Cerium oxide (CeO₂) is a versatile material that performs a variety of functions in the manufacture of ceramic glazes and clays. It is particularly prized for its ability to act as an opacifier, creating white, satin or soft translucent effect glazes. Its role in ceramics is not only aesthetic, but also technical, as it can stabilize glazes and improve their thermal resistance. It is compatible with a wide range of temperatures, making it useful in both low and high temperature ceramics.
Cerium oxide has a crystalline structure that gives it refractory properties. This makes it particularly suitable for use in high-temperature glazes where stability is required. In addition, it is used in the manufacture of ceramic glazes and refractory materials due to its resistance to high temperatures and its ability to improve the durability of the pieces. In artistic ceramics, it is combined with other oxides to create unique decorative effects, such as subtle color changes or smooth textures.
Interesting Fact
Cerium oxide is also used in the optical industry as a component of lenses and mirrors due to its ability to polish surfaces at the microscopic level. This property as an abrasive makes it a popular material for restoring antique ceramics.
Helpful Tip
When working with cerium oxide, be sure to sieve it finely to avoid lumps in the glazes. Experiment with proportions to achieve the desired level of opacity. Due to its irritant potential, always wear personal protective equipment, such as mask and gloves, when handling it.
