OX1427 Zirconium Oxide Powder, Zirconia (ZrO2)
Product Description
Zirconium Oxide Powder (ZrO₂), also known as zirconia, is a high-performance ceramic oxide widely used across industries demanding extreme thermal stability, hardness, and chemical resistance. This white, odorless crystalline powder is insoluble in water and acids, maintaining its structure and purity even in harsh environments.
With a high melting point, high resistivity, low thermal expansion coefficient, and high refractive index, zirconia is the go-to material for applications where durability, heat resistance, and structural integrity are critical.
Our high-purity zirconia powder (99.9% ZrO₂) is ideal for demanding applications in electronics, aerospace, advanced ceramics, and thermal coatings. It is available in multiple grades and particle sizes to match diverse technical requirements.

Key Applications
Industrial Ceramics
Used to manufacture cutting tools, dental ceramics, valve components, and other high-durability materials. Zirconia’s mechanical strength and thermal stability make it ideal for advanced ceramic systems.
Thermal Coatings & Refractories
Essential in thermal barrier coatings for turbine blades, engines, and insulation linings. High-purity zirconia powder forms a protective layer that resists extreme heat and oxidation.
Raw Material for Metal Zirconium
Acts as a precursor for producing metallic zirconium and other zirconium compounds used in corrosion-resistant alloys, chemical processing, and nuclear materials.
Lighting & Optics
Zirconia’s high refractive index and optical clarity enable its use in enamels, gas lamp mantles, and white glass production.
Crucibles & Kilns
Used in the production of refractory crucibles and kiln components that must withstand extreme temperature without deformation or contamination.
Packaging & Availability
ACM provides high-purity zirconia powder in multiple packaging sizes, tailored to laboratory, pilot-scale, and industrial needs.
Frequently Asked Questions
Q1: What is the difference between stabilized and pure zirconia powder?
A1: Stabilized zirconia includes dopants like Y₂O₃ to improve fracture toughness, while high-purity zirconia powder (like OX1427) offers higher electrical insulation and thermal resistance for extreme environments.
Q2: Can OX1427 be used in additive manufacturing or ceramic 3D printing?
A2: Yes, certain grades of our powder are optimized for 3D printing and sintering. Custom PSD available.
