Torayceram(R) beads and balls can be used in grinding and dispersing applications. Also microgrinding and microdispersing efficiency has been achieved in micro media size.
Typical applications are as follows.
³0.03mm*, ³0.05mm* , ³0.1mm , ³0.2mm , ³0.3mm , ³0.4mm , ³0.5mm , ³0.65mm , ³0.8mm , ³1.0mm , ³1.25mm , ³1.5mm , ³1.75mm , ³2.0mm , ³2.35mm , ³2.5mm ³3.0mm , ³4.0mm , ³5.0mm , ³10mm
*For size less than ³0.05mm, please contact us.
HIP processing is a technology of sintering beads and balls in inactive gas atmosphere (like nitrogen), with pressure applied on them. HIP processing increases crushing strength. We can offer HIP-processed items for every size of Torayceram(R) beads. With this processing, their color of appearance becomes dark gray.
The material of Torayceram(R) beads and balls is mainly tetragonal zirconia made from zirconium oxide to which yttrium oxide is added, achieving the highest strength of all ceramics materials. Furthermore, they are almost free from contamination of impurities such as SiO2, Fe2O3 and MgO.

Toray is constantly progressing into new frontiers of advanced materials, backed by its long experience and superior technical know-how in the fields of synthetic fibers and plastics.
Torayceram® ceramics materials with high performance are one successful achievement of Toray's wide-range material development technology.
Toray initiated the Ceramics Department in 1981, starting with the development of synthetic technology for zirconia powder. Since then, we have focused on the development and the marketing of various zirconia products including oxygen sensors, cutters for textile machines, and beads for pulverization and dispersion, as well as the mass-production of zirconia powder. Now we are handling the wide range of materials in addition to zirconia, and their applications are also becoming more various. The ceramics materials we handle and the products of these fine ceramics are collectively called as Torayceram®.
These high performance and multi-function ceramics materials are produced by Toray's original technology starting from the synthesis of powder materials to forming, sintering and final processing of the products. Torayceram® has assorted variety of ceramics materials. Torayceram® includes such products of fine ceramics as zirconia (ZrO2), alumina (Al2O3), silicon carbide (SiC) and silicon nitride (Si3N4). Toray is expanding the potential use of Torayceram® to meet the needs of customers.
