Zirconium Oxide

Zirconium Oxide: An Overview

Zirconium oxide, also known as zirconia (ZrO2), stands as a versatile ceramic material with exceptional properties. This compound is synthesized when zirconium, a silvery transition metal, undergoes oxidation. The resulting product, zirconium dioxide, is notable for its high melting point, strength, and resistance to corrosion.

Properties and Applications

The unique characteristics of zirconium oxide ceramic make it suitable for a variety of applications. Its high resistance to crack propagation, or fracture toughness, is essential in the manufacturing of cutting blades, bearings, and zirconium oxide crucibles. In the medical field, zirconia ZrO2 ceramic is used for dental crowns and hip replacements due to its biocompatibility and wear resistance.

Types of Zirconium Oxide

There are several forms of zirconium oxide, each with distinct properties tailored to specific uses. Yttrium stabilized zirconium oxide is one such variant, where yttrium oxide is added to enhance the thermal stability and maintain the strength of the zirconia at high temperatures. This makes it ideal for use in thermal barrier coatings and oxygen sensors. Other forms, like zirconium tungstate, exhibit negative thermal expansion, contracting when heated, which is useful in composite materials where thermal expansion needs to be controlled.

Industrial Relevance

The industrial significance of zirconium oxide cannot be overstated. Its resistance to heat and wear makes it a prime choice for furnace linings and foundry molds. In the realm of electronics, zirconium IV oxide is utilized in fuel cells and oxygen sensors due to its ionic conductivity. The compound's refractory nature also lends itself to the production of abrasives and insulation materials.

Environmental and Safety Considerations

When dealing with zirconium oxide applications, it is crucial to consider environmental and safety aspects. Zirconium oxide is inert and stable, posing minimal risk to the environment. However, appropriate handling and disposal procedures should be followed to ensure safety, especially in powdered form to prevent inhalation.

Choosing the Right Zirconium Oxide

Selecting the appropriate zirconium oxide for a specific application requires understanding its various forms and properties. While Alibaba.com facilitates the connection between buyers and suppliers, it is essential for buyers to communicate their specific needs to find the right type of zirconium dioxide ceramic or other zirconia products.
