FRSG is a world-leading manufacturer of zirconium oxide powders. FRSG offers the largest line of zirconia powders, with composition ranging from monoclinic zirconia to yttria-stabilized zirconia (from 3 mol% to 8 mol%) to pigmented zirconia. With two industrial zirconium oxide manufacturing processes based on either thermal or chemical treatments of natural zirconium silicate, FRSG provides zirconium oxide powders featuring a wide range of purity (97.0% to 99.9%), particle size distribution (from large particles of 15μm to less than 1 micron) and reactivity (from 1m2 / g to 25 m2 / g for certain chemical processed zirconia).
FRSG's line of zirconium oxides addresses the specificities and requirements of many ceramic applications in markets such as aeronautics, automotive, electronics and communications. A technical leader with unparalleled material expertise and market knowledge, FRSG can recommend the right zirconia for an existing application or partner with customers on co-development for new applications.
Monoclinic Zirconia
Essential for Many Ceramic Applications
Monoclinic zirconia refers to pure zirconium dioxide (ZrO2) that does not contain any dopant or additive and exhibits a monoclinic crystallographic structure under temperatures up to 1170 ° C. Thanks to its outstanding physical and chemical properties, monoclinic zirconia powder is used in a large variety of ceramic applications: pigments for tile decoration, refractories, PZT and dielectric materials, abrasive materials, thermal barrier coatings and advanced technical ceramics.
The most comprehensive zirconia powders portfolio
FRSG operates two industrial zirconium oxide manufacturing processes based either on thermal or chemical treatments of natural zirconium silicate. This allows FRSG to offer the most comprehensive portfolio of monoclinic zirconium oxides in terms of chemical purity, particle size distribution and specific surface area, for consistent quality and performance.
Yttria-Stabilized Zirconia
Outstanding Mechanical Performance
Among all ceramic oxide materials, tetragonal zirconia stabilized with the addition of 3mol% Y2O3 (Y-TZP) exhibits at room temperature the highest performance in terms of:
Bending strength
Toughness
Tetragonal zirconia also enables the manufacturing of ceramic parts with:
Excellent surface finishing
Superior wear resistance
Outstanding corrosion resistance
FRSG offers world-leading 3mol% yttria-stabilized zirconia powders ranging from dry powder (CY3Z) suitable for injection molding or casting process to ready-to-press granules (GY3Z) used in uniaxial and isostatic pressing. Pigmented zirconia for decorative fine ceramic applications is also available.
All powders are manufactured using a state-of-the-art chemical process to ensure excellent performance and consistent high quality.
