This producer did not maintain separate data 15/ on production of this crude form
of tungstic acid. ~ The tungstic acid imported from the PRC was of a substantially
more 16/ refined form than that which was produced in the UnTted States.

TUNGSTIC. ACID. PART XCII. THIS acid does not exist in nature in an uncom-
bined state, but always united to lime ( tungstate of lime J or with iron and
manganese (wolfram). PROPERTIES OF TUNGSTIC ACID. Tungstic acid
appears in a ...

The elements of experimental chemistry
This oxide, when heated in an open crucible, burns vividly, and is changed into a
yellow powder, which is tungstic acid. Tungstic acid may be reduced to a metallic
state, by heating it intensely with charcoal in the usual manner; but the process ...

This product is more pure than the above, because of the higher purity of APT. PP
: Amorphous, yellow powder. CP: Nearly insoluble in water or acid solutions, but
freshly prepared tungstic acid forms colloidal solutions when treated with water.

When the reduction is attempted in a porcelain crucible, a loss is always
experienced, arising from the oxygen of the stannic acid, which is reduced to
metal, and a third of the oxygen of the tungstic acid, which changes to tungstic
oxide.
Sir William Crookes, 1864

Tungsten is always obtained in the form of a black powder, having a density of i7-
i to 1 7^3 for the metal reduced with carbon, and i7'o to 18-2 for tho metal
reduced by hydrogen. Upon fusing turnings of gray cast iron with tungstic acid or
white ...

Upon fusing turnings of gray cast iron with tungstic acid or white cast iron with the
addition of carbon,, the author obtained alloys possessing remarkablo properties
and especially of great hardness. He admits that the carbon present in cast iron ...

oxide.
WILLIAM CROOKES F.R.S, 1864
He admits that the carbon present in cast iron in the state of combination does not
act upon tungstic acid, and that only the carbon in the state of mixture reduces the
tungsten to the metallic state. Indeed, the alloys obtained still contain carbon, ...
