Iron oxide pigment for ceramics is a commonly used coloring agent in the ceramics industry that imparts a range of hues ranging from yellow to red-brown to black in the final product. It is made by grinding iron oxide raw materials into fine powders that have a specific particle size distribution. Iron oxide pigments have been used since the ancient time, and their use is still prevalent in modern-day ceramics.
Iron oxide pigments have a wide range of applications in ceramics, such as coloring brick, tiles, and pottery. They are used as natural raw materials that are easy to source, cheap, and very stable. Iron oxide pigments are environmentally friendly, as they are non-toxic and do not emit harmful substances during the firing process, making them safe to use in both the production and disposal stages.
The expertise required in the production of iron oxide pigments for ceramics involves a keen understanding of the properties of the raw materials used and the production process stages. The raw materials used include hematite, magnetite, and goethite, which are refined through crushing, milling, and sieving to obtain the powder. The powder is then heated to high temperatures to produce the final product.
The experience required in the use of iron oxide pigments for ceramics involves an understanding of the color characteristics imparted by different types and amounts of iron oxide pigments. The hue of the final product depends on the type of iron oxide pigment used, the amount added, and the firing temperature. Trial and error may be required to achieve the desired color, and an experienced ceramic artist will know how to adjust each of these variables appropriately.
Lastly, the authoritativeness of iron oxide pigments for ceramics arises from their extensive use and the multiple benefits they offer. Their stable chemical composition, environmental friendliness, and ease of use make them a popular choice in the ceramics industry. Iron oxide pigments have also been proven to have excellent rust, weather, and UV resistance, making them a long-lasting solution for coloring ceramics.
Overall, iron oxide pigments for ceramics remain a critical part of the ceramics industry, providing a range of hues while being cheap, easy to source, and environmentally friendly. Their use requires expertise in production and experience in application, but their multiple benefits and long-lasting durability make them an excellent choice for anyone looking to color their ceramics.
Iron oxide pigments are extremely light stable and can therefore be exposed to outdoor environments for long periods of time without noticeable color fading.
Because iron oxide pigments are available in a variety of oxidation states, a wide range of colors can be achieved through different formulations and treatments, from bright to deep.
Iron oxide pigments are widely used in coatings, paints, plastics, rubber, ceramics, asphalt, cement and other fields to provide color stability and uniform tinting effect.
Iron oxide pigments have excellent weathering resistance, with high resistance to light, chemicals and climate change, and are not easily faded or discolored.
Compared to some other pigments, iron oxide pigments are often considered an environmentally friendly choice as they contain no heavy metals or other harmful substances.
Iron oxide pigments maintain color stability during the preparation process and do not change color when exposed to heat or light.
Iron oxide pigments remain stable at high temperatures and are therefore often used in products that are resistant to high temperatures, such as ceramics or refractory materials.
Iron oxide pigments are mainly composed of iron and oxygen elements. Depending on the oxidation state, they can be formed into a variety of colors, such as red, yellow, brown and black.
Iron oxide pigments are widely adopted for their stability, weather resistance and versatility, and their relatively low cost makes them a cost-effective choice for making a wide range of color products.
Iron oxide pigments have excellent covering ability, which can effectively hide the color or imperfections of the underlying layer when covering the surface.
