FULLN GLAZE ceramic glaze pigment coral pink FU-1402 is a kind of inorganic red ceramic pigment made of Iron red, SiO2, zirconium dioxide and mineralizing agents under the process of mixing, calcination and micropowder treatment. In the process of calcination, SiO2 and zirconium dioxide occur Chemical reaction. It wraps the Fe3+ inside it and makes it into the substance of zirconium silicate crystal structure. The tones will turn yellowish or reddish when changing the percentages of the composition of the coral pink. The mineralizers may include one or a combination of alkali metal halides or alkaline earth halides. FULLN GLAZE ceramic glaze pigment coral pink is suitable for oxidizing atmosphere firing. And it is suitable in all kinds of glazes especially for the zirconium glazes.

With perfect production process and advanced testing equipment, strong talent team and strict quality control system, we can ensure that our ceramic glaze pigment coral pink have stable quality and full ranges of colors. These series of ceramic glaze color coral pink materials are with fineness of less than 400 mesh, moisture is less than 0.5%. It can be used in the field of ceramic floor tiles, ceramic wall tiles, art porcelains, sanitary wares.

How to improve the coral pink?

Improving the reactivity of ferric oxide with Zr02 is the core of the synthesis process of coral pink.The key point of these techniques is: To pre-fire Zr02 and iron oxide at appropriate temperatures.Use the dry method to pregrind Zr02 and the iron oxide.Select the more active iron oxide.

DTA showed that the ingredients of zirconium iron red (coral pink) reacted at 300℃, 410℃, 570℃ and 700℃.Pre-fire Zr02 and ferric oxide at 570℃.Then it can get the improved coral pink by adding the SiO2 and mineralizer.

The improved zirconium coral pink material can also be obtained by mixing iron oxide and Zr02 by dry ball mill before preparing the color material.The method of premixing all the raw materials with ball mill does not have the above effect.

The red value (a) of the coral pink material made of yellow iron oxide (FeOOH) is higher than that made of red iron oxide (Fe2O3).The smaller the particle size of iron oxide (appropriate), the higher the red value (a) of the synthetic color.

People get the limit concentration of zirconium iron red (coral pink) material through the above techniques.The core of these technologies is to ensure the reaction between iron oxide and Zr02 takes place more fully and completely.The optimum temperature of the reaction was 570℃ by the pre-firing.
