Sample

Processing steps
Step Chronology Date Type Process Changes
#1 before layer formation 1995-01-01 thermal melting of ferrous oxalate in an arc furnance under argon atmosphere changing composition to FeO
#2 before layer formation 1995-01-01 thermal quenching the melt quickly on water cooled copper plate formation of a melt droplet
#3 before layer formation 1995-01-01 mechanical embedding the melt droplet into epoxy resin
#4 during layer formation 1995-01-01 mechanical polishing of the embedded FeO melt droplet to obtain a smooth and flat surface
Comments
Argon atmosphere during melting was used to provide inert conditions and thus to suppress oxidation of divalent (ferrous) iron to trivalent (ferric) iron.
