Highly Polished Zirconia (ZrO2) Sheets

Product Description

Highly polished Zirconia (ZrO₂) sheets are advanced ceramic materials widely used in high-performance applications due to their exceptional hardness, wear resistance, chemical stability, and high-temperature resistance. These properties make zirconia an ideal choice for industries ranging from medical and aerospace to electronics and chemical processing.

Manufacturing Techniques: Polished Zirconia (ZrO₂) Sheets

Sintering: Zirconia powders are sintered—often stabilized with yttria (Y₂O₃)—to enhance toughness through transformation toughening. This process ensures high structural integrity and performance under stress.
Polishing: Precision techniques, including laser and mechanical polishing, are employed to achieve ultra-smooth surfaces necessary for optical, medical, and high-tech industrial applications.

Key Properties

High fracture toughness due to the transformation toughening mechanism
Excellent wear and corrosion resistance
Superior thermal insulation with low thermal conductivity
Outstanding chemical inertness
Biocompatible, making it suitable for medical and dental applications

Tolerances and Surface Finish

Zirconia sheets require precise fabrication to meet strict industry standards for dimensional accuracy and surface smoothness. Below are typical values:

Dimensional Tolerances

General Precision (as-sintered): ±0.2 to ±0.5 mm
Fine Precision (ground & polished): ±0.01 to ±0.05 mm
Ultra-Precision (e.g., optical and semiconductor use): ±0.002 to ±0.005 mm

Surface Finish (Ra – Roughness Average)

As-Sintered: Ra 1–3 μm
Fine Ground: Ra 0.1–0.5 μm
Polished (Mirror Finish): Ra 0.01–0.05 μm
Ultra-Polished (Optical Grade): Ra < 0.005 μm (5 nm)

Flatness

Standard: 10–50 μm per 100 mm
High-Precision Applications: 5 μm per 100 mm
Optical and Semiconductor Applications: 1–2 μm per 100 mm

Thickness Tolerance

General: ±0.1 mm
Precision-Machined: ±0.01–0.05 mm
Ultra-Precision: ±0.005 mm

Parallelism

Standard: 50–100 μm
Precision Applications: 10–20 μm
Ultra-Precision Applications: <5 μm

Edge & Corner Tolerances

Chamfered Edges: ±0.1 mm (prevents chipping)
Sharp Edge Tolerance: ±0.05 mm

Due to zirconia’s brittleness, edge processing is critical for safe handling and reliable performance.
