99.99% Purity Zirconium Oxide: Premium Nano Powder for High-End Industrial Use

Basic Definition & Core Properties of 99.99% Purity Zirconium Oxide

99.99% Purity Zirconium Oxide refers to zirconia powder with total impurity content below 100ppm, meeting top-tier global industrial manufacturing standards. As a white crystalline nano powder, it features exceptional chemical inertness, melting point above 2700℃, 1200MPa flexural strength and ultra-low thermal conductivity, far better than low-purity zirconia grades. In practical test at Jinghuang Nano lab, 99.99% purity zirconium oxide can keep 99% of its mechanical performance after 1000 thermal shock cycles between -40℃ and 1200℃.

Key Verified Technical Specifications (2026 Test Data)

All qualified 99.99% Purity Zirconium Oxide products shall meet the following standard indexes: average particle size between 30nm and 500nm for custom selection, specific surface area 8-18 m²/g, hafnium impurity content ≤30ppm, iron element content ≤5ppm, no detectable heavy metal impurities. Industry consensus is that these indexes are non-negotiable for semiconductor and aerospace material use cases.

Q1: What makes 99.99% Purity Zirconium Oxide different from low-purity grades?

Unlike 99% or 99.9% purity zirconia which contains high content of silicon, iron and hafnium impurities, 99.99% Purity Zirconium Oxide will not generate volatile by-products under ultra-high temperature working environment, and will not cause performance attenuation of core components.

Standard Production Workflow of 99.99% Purity Zirconium Oxide

The production of 99.99% Purity Zirconium Oxide requires strict full-process impurity control, any missing step will lead to unqualified final product. From cases of Jinghuang Nano’s 12-year production history, the yield rate of mass production of 99.99% purity zirconia is only around 72% under standard operation.

1. Raw material pre-purification: Continuous 7-stage solvent extraction to separate and remove hafnium, iron and silicon impurities from industrial zirconium solution
2. Precipitation and washing: High-purity ammonia water is added to generate zirconium hydroxide precipitate, which is washed for 12 times with ion-exchanged pure water to remove soluble residual impurities
3. High-temperature calcination: The dried precipitate is heated under 1400℃ oxygen-isolated environment for 8.5 hours to form high-purity zirconia crystal phase
4. Pulverization and classification: Airflow milling technology is applied to pulverize calcined blocks to target nano particle size, followed by multi-stage vibration screening to remove oversized particles
5. Final quality inspection: ICP-OES spectrometer is used to test 32 different impurity elements one by one to confirm total impurity content below 100ppm
