氧化鋯等級

• 3Y-TZP（三氧化鋯穩定型）｜高強度與韌性
• Mg-PSZ / Y-PSZ（部分穩定型）｜大尺寸結構抗熱震
• 表面光潔度可達鏡面級 Ra < 0.01μm

Zirconia Ceramic (ZrO₂)｜Tough & Smooth Technical Ceramic Material

Material Properties

Zirconia (ZrO₂) is a high-toughness technical ceramic with excellent fracture resistance, strength, surface polishability, and biocompatibility. Compared to alumina, zirconia has superior impact tolerance and is ideal for precision mechanical, medical, and semiconductor components.

Application Fields

• Semiconductor jigs: alignment pins, standoffs, position locators
• Optoelectronic modules: sliders, bearing housings, shafts
• Automation tools: rollers, guides, bushings
• Medical & dental: implant parts, surgical tools, orthodontics
• Food equipment: anti-corrosive sliders, friction-resistant parts

Zirconia Grades

• 3Y-TZP (3 mol% yttria-stabilized): high toughness, fine grain
• Y-PSZ / Mg-PSZ: partially stabilized, thermal shock-resistant
• Polishable to mirror-grade surface: Ra < 0.01μm
