Engineered with specific stabilizers (Y2O3 or MgO) to tailor phase structures. Our portfolio includes high-strength Y-TZP, hydrothermally stable Mg-PSZ, and fully stabilized Y-FSZ for extreme chemical environments (pH 0–14).
Renowned as "Ceramic Steel" for its exceptional fracture toughness, Rauschert Zirconia series is engineered with specialized stabilizers (Y2O3 or MgO) to tailor phase structures for specific demanding environments.
1. Zirconia Y (Y-TZP)
Zirconia Y utilizes transformation toughening to achieve superior mechanical strength. Under stress, tetragonal grains transform into the monoclinic phase; the resulting 3–5% volume expansion creates compressive stress that effectively "clamps" micro-cracks and prevents propagation. Its sub-micron, high-density grain structure allows for a mirror-grade finish, significantly reducing friction coefficients and extending wear life. It is available in white or black for premium aesthetics or light-shielding industrial applications.
2. Zirconia M (Mg-PSZ)
Zirconia M (Mg-PSZ) is the preferred choice for heavy-duty mechanical applications due to its superior stability under high temperature, high pressure, and humidity. Its microstructure—fine tetragonal precipitates within a cubic matrix—effectively inhibits spontaneous phase transformation and surface deterioration.
