Release time:
2026-10-13
This complete guide covers core properties, industrial applications, selection standards and supplier notes for Spherical TiO2 Powder. We share 12 years of in-house production experience from Jinghuang Nanomaterials, helping you avoid quality pitfalls and pick the right product for your specific project needs.
📋 Overview
This guide explains what spherical TiO2 powder is, its key advantages over conventional TiO2, common applications, and how to select a qualified product for your project.
What Is Spherical TiO2 Powder?
Spherical TiO2 Powder is titanium dioxide powder with uniform spherical particle morphology. It is produced via controlled synthesis processes like spray pyrolysis to maintain consistent shape and size, unlike milled irregular TiO2 powder. In practice, we found that spherical morphology delivers significant performance improvements for precision manufacturing processes.
Q: How does spherical TiO2 differ from irregular TiO2?
The core difference lies in particle shape, which impacts key functional properties. Industry consensus confirms that spherical TiO2 outperforms irregular TiO2 in flowability, packing density, and slurry stability. Per our 2026 in-house test data, spherical TiO2 has 15-20% higher bulk density than comparable irregular TiO2 of the same particle size.
Key Performance Advantages of Spherical TiO2 Powder
- Improved flowability for press forming, reducing mold wear and extending equipment service life by 12% on average, according to our production case data
- Uniform light scattering and refractive index, delivering more consistent gloss and UV protection for coating formulations
- Higher packing density, which is critical for manufacturing dense, high-strength ceramics and battery components

Core Property Specifications for Common Grades
We categorize our spherical TiO2 powder by particle size to match different application requirements. Below is a comparison of standard grades we produce in 2026:
| Particle Size (D50) | Purity | Specific Surface Area (m²/g) | Recommended Application |
|---|---|---|---|
| 100-200 nm | 99.9% | 10-15 | UV Protective Coatings |
| 1-5 μm | 99.8% | 1-3 | Electronic Ceramics |
| 10-30 μm | 99.5% | 0.2-0.8 | 3D Printing & Powder Metallurgy |
2025 recent research published in the Journal of Nanomaterials confirms that spherical TiO2 improves the sintering density of piezoelectric ceramics by 3-5% compared to irregular TiO2.
Common Industrial Applications of Spherical TiO2 Powder
Spherical TiO2 powder is used across a wide range of industrial and research applications, thanks to its consistent morphology and chemical stability. From our customer data, the top three use cases are electronic ceramics, functional coatings, and energy materials.
Q: Is spherical TiO2 suitable for photocatalysis applications?
Modified spherical TiO2 can be used for photocatalysis, but unmodified spherical TiO2 is not ideal for most high-activity photocatalysis use cases. Recent 2026 data shows that porous spherical TiO2 has better mass transfer efficiency than irregular TiO2 in water treatment, but it requires specific surface modification to achieve comparable activity. We do not recommend unmodified spherical TiO2 for high-demand photocatalysis projects.
Q: What benefits does it offer for 3D printing ceramics?
Actual testing with our ceramic 3D printing customers shows that spherical TiO2 powder delivers more consistent flow in powder bed 3D printing, reducing porosity in final parts by 7% compared to irregular TiO2. This improves the mechanical strength and dimensional accuracy of the final printed component.
How to Select High-Quality Spherical TiO2 Powder
To avoid performance issues in your end product, you need to check four core quality indicators before purchasing. In practice, poor control of any single indicator can lead to costly production defects.
Key Quality Indicators to Verify
You should prioritize checking these four metrics: 1) Purity: even 0.1% excess impurity can reduce ceramic sintering density by 2%, per our lab tests; 2) Sphericity: low sphericity negates the flow and packing benefits; 3) Particle size distribution: a narrow distribution ensures consistent performance; 4) Moisture content: excess moisture causes agglomeration in storage.
What to expect from a reliable supplier
A reputable spherical TiO2 supplier should provide a full COA (Certificate of Analysis) with every batch, including test data for all core indicators. At Jinghuang Nanomaterials, we test every batch via SEM and laser particle size analysis before shipment, to ensure it meets agreed specifications.
