Analytical Chemistry of Minerals
Potassium pyrosulphate K2S2O7 and sodium pyrosulphate Na2S2O7 are fluxes
used most widely. Their most active component is free anhydride which acquires
a high reaction capacity in the fusion stage. Fusion with pyrosulphates is chiefly ...

Chemical Methods of Rock Analysis
With most silicate rocks this assemblage is best decomposed by fusion with
anhydrous sodium carbonate, but if certain oxide minerals preponderate (
ilmenite or rutile, for example), then potassium pyrosulphate can be used.
Chromite ...
D. Hutchison, P G JEFFREY, 2012
Only in this way is the full amount of the silica in the alumina precipitate to be
recovered.6 Formerly it was customary to regard that remaining undissolved
when the pyrosulphate melt was taken up with water or dilute acid as the total
amount.

The analysis of silicate and carbonate rocks
Phosphorus can not be determined in the ignited oxides after these have been
fused with pyrosulphate (B. a, below), for the reason that the treatment volatilizes
some of it. Fuming of a phosphate with sulphuric acid also volatilizes P205.
William Francis Hillebrand, 1919

The analysis of silicate ad carbonate rocks
Only in this way is the full amount of the silica in the alumina precipitate to be
recovered.6 Formerly it was customary to regard that remaining undissolved
when the pyrosulphate melt was taken up with sound as applied to the bisulphate
, but is ...

Only in this way is the full amount of the silica in the alumina precipitate to be
recovered.6 Formerly it was customary to regard that remaining undissolved
when the pyrosulphate melt was taken up with water or dilute acid as the total
amount.

Aspects of Ancient Indian Technology
The mixed oxides were dissolved by fusing them (in a platinum or silica crucible)
with A.R. sodium pyrosulphate and dissolved with the help of acidified (with
H2SO4) distilled water* and made up in a graduated flask.f Iron was determined
by ...

Results of Spirit Leveling in Illinois, 1896-1908, Inclusive
The weighed residue remaining after expulsion of this silica by hydrofluoric acid
is dissolved (except the platinum it may have held) by a little pyrosulphate ami
the cooled melt redissoh'ed in dilute sulphuric acid. Any barium will then be left in

1 — 13 m2 g-1. It is now apparent that the catalyst exists under reaction
conditions as a potassium pyrosulphate melt containing vanadium oxides,
distributed in the pores of an inert support material. The evidence for a molten
catalyst phase is ...
