Engineered Ceramic Components

Zircoa Engineered Ceramic ComponentsZirconium Oxide Compositions Solve a Wide Range of Material Requirements

Engineered ceramic components, based upon Zircoa’s own Zirconium Oxide, are strong, resist corrosion, impact, high temperature, fracture stress and the harshest liquid and gaseous environments. Markets served include: wear parts, battery tooling, fluid flow control, oil field supply, electrical, machine parts, machine shop grind blanks, sensors, spray nozzles and valve trim.

For more detailed information on the unique properties of Zirconium Oxide (A Grain Zirconia, ZrO2) please visit our Solutions page, or contact a product specialist to discuss your specific needs.

Outstanding Features of Zirconium Oxide Compositions

Crack Resistant — Zirconium Oxide compositions are transformation toughened for added strength and crack resistance. When subjected to fracture stresses, a unique change in crystalline structure occurs, inhibiting crack growth. The stressed area expands to close any cracks, preventing failure.

Chemically inert — Zirconium Oxide compositions easily withstand the harshest liquid and gaseous environments. In general, Zirconium Oxide ceramics resist attack by organic solvents, molten metals, caustics, and acids.

Wear Resistant — Zirconium Oxide compositions are extremely wear resistant in many applications where abrasive or corrosive materials are present and impact, sliding wear and erosion conditions exist.
