Yttria-stabilized zirconia (Y-TZP) is a high-performance ceramic composed of zirconia matrix reinforced with yttrium oxide, engineered to prevent phase transformations that would otherwise cause brittleness. It is widely deployed in demanding applications requiring wear resistance, high temperature stability, and reliability in corrosive or biocompatible environments—notably in dental crowns and implants, precision bearing balls, cutting tool inserts, and oxygen sensor elements in exhaust systems. Y-TZP is chosen over alumina and other structural ceramics when engineers need superior toughness combined with hardness, particularly for components subject to cyclic loading or thermal shock; its transformation-toughening mechanism makes it significantly more damage-tolerant than conventional ceramics while maintaining chemical inertness and biocompatibility.

Regulatory Screening

Environmental

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
