Iron Oxide Red Powder

Iron Oxide Red Powder has good coloring property, strong covering property, high color concentration, light resistance, high temperature resistance and impermeability.

It is suitable for coloring various building structures and cement components, as well as various paints and coatings, including water-borne coatings, powder coatings and plastic coatings.

Iron Oxide Red Powder is a naturally occurring ore of iron, and is often sold as red iron oxide.

Primarily used as a source of iron, red iron oxide has many other uses.

Iron Oxide Red Powder is used as a pigment/dye/colourant for many materials including ceramics, glasses, glazes and even food.

Its resistance to heat and antipruritic properties mean that it is often used for casings and coverings.

Additionally, red iron oxide is used as a flux in ceramic and glaze production.

Iron Oxide Red Powder, most commonly known as rust, is a chemical compound of iron and oxygen.

In the industrial realm it is known as red iron oxide and is one of the most important minerals.

This compound of iron and oxygen is only one of sixteen known oxyhydroxide variants.

As a granulated powder it makes an excellent cost effective colourant.

Red iron oxide is one of the oldest pigments to be used by every major civilization.

Naturally occurring as deposits in crystalline form, variations of haemetite can be found around the world.

Even far away on Mars, red iron oxide is available naturally.

On Earth, it coexists with several other minerals including chalk, clay, and quartz.

Readily available in several forms, only two forms are specifically used as a colourant and can be used in the production of industrial, commercial, and household products including: Colourant, Pigment, and Dyes

The company Hebei ChaoKe has a large global footprint with over 170 million coloured bricks produced every year.

Qualities as a colourant include permanency and dependability with extensive opacity and tinting strength.

Additionally, haemetite is indifferent to alkalis, does not react with solvents, but are partially soluble in acids.

Clay and Ceramic Colouring

Classical terracotta colourations will be observed in most clays post firing, to which 4 to 10% by weight Iron Oxide Red Powder has been added.

Alongside other pigments, the use of red iron oxide as the primary pigment can lead to a wealth of other colours and hues.

When used at 65% weight, iron oxide alongside kaolin and sand will afford a vividly read pigment in porcelain; deep black ceramics can be produced when 10% of the hematite is replaced with powdered magnesite ore.

Coral pink can be observed when the same amount of hematite/red iron oxide is replaced with zirconium silicate.

Modulation of the characteristic red-brown chromophore resulting from red iron oxide by the addition of other metals will result in a wide bouquet of possibilities in terms of colour.

Glass

The red colouring provides UV protection, and provides non leeching containment which is important to products like beer, wine, pharmaceuticals, and oils, and for plate glass for residential, commercial, automotive, and architectural use.

In general, the darker the bottle colour, the better resistance to ultraviolet light, and thus the better the chance of preservation of the container glass’s contents.

Glazes

A logical extension from ceramic pigments to glazes is natural with hematite/red iron oxide.

When combined with silica, 10% by weight of Iron Oxide Red Powder is more than sufficient to produce a lustrous red glaze after firing in excess of 1000 °C - with the hematite-silica combination glaze pigment possessing enhanced levels of stability over pure hematite or silica.

This reduced temperature requirement is well suited to the modern ceramic industry, which relies on fast turnarounds and maximal use of equipment.

On the other hand, hematite glazes can be fired to produce blueish colourations in reducing environments, with the addition of oxides of potassium being responsible for a modulation of the blue towards green.

Crazing is reduced by the addition of red iron oxide/hematite in the glaze prior to firing in quantities exceeding 2% weight.

Such quantities may not afford colouration.

Crazing is where small, hairline cracks form in a glaze due to thermal expansion of the glaze over time, even after firing.
