At the same time, we can demonstrate ways of partially reducing the organic pigment content in a filament formulation by means of iron oxides
, when the application calls for better weather stability.

"We plan to be producing significantly higher volumes of our ultramarine blues and micronized iron oxides
by early 2019 through this expansion project in Colombia.
The most striking feature of the iron sandstone layer at Kasangulu is the occurrence of iron oxides
along subparallel cracks within the quartz grains (Fig.
The newly developed Ningbo Process is based on patented technology, he adds, and ensures the most environmentally-sound production of synthetic yellow-shade red iron oxides
* Charles Hoover, president of Hoover Color Corporation, explains the benefits and limitations of iron oxides
. New trends in the powder coatings industry have recently caught his attention.
As reported by Sherman and Waite , species based on iron oxides
and hydroxides have four predominant regions of absorption: ligand to metal charge transfer (250-400 nm) along with contribution of [Fe.sup.3+] ligand field transition (290-310 nm), pair excitation process (400-600 nm) of magnetically coupled [Fe.sup.3+] ions, and two strong absorption bands near 640 and 900 nm of ligand field transitions of [Fe.sup.3+] cation in the octahedral environment.
There are sixteen iron oxides
, oxide hydroxides, and hydroxides known in the environment to date.
Historically, iron oxides
have been the additives of choice, primarily red iron oxide
(hematite, [Fe.sub.2][O.sub.3]) and black iron oxide
