Ceramic Media

Next Generation Ceramic Media

Why Ceramic Bead?

The beads or ball, have been chosen as a media for the process of mixing, crushing, dispersing and purifying variable materials. Steel media is commonly used but can not be used for manufacturing bright colors and steel contamination could be a problem for some products. Ceramic beads reduce contamination to products and perform as well as steel.

What is Zirconia?

NAME OF ZIRCONIA

Generally speaking, oxides are named by changing the suffix of the constituting metal element "-ium" to "-a" , such as alumina for aluminium oxide and titania for titanium oxide. Zirconia is therefore the same as Zirconium Oxide (Zr02).

APPLICATION OF ZIRCONIA

Zirconia is used in Grinding media, Cutting Tools, Ferruls, Oxygen Sensor, Cubic Zirconia(as Jewelry) and Refractory Materials, because zirconia has high hardness, strength, toughness, excellent wear resistance (structural properties), electrical conductivity(electrical properties), and low thermal conductivity (thermal properties). Specially, Zirconia Beads make the best use of structural properties in specific characters of Zirconia.

CLASSIFICAFICATION OF ZIRCONIA

FSZ (Fully Stabilized Zirconia)
PSZ(Partial Stabilized Zirconia)
TZP(Tetragonal Zircoia Polycrystal) or TTZ(Tetragonal Toughened Zirconia)
Zircon( Zirconium Silicate)Although the name resembles zirconia (zirconia is called "zircon" in france)
