We share 12 years of practical production experience from Jinghuang Nanomaterials, compare product specifications, and answer the most common questions buyers have.
📋 Overview
This guide is built on 12 years of practical production and testing experience of spherical nanomaterials from Jinghuang Nanomaterials, to help buyers and researchers understand Spherical TiO2 Powder clearly.
What Is Spherical TiO2 Powder?
Spherical TiO2 Powder refers to a high-performance titanium dioxide nanomaterial with controlled uniform spherical particle morphology, instead of irregular angular shapes. Unlike conventional TiO2 powder produced by standard milling processes, high-quality spherical TiO2 is synthesized via advanced chemical or physical processing to achieve consistent particle size and flowability. In practice, our production team finds that the spherical shape reduces agglomeration and improves dispersion in end applications, which is a key advantage over irregular TiO2 powder.
Q: What is the core difference between spherical TiO2 and conventional TiO2 powder?
A: The main difference is particle morphology. Conventional TiO2 has irregular, angular particles that tend to agglomerate and have poor flowability. Spherical TiO2 has smooth, uniform particles that deliver better dispersion, higher packing density, and improved performance. From our test data, spherical TiO2 shows 30% higher packing density than irregular TiO2 of the same average particle size.
Core Properties of High-Grade Spherical TiO2 Powder
High-quality Spherical TiO2 Powder has several key adjustable properties that make it suitable for different industrial uses. From case studies of our client projects, the most critical properties that impact end performance are purity, particle size, and specific surface area.
| Property Spec | High Purity Grade | Industrial Bulk Grade |
|---|---|---|
| Purity | 99.9% - 99.99% | 98% - 99% |
| Common Particle Size Range | 10nm - 1μm | 1μm - 100μm |
| Bulk Density | 0.8 - 1.2 g/cm³ | 1.2 - 1.8 g/cm³ |
| Typical Applications | Electronic ceramics, catalyst carriers | Coatings, pigments, additive manufacturing |
Q: Is spherical TiO2 powder always nano-sized?
A: No, spherical TiO2 powder can be produced in both nano-sized (below 100nm) and micron-sized (1μm to 100μm) ranges, depending on application requirements. 2026 industry data shows that micron-sized spherical TiO2 is more widely used in ceramic and coating applications, while nano-sized variants are mostly used in photocatalysis and batteries.

Key Industrial Applications of Spherical TiO2 Powder
Spherical TiO2 Powder is used across a wide range of high-tech and traditional industrial sectors, thanks to its adjustable properties and excellent chemical stability. Below are the most common high-volume applications in 2026:
- Electronic ceramics: Raw material for dielectric ceramics and ceramic capacitors, thanks to high packing density and uniform sintering
- Photocatalyst: Nano-sized spherical TiO2 is used for water purification, air purification, and self-cleaning coatings
- Lithium-ion battery materials: Coating agent for electrode materials to improve cycle stability
- Additive manufacturing: Raw material for 3D printed ceramic parts, thanks to excellent flowability
- High-performance coatings: Improves scratch resistance and weatherability of industrial and architectural coatings
Q: Can spherical TiO2 powder be used in food contact applications?
A: Only food-grade spherical TiO2 powder that meets regional regulatory standards (such as FDA standards in the US) can be used in food contact applications. Industrial grade spherical TiO2 is not approved for food contact use, so buyers must confirm the grade with their supplier before purchase.
How to Select the Right Spherical TiO2 Powder for Your Project
Follow these practical steps to pick the best Spherical TiO2 Powder for your specific application, based on our years of experience working with hundreds of clients:
- Confirm your required purity and particle size range based on your end product performance requirements. For high-tech electronic applications, you will usually need 99.9%+ purity.
- Request a small sample from the supplier to conduct in-house performance testing before placing a bulk order. This helps you avoid compatibility issues with your existing production process.
- Verify the supplier’s quality control system and documentation. Reputable suppliers will provide third-party test reports for every batch of product.
- Confirm that the supplier can meet your required order volume and delivery timeline, especially for large bulk industrial orders.
Q: Can I get custom-sized spherical TiO2 powder from suppliers?
A: Most professional nanomaterial suppliers, including Jinghuang Nanomaterials, offer custom particle size and surface modification for spherical TiO2 powder to meet specific application requirements. In practice, custom specifications are often needed for niche high-tech applications, so you should communicate your needs early.
