Iron Oxide Pigments For Ceramic
Iron oxide red pigment is mainly introduced into ceramic pigment formula in the form of colorant. Such as brown series and black series in glaze pigment; zirconium iron oxide red pigment in zirconium series pigment; iron oxide red raw material is also widely used in black, coffee, brown series of billet pigment, as well as ceramic glazed tiles and other colorful cement bricks. Therefore, the dosage of iron oxide red pigment in ceramic pigment is very large, and the annual dosage is expected to be more than 10,000 tons. At present, the production methods of iron oxide red pigment used in ceramic pigment are mainly divided into sulfuric acid method and mixed acid method (nitric acid method). Take the thin iron plate as raw material, after processing, we get the red color bright iron oxide red pigment. Generally speaking, the comprehensive index of iron oxide red produced by nitric acid method is better than that of iron oxide red produced by sulfuric acid method.
1. What are the most common types of iron oxide red used in ceramics?
Iron oxide red 110, iron oxide red 130, iron oxide red 190 are the most popular, and iron oxide red 180, iron oxide red 120, iron oxide red 160, iron oxide red 140, iron oxide red 101 are also widely used in ceramics.
2ã??How much iron oxide red is used in ceramics?
The sales volume in China market is more than 10,000.00kg.
3ã??Which production process is better quality for iron oxide red applied in ceramics?
Currently, there are two production processes for synthesizing iron oxide red, sulfuric acid method and mixed acid method, which is also known as nitric acid method. The later ceramic quality is better than the first.
4, iron oxide red coloring ceramics what colors?
Iron oxide red used as a ceramic coloring agent, is the formation of ceramic glaze brown series, black series, cobalt iron series glaze, ceramic billet composition of black, coffee, dark brown and other colors of the pigment. The brown series occupies an important position in the ceramic industry. The crystal structure of the brown series is Fe-Cr-Zn-Al and Fe-Cr-Zn, Fe III is red, and the combination with chromium oxide green is golden yellow to black brown.
