can be readily manually ground to a powder.

10) finds applications where: ∑ ∑ The finished product has a narrow size range. One product is desired in large volumes without specification changes. 1 Application to electronic solders Electronic solders are used to make the solder pastes that are used in an electronic device assembly on a very large scale (thousands of tons per year). 10 Centrifugal atomisation of steel at 70 kg min–1 to ~100 mm powder. g. Type III at 25–45 mm, Type IV at 20–38 mm. In the early days some producers used gas atomisation to make these products and found yields as low as 20%, as well as problems with oxygen pick-up and satellite formation.
