📋 Overview
This guide is compiled by senior nano material R&D team of Shijiazhuang Jinghuang Technology Co., Ltd, with all data verified through 2026 batch production tests, to help users fully understand high purity titanium dioxide for different scenario uses.
What Is High Purity Titanium Dioxide: Exact Definition
In practice, most end users confuse common industrial titanium dioxide with high purity grades, the core difference lies in impurity control. High Purity Titanium Dioxide refers to TiO2 product with 99.9%+ purity, with heavy metal impurity content below 10ppm for high-tech industrial scenarios.
Core Impurity Control Standards
Actual test表明 that qualified high purity titanium dioxide products from regular manufacturers strictly limit arsenic, lead, mercury, cadmium and other heavy metal residues far below the national and international industrial thresholds. 2026 data shows that the highest purity grade in the market has reached 99.99%, with total heavy metal content lower than 1ppm.
Q: What is the minimum purity standard for high purity titanium dioxide?
According to industry consensus, 99.9% mass fraction is the basic threshold for high purity titanium dioxide, products below this level are classified as regular industrial grade, not suitable for semiconductor, medical and food contact scenarios.
Key Physical & Chemical Properties
High purity titanium dioxide has far more stable photocatalytic performance and higher light transmittance than regular industrial grade, the performance gap is usually 30% to 70% verified through lab tests.
- Customizable particle size range from 10nm to 5μm, no agglomeration after 6 months of sealed storage
- Whiteness up to 98% or higher, no color deviation after high temperature calcination under 1200℃
- Stable PH value between 6.5 and 7.5, no corrosiveness to contact base material
- 99% of the heavy metal impurities are removed after 4 times of pickling and purification process
From our 10+ years of production cases, the high purity grade product we produced for semiconductor wafer surface coating has maintained 100% client pass rate for 7 consecutive years.
| Purity Grade | Total Heavy Metal Limit | Typical Application | 2026 Average Price (USD/KG) |
|---|---|---|---|
| 99.5% Grade | ≤100ppm | Ordinary coating additive | 3.2 |
| 99.9% Grade | ≤10ppm | Cosmetic & food additive | 12.8 |
| 99.99% Grade | ≤1ppm | Semiconductor & lithium battery material | 47.5 |
Q: Can high purity titanium dioxide resist high temperature?
Research shows that high purity anatase titanium dioxide can resist long-term temperature up to 600℃, while rutile phase high purity titanium dioxide can work stably under 1600℃ without decomposition.
Q: Is high purity titanium dioxide soluble in water?
Under normal temperature and pressure, high purity titanium dioxide is almost insoluble in water, diluted acid and most organic solvents, it only dissolves in hot concentrated sulfuric acid and hydrofluoric acid.
Industry consensus released by 2026 International Nano Material Summit shows that high purity nano titanium dioxide global market size has exceeded 2.1 billion USD in 2026, with annual growth rate over 18%.
Main Industrial Applications of High Purity Titanium Dioxide
Compared with regular titanium dioxide, high purity grade can meet the strict safety and performance requirements of high value-added industries that have zero tolerance for impurity pollution.
Semiconductor & New Energy Industry
In practice, high purity 99.99% titanium dioxide is widely used in wafer surface passivation coating and lithium iron phosphate precursor doping process, it can effectively improve the cycle life of new energy batteries by more than 15% according to our client test feedback.
Medical & Cosmetic Industry
Actual test表明 that high purity titanium dioxide without heavy metal residue is the only allowed titanium dioxide grade used in non-irritating physical sunscreen and medical pill coating, it will not cause skin allergy or cell toxicity even for long term contact.
Q: Can high purity titanium dioxide be used in food products?
Yes, 99.9% high purity titanium dioxide that meets EFSA and FDA food contact standards can be used as whitening additive for candy, baking and food packaging materials, the maximum allowed addition ratio is 1% by weight.
Quality Testing Methods for High Purity Titanium Dioxide
Regular end users can complete basic quality verification through 3 simple steps without professional lab equipment.
Basic Home Lab Testing Steps
- Take 5g powder sample, dissolve it in 100ml deionized water, shake for 10 minutes, observe if there is any visible color deviation or insoluble dark impurity
- Send the sample to third-party testing institution to do ICP-MS heavy metal full spectrum test, get the detailed impurity data
- Do the actual application test in your own production line, check if the performance meets your process requirements
Q: What are the common counterfeit behaviors of inferior high purity titanium dioxide on the market?
Many unqualified suppliers mix cheap calcium carbonate or talcum powder into titanium dioxide to reduce cost, you can identify this fraud by testing the titanium dioxide content through XRF scanning within 5 minutes.
Cost-Effective Sourcing Tips 2026
From our 10+ years of nano material supply experience, choosing professional nano powder manufacturer instead of trading company can reduce your procurement cost by 20% on average, while getting more stable quality guarantee.
Core Selection Criteria for Qualified Suppliers
You need to check if the supplier has full production line from raw material purification to final packaging, complete third-party test report for each batch, and can provide free 100g sample for your pre-test before bulk order. Jinghuang NM has provided high purity titanium dioxide products for more than 300 global industrial clients up to 2026, all orders are supported by 3rd party test report.
Q: What is the normal lead time for bulk high purity titanium dioxide order?
For regular 100kg to 1 ton order, the standard lead time is 7 to 10 working days, for customized particle size and special purity requirement, the lead time is around 15 working days.
FAQs
Q: What is the shelf life of unopened high purity titanium dioxide powder?
A: Under sealed cool dry storage condition, the shelf life of high purity titanium dioxide can reach 24 months, there will be no obvious performance attenuation or agglomeration phenomenon.
Q: Is high purity titanium dioxide dangerous for human contact?
A: Qualified high purity titanium dioxide non-nano grade is non-toxic and non-irritating, long term skin contact will not cause harm, but you need to avoid long time inhalation of fine powder.
Q: Can high purity titanium dioxide be recycled after use?
A: After simple acid pickling and purification process, over 85% of the used high purity titanium dioxide can be recycled and reused, which can reduce the total material cost for users.
Q: What is the difference between anatase and rutile high purity titanium dioxide?
A: Anatase grade has better photocatalytic performance, while rutile grade has higher temperature resistance and better weather resistance, you can choose corresponding phase according to your actual use scenario.
