Zircon porcelain

See also Ceramics Porcelain Enamel and Porcelain, Zircon. 

Zircon pigments are derived from the tetragonal zirconium silicate, ZrSi(>4. Because uf Lite high temperature (up to 1600°C) and chemical stability of zirconium silicate, zircon pigments can be used in the formulations of high temperature (1300- 14O0cC) glazes, Zirconium silicate is also used as an opacifier in porcelain and vitreous enamels. 

By this term, we mean other uses of oxides such as insulating substrates, capacitors, resistors, and conductors in electronic circuits. Insulating oxides are used in electrical circuits for such jobs as the separation of conductors, mechanical supports, heat sinks, and capacitor materials. Classical materials include naturally occurring minerals or manufactured composites such as zircon, steatite, mica, quartz, porcelain, and glass. The latter was particularly useful in low stress situations because of its low cost and the ease of forming it into desired shapes. 

Properties White powder. A strong flux in enamels, glazes, and porcelains. It can be used in place of lithium zirconate. 

Zirconium silicate or zircon, ZrSi04, found in India, Madagascar and Australia, is used in the manufacture of zircon porcelain for electrical insulation. 

Zircon Porcelain. An electroceramic made from a batch consisting of 60-70% zircon, 20-30% flux and 10-20% clay the flux may be a complex Ca-Mg-Ba-Zr silicate or other alkaline-earth composition. Zircon... 

Nonfeldspathic Porcelains. Because the feldspar-containing porcelains tend to be lossy because of their alkah ion content, a group known as nonfeldspathic, i.e., without feldspar, was developed. This group includes steatite, forsterite, cordierite, and zircon porcelain. Table 1.8 shows typical compositions of these materials. The variability in these compositions is caused by differences in the compositions of the clays used. 

Cordierite possesses very low thermal expansion coefficient and excellent thermal shock resistance. Zircon porcelains have the advantage of relatively low thermal expansion coefficient, excellent dielectric properties, good thermal shock resistance, high mechanical strength, and ease of fabrication. However, because of higher raw material costs, their use in electrical applications is not widespread.

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. 

If the discovery of European white porcelain was the fruit of the modern experimental method, the discovery of zircon stains can be considered the fruit of the application of the scientific knowledge (research) to technology (innovation). In effect, the introduction of zircon in ceramics resulted in the high...
