For procurement professionals in the chemical and materials industries, understanding the technical specifications of a raw material is paramount to making informed purchasing decisions. Zirconium Dioxide (ZrO2), a high-performance inorganic compound, is no exception. Its utility across diverse sectors like ceramics, refractories, and electronics hinges on precise properties that influence its performance in final applications.

Deconstructing Zirconium Dioxide (ZrO2) Specifications

When reviewing technical data for Zirconium Dioxide, several key parameters stand out. These are critical for quality assurance and ensuring the material meets the stringent requirements of various industrial processes:

• Purity (ZrO2 Content): This is perhaps the most crucial specification. High purity ZrO2, often specified as 99.60% or higher, is essential for advanced applications where impurities can compromise performance. Trace elements like Fe2O3, SiO2, CaO, and Na2O are also closely monitored, with typical specifications indicating very low acceptable limits (e.g., Fe2O3 at 0.01%). This high purity is why many look to buy Zirconium Dioxide powder from specialized manufacturers.
• Physical Properties:
  • Appearance: Commonly described as a white or yellowish-brown powder.
  • Density: Typically around 5.89 g/mL at 25 °C.
  • Melting Point: An exceptionally high 2700 °C, making it suitable for extreme thermal applications.
  • Boiling Point: Around 5000 °C, further highlighting its thermal stability.
  • Water Solubility: Generally insoluble in water.
• Stability and Storage: ZrO2 is typically stable under normal conditions and should be stored in a tightly closed container in a cool, dry, and well-ventilated area, away from incompatible substances.

How Specifications Dictate Applications

These detailed specifications directly inform the suitability of ZrO2 for various industries. For instance:

• The high purity and melting point make it an excellent choice for refractory materials, kiln linings, and crucibles where extreme heat and chemical resistance are required. Procurement teams searching for 'refractory grade Zirconium Dioxide' will verify these thermal properties.
• Its consistent chemical composition and fine particle size (though not explicitly detailed in the provided snippet, it's a common spec) are vital for advanced ceramics and electronic components, ensuring predictable sintering behavior and desired electrical properties.
• Its inertness and ability to withstand high temperatures also make it valuable as a pigment additive and in enamel glass applications.

Procurement Considerations: Where to Buy Zirconium Dioxide

When you need to buy Zirconium Dioxide, partnering with a reputable manufacturer in China can offer significant advantages in terms of quality, availability, and competitive price. Key considerations when selecting a Zirconium Dioxide supplier include:

• Verification of Specifications: Always request a Certificate of Analysis (CoA) to confirm that the delivered product meets the specified purity and physical property requirements.
• Production Capacity: For industrial-scale needs, ensure the supplier can handle your volume requirements consistently.
• Technical Support: A supplier knowledgeable about ZrO2 applications can provide valuable insights and ensure you select the optimal grade.

Understanding these specifications is not just about compliance; it's about ensuring your final products perform to expectations. For procurement managers, detailed technical data sheets and a commitment to quality from your Zirconium Dioxide supplier are the foundations for successful sourcing.
