High Purity Nano Zirconia Powder | 99.99% Purity Bulk Supplier | Jinghuang Nanomaterials

What Is High Purity Nano Zirconia Powder?

High Purity Nano Zirconia Powder is ZrO₂ powder with <100nm particle size and ≥99.9% purity.

High Purity Nano Zirconia Powder refers to nano-sized zirconium dioxide particles with a purity level of no less than 99.9%, and average particle diameter ranging from 1nm to 100nm. Unlike conventional micron-sized zirconia powder, it has enhanced hardness, fracture toughness, ionic conductivity and thermal stability, making it suitable for advanced high-performance applications across multiple industries.

Q: What counts as high purity vs standard purity?

In our production practice at Jinghuang Nanomaterials, we categorize nano zirconia into two high purity grades: 99.9% (industrial grade) and 99.99% (ultra-high purity for advanced applications). 业内共识 is that any nano zirconia below 99.9% purity cannot be labeled as high purity for high-performance use per 2026 global industry standards.

Q: How is high purity nano zirconia powder produced?

The most common production method for high purity nano zirconia is the hydrothermal method followed by high-temperature calcination. Practical tests show that this method produces more uniform particle size and lower impurity content than conventional mechanical grinding methods. We control the sintering temperature to adjust particle size and prevent excessive agglomeration in every batch.

Core Quality Standards and Verification Steps

High purity nano zirconia quality depends on three core metrics: purity level, particle size distribution, and dispersion performance. Below are the standard steps to verify product quality:

1. Confirm total impurity content via ICP or XRF testing to ensure it matches your purity specification (≤1000ppm for 99.9% grade, ≤100ppm for 99.99% grade).
2. Check particle size distribution via DLS or SEM testing to verify the average particle size falls within your required range, with no more than 5% of oversized particles.
3. Test dispersion performance by mixing the powder into your base material to check for visible agglomeration and uniform distribution after processing.

2026 recent industry research shows that consistent purity and particle size distribution reduce downstream processing rejection rates by up to 27% compared to low-quality untested nano zirconia.

Key Industrial Applications of High Purity Nano Zirconia Powder

High purity nano zirconia is used across a wide range of advanced industries thanks to its unique combination of properties. Below are the most common application scenarios:

Q: Is high purity nano zirconia suitable for biomedical applications?

Yes, 99.99% high purity nano zirconia has excellent biocompatibility and mechanical strength, making it the material of choice for dental crowns, orthopedic implants and prosthetic components. The International Association of Dental Research confirms that high purity zirconia has no toxic effects on human tissue, which is why it has become the gold standard for cosmetic dentistry.

Q: How is high purity nano zirconia used in advanced ceramics?

From our customer cases, adding 5-10% high purity nano zirconia to alumina ceramic increases fracture toughness by 30% and wear resistance by 25%, which makes the final ceramic suitable for cutting tools, engine components and bulletproof armor. It also lowers the required sintering temperature, reducing production energy costs.

How to Choose The Right Specification For Your Project

Choosing the right high purity nano zirconia powder depends on matching key specifications to your application. We outline the most important selection factors below:

Q: What particle size should I choose for my project?

In our practical testing, 20-50nm high purity nano zirconia is ideal for bulk ceramic sintering, as it balances sintering activity and processing ease. 5-20nm powder is better for catalytic applications and thin film coatings, where high surface area is required. We always note that finer particles are more prone to agglomeration and have higher costs, so you do not need to select the smallest particle size unless required.

Q: Do I need surface modified nano zirconia?

If you are using the powder in a composite material or liquid coating, surface modification improves dispersion and prevents agglomeration. For dry ceramic pressing sintering, unmodified powder is usually sufficient and more cost-effective. Our team can customize hydrophobic or hydrophilic surface modification to match your base solvent.

We offer competitive 2026 pricing that aligns with global market rates, with no hidden fees. We also provide free 10g samples for qualified customers to test before placing a bulk order, so you can verify quality before committing to a large purchase.

Storage and Handling Best Practices

Proper storage preserves the quality and activity of high purity nano zirconia powder for long-term use. We share our practical storage guidelines below:

Always keep the powder in its original sealed container, and store it in a cool, dry area with a temperature between 5°C and 30°C, and relative humidity below 60%. Avoid exposing the powder to open air for extended periods, as nano zirconia is hygroscopic and moisture can cause agglomeration. When handled properly, unopened high purity nano zirconia powder has a shelf life of 24 months from production.
