Definition of Fe2O3
Fe2O3Multiple Mul"ti*ple, a. [Cf. F. multiple, and E. quadruple,
Containing more than once, or more than one; consisting of
more than one; manifold; repeated many times; having several,
or many, parts.
Law of multiple proportion (Chem.), the generalization that
when the same elements unite in more than one proportion,
forming two or more different compounds, the higher
proportions of the elements in such compounds are simple
multiplies of the lowest proportion, or the proportions
are connected by some simple common factor; thus, iron and
oxygen unite in the proportions FeO, Fe2O3, Fe3O4,
in which compounds, considering the oxygen, 3 and 4 are
simple multiplies of 1. Called also the Law of Dalton,
from its discoverer.
Multiple algebra, a branch of advanced mathematics that
treats of operations upon units compounded of two or more
Multiple conjugation (Biol.), a coalescence of many cells
(as where an indefinite number of am[oe]boid cells flow
together into a single mass) from which conjugation proper
and even fertilization may have been evolved.
Multiple fruits. (Bot.) See Collective fruit, under
Multiple star (Astron.), several stars in close proximity,
which appear to form a single system. Fe2O3Bower-Barff process Bow"er-Barff" proc`ess . (Metal.)
A certain process for producing upon articles of iron or
steel an adherent coating of the magnetic oxide of iron
(which is not liable to corrosion by air, moisture, or
ordinary acids). This is accomplished by producing, by
oxidation at about 1600[deg] F. in a closed space, a coating
containing more or less of the ferric oxide (Fe2O3) and the
subsequent change of this in a reduced atmosphere to the
magnetic oxide (Fe2O4). Fe2O3Ferric Fer"ric, a. [L. ferrum iron: cf. F. ferrique. See
Pertaining to, derived from, or containing iron. Specifically
(Chem.), denoting those compounds in which iron has a higher
valence than in the ferrous compounds; as, ferric oxide;
Ferric acid (Chem.), an acid, H2FeO4, which is not known
in the free state, but forms definite salts, analogous to
the chromates and sulphates.
Ferric oxide (Chem.), sesquioxide of iron, Fe2O3;
hematite. See Hematite.
