silicon agglomerates with the iron formed by the reaction between silicon and iron oxide. Thus the presence of globular iron-silicon droplets in breakout slag samples (obtained during the period of low flat temperature 10 minutes after casting begins), provides direct evidence for the persistence of startup powder in the mold.

Some tests unique to powders may also be used. For example, an iron powder may have an unknown percent of iron oxide, (Fe 2 O 3). A test sample of the iron powder is taken and exposed to a stream of hydrogen. Weight loss that occurs in the sample is measured. From this, the percentage of iron oxide present in the powder can be calculated.

A process for the production of nodular cast iron is disclosed. The process comprises adding magnesium to molten iron and then desulphurizing the melt. Next, the melt is after-treated with a neutral gas. The neutral gas which is introduced into the melt may be Ar, N 2 , CO 2 , or any combination thereof.

Thus for MIM, the chief concern is to have a very fine powder to promote high sintering activity. Typical specifications call for a median size of ~10 microns with a D90 of 20–30 microns. UHPWA can provide such a powder with a yield of 70–80% from the atomised powder. Gas atomisation struggles to provide more than a 50% yield.
