Ceramic Industry


Lead Oxide

Lead is used in a wide range of glaze formulations for items such as tableware (earthenware and china), wall and floor tiles, porcelain and some sanitary ware.

The lead compounds used are largely litharge, red lead and lead silicates. The advantageous properties offered by lead compounds are lower melting points and wider softening ranges, low surface tension, good electrical properties and a hard wearing and impervious finish.

Zinc Oxide

In the ceramic industry, zinc oxide is used in the manufacture of glasses, glazes, frits, porcelain enamels and magnetic ferrites. The largest consuming plants are in the tile industry.

Zinc oxide is used in various types of glazes. In general, it provides

•  Fluxing power
•  Reduction of expansion
•  Prevention of crazing
•   A higher degree of gloss and whiteness
•  A positive effect on elasticity
•  Increased maturing range
•  Increased brilliance of colours
•  Correction of eggshell finish
