AI Overview

Dental zirconium oxide (zirconia,

ZrO sub 2

) powder is an advanced ceramic material widely used to fabricate dental crowns, bridges, and implants. Prized for its exceptional flexural strength, biocompatibility, and natural aesthetics, the powder is typically combined with a stabilizer like yttria to prevent phase transformation during milling and heating.

Flexural Strength: Often exceeds
, making it highly resistant to chewing forces.
Crystal Structure: Pure zirconia undergoes structural changes at high temperatures. To achieve dental stability, it is usually yttria-stabilized, most commonly in
(3 mol% yttria-stabilized tetragonal zirconia polycrystals) for maximum strength or
for enhanced translucency.
Biocompatibility: Highly inert and hypoallergenic, causing minimal soft-tissue irritation.
Aesthetics: Possesses a bright white color that mimics natural teeth, though it usually requires veneering or characterization to achieve a perfect match.

Granulation & Pressing: The raw powder is granulated and cold-isostatically pressed (CIP) or slip-cast into soft, machinable blocks.
CAD/CAM Milling: Dental laboratories use milling machines to carve the block into the desired crown or framework shape while it is still in a chalk-like, "pre-sintered" state.
Sintering: The milled prosthetic is placed in a high-temperature furnace (up to
), which burns out the binder and causes the powder particles to fuse tightly together. This shrinking and densification process gives the restoration its final, diamond-hard durability.

Purity: Generally
trace metal basis.
Particle Size: Ranges from nanoscale to a few microns (typically
) to ensure flawless density and polishability.
Supplier Options: You can source fine-grade zirconium oxide powder from established chemical distributors and specialized material suppliers:
- For scientific research and lab testing, explore standard chemical options on Sigma-Aldrich.
- For industrial advanced ceramic and casting requirements, browse the catalog on Princeton Powder.
- If you are a dental laboratory seeking already-formulated veneering ceramic powders or correction liquids, check DDS Dental Supply to review available chairside and lab brands.
