4.The remelted characteristics of a 410 mm diameter consumable electrode and the Mn distribution in various regions at the electrode tip during VAR process of alloy A-286 in a 506 mm diameter water cooled crucible were studied. It was found that the Mn evaporized mainly in the forming period of droplets at the electrode tip. The Mn distributed rather homogeneously in the liquid metal film.
7.Platinum, palladium and gold at 0.x×10-9 levels in geological samples are determined by minified fire assay-spectrographic method. The method consists of preconcentrating Pt, Pd, and Au from 10 g sample into 1 mg silver bead by minified fire assay and cupellation, and determining the contents with emission spectrometry by aroing the bead in a graphite electrode along with 9 mg osmium-antimony alloy (ω(Os) = 0.06).
