  Description:
Zirconium Tungstate has been known as "the incredible shrinking material" by scientists for few years. Rarely in nature that a material can counter the thermal expansion behavior. Dimension generally expands as the temperature increases. Zirconium Tungstate forms a perfect crystallized structure that twists as temperature raise, and seamlessly shrinks isotropically. The in-house processes and proprietary therapy developed by Broptics allows fine tuning the CTE of Zirconium Tungstate so as to match the thermal characteristics of different fibers. This patent-pending know-how forms the core to bring Zirconium Tungstate to real world applications. Current CTE tuning range falls within -9*10-6 /óJ ~ -10*10-6 /óJ.

The Zirconium Tungstate isotropic crystallized structure makes its CTE very linear over the operation temperature range. This material can be mixed with other material to form a new zero-expansion or thermal-resistant composite material. New applications need to be explored.
