Synthesis of Hematite-Zircon-Silica Nano Composite as a Non Toxic Ceramic Pigment... 

In order to prepare a hematite-cristobalite-zircon inclusion red ceramic pigment, Sol-Gel process with the colloidal silica, Zirconium cloride and iron (11) sulfate were been synthesized. 

The number of academic entries in the Google-Academic search tool is around 1200 (as of March 2014) (Figure 37.1), and the academic publications is about 98% of total publications. We can consider three main steps in the development of ceramic pigments for glazed ceramics (i) before the discovery of European porcelain (1710), after this discovery up to 1900 with the introduction of the green of Sevres as the main relevant novelty in 1802, (ii) the twentieth century with the discovery of the zircon stain family, and (iii) the twenty-first century with the development of submicrometer size pigments for inkjet applications.

Another desirable property for a ceramic color is a high refractive index. For example, valuable pigments are based on spinels [1302-67-6] ( 2jj = 1.8) and on zircon ( 2j = 1.9), but no valuable pigments are based on apatite ( 2j = 1.6), even though the lattice of apatite is as versatile for making ionic substitutions as that of spinel.
