CS Zirconia

CS grades are obtained through the purification of CC thermal zirconia leading to powders with increased purity together with a better control of the specific surface area (SSA).Similarly to CC grades, CS powders show zirconia particles with unique and uniform dentritic morphology offering higher reactivity than fused zirconia.

A large range of d50 and SSA is achievable:• D50 from 3.5µm to 0.6µm• Typical specific surface area from 1.5 to 6.5 m2/g

CS GRADES EXHIBIT SUPERIOR PURITY COMPARED TO CC GRADES

CS powders are used in applications requiring reactive premium grades of thermal zirconia with high level of purity.

CF Zirconia

CF grades are thermal zirconia powders produced by the fusion of zirconium silicate using plasma arc followed by chemical treatments.The plasma technology enables achieving the highest reactivity among all thermal zirconia grades regardless of the particle size.

CF zirconia offers high specific surface area typically around 6 m²/g and particle size ranging from 7.0 to 1.0 µm.Soft agglomerates around 95µm are also available for specific applications (see CF grade on next page).

CF POWDERS EXHIBIT HIGHER REACTIVITY THAN CC GRADESTHANKS TO FINER DENDRITIC MORPHOLOGIES

CF powders are recommended for applications requiring pure thermal zirconia with high reactivity.
