Applications

Tiles Production

Marquina ceramic supply a variety of pure Zircon and mineral combination opacifiers developed specifically by application. This insures the most efficient use of the Zircon mineral and thus reduces the overall cost of producing ceramic and porcelain tiles.

Sanitary Ware

Superfine and mineral combination opacifiers are increasingly being used in Sanitary ware glaze systems due to the various advantages that they bring to the finish product characteristic. These include enhanced whiteness and a smoother glaze surface on the microscopic level, which in turn gives an “easy clean” surface, less prone to staining during the product life cycle.

Tableware

Similar to Sanitary ware our range of superfine and mineral combination opacifiers are being increasingly used in Tableware glazes. The most significant advantage along with the potential for smoother glaze surface is the reduction in metal marking during use.

Brake Lining & Friction applications

Marquina Ceramic offer a range of tailor made milled Zircon powders for use in the brake lining sector where Control of the sand source and a particle size distribution are critical and vary for each specific brake lining formulation. The complexity of these and the difficulty understanding the various material interactions mean that ourproduct consistency is crucial to avoid failure in use.
