early in 2016, LANXeSS Inorganic Pigments will
launch the New Red range of iron oxides manufactured using a comprehensively improved Penniman production process. the new, purpose built, manufacturing plant for New Red is located in Ningbo, china, in
the Ningbo Petrochemical economic & technological
development Zone (NPedZ), one of the largest and
most modern chemical parks in the world. the focus
of this new facility will be the manufacture of highly
saturated, bright, yellow-shade reds.
by-products. For example, process optimization will lead
to a significant reduction of generated carbon dioxide
equivalents. Remaining residues will be processed in a
nitric acid recovery plant and be re-used as raw material.
The traditional Penniman Red process leads to the generation and emission of laughing gas. Since nitrous oxide
cannot be converted to nitric acid, an additional treatment is necessary. A special catalyst will be employed to
convert the laughing gas to naturally occurring nitrogen
gas, oxygen and water.
Our very innovative process will not only produce high
quality pigments with unique color properties, it will be

The plant is designed for the production of 25,000 metric
tons of red iron oxide per year. In addition, a mixing and
milling operation will bring the total capacity in Ningbo to
approximately 70,000 metric tons per annum.

of New Red
Iron oxide red pigments are produced globally by different production processes. the Laux and copperas processes use high temperatures in oxidizing conditions to convert source materials to the desired
red shade. In the Penniman Red process, a well-defined hematite seed is grown in the presence of steel,
ferrous nitrate and air.
Due to the inherent chemical
structure of red iron oxide and
challenges in production, the
range of shades which can be
achieved which offer both high
red values (a*) and high yellow
values (b*) has traditionally
been limited. New Red will
utilize innovative process developments and control combined with careful raw material
selection to produce the reddest iron oxide red pigments.

the extraordinary color development of New Reds
is indicated by examining the pure pigment powder.
An example of New Red pigment made using the
upgraded Penniman process is shown on the left
hand side above. the right side shows a typical
bright yellow-shade red.
New Red pigments will be subjected to intensive milling to ensure that they contain a low amount of aggregates and can
therefore be easily processed by our customers. The viscosity course of coating formulations containing high loadings
of New Red are approximately Newtonian in behavior. This
enables greater versatility during production. Furthermore
the pigments show good color stability even when using
bead mills.
