Zirconia powder (ZrO2) for technical ceramics
Ozark Ceramics Europe

OZARK TECHNICAL CERAMICS developed the production of High temperature Hafnium Oxide Insulators to service new advancements in high temperature thermometry. Hafnium Oxide Insulators are also useful as a non-toxic alternative to beryllium oxides in existing applications. OZARK Hafnium Oxide Insulators are routinely used for applications to 2200 C.

Hafnium Oxide, or Hafnia (formula HfO2), is a very refractory high temperature material which may be considered an exotic material in the fabricated form. OZARK developed a fabrication process for Hafnia in the early 80's and has been a steady source of Hafnia extrusions into a limited customer base. The material has gained wide acceptance in the upper temperature with reported uses to 2500 C.
