Chemical Knowledge and Market Trends on Iron Oxides

What are Iron Oxides

Iron oxides are chemical compounds composed of iron and oxygen. There are sixteen known iron oxides and oxyhydroxides, the best known of which is rust, a form of iron oxide. Iron oxides is widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin.

Chemical Weathering of Iron Oxides

There are two main types of chemical weathering - dissolution & oxidation which both depend on what substance the rock component consists of. Dissolution occurs when minerals containing elements that can easily be dissolved by rainwater are exposed to it for long periods; Oxidation occurs when water reacts with components containing oxygen; examples include iron oxides (Hematite) & Hydroxide Ions (rust), which oxidized from iron oxides to hydroxide Ions, aluminum & Iron, which oxidize to form aluminium oxides (Kaolin),By doing this, what was once rocks were turned into soil and sand.

Iron Oxides Uses

◇ Iron Oxides in cosmetics: as a pigment

Pigments are also called colorants or colorants, that is, the sum of substances that can be used to change the color of other substances or products. The role of adding various pigments in cosmetics is to make cosmetics beautify and modify. Pigments can be divided into three categories: synthetic pigments, inorganic pigments, and natural plant and animal pigments according to their sources. Inorganic pigments are called mineral pigments. White pigments used in cosmetics, such as talc, zinc white, titanium dioxide, etc .; colored pigments, such as iron oxide, carbon black, oxidized chlorine, etc. 

◇ Iron Oxides: a notable minerals

Iron oxide is a chemical material, and also a very important mineral. Why? Perhaps you've heard of bauxite as a compound used in aluminum production. But did you know that bauxite is actually a mixture of minerals? That said, these natural elements are mixed with clay and oxygen to form an ore. The main element in bauxite is aluminum hydroxide; other notable minerals include iron oxide, silicon dioxide, titanium dioxide and magnesium hydroxide

◇ Use in the synthesis of hydrazine

Sodium ethoxide is used as a catalyst for the synthesis of hydrazine in catalysis by means of dehydrogenation reaction by heating it with metallic iron or iron oxide to yield hydrazinium ion and nitrogen oxides such as nitric oxide at high temperature and pressure.

Industry News and Market Trends

● Hoover Color introduced a new class of transparent iron oxides

Hoover Color, a division of the CATHAY INDUSTRIES Group, introduced a new class of transparent iron oxides. Being the result of an environmental restoration effort which involves recovering iron oxide from abandoned mine drainage, the Environ Oxide products are the world’s first iron oxide pigments produced with such unique manufacturing process. Just like their conventional counterpart, these pigments have high purity and quality, show excellent performance and are even easier to disperse.

● LANXESS expanded its Colortherm Yellow pigment series

LANXESS has expanded its Colortherm Yellow pigment series for heat-resistant high-performance plastics. Two new inorganic yellow pigments are now on the market, namely Colortherm Yellow 5 and Colortherm Yellow 26. They are based on iron oxide and zinc oxide, respectively, and are specially designed for low-cost coloring in the temperature range of 220°C to 260°C. In the same color space, they have the same high color intensity, providing plastic manufacturers and processors with an excellent compromise between the best-in-class Colortherm Yellow 20 and Colortherm Yellow 30 products. These products are thermally stable. The performance is as high as 300°C.

● Suppliers announce to adjust price of Irion Oxides

Deqing Totian Sanfeng Pigment: From May 1st, the price of all iron oxides will be increased by 500 CNY/ton on the basis of the original sales price.
