2026-07-03
This full guide explains core definitions, production processes, performance advantages and typical use cases of Ultra High Purity Titanium Dioxide, based on 2026 industry research and Jinghuang Nano’s 8 years of nanomaterial manufacturing experience, helping industrial buyers select qualified high-purity products efficiently.
📋 Overview
This 2026 updated guideline covers all practical details about Ultra High Purity Titanium Dioxide, including industry verified parameters, quality selection rules and real application cases for different high-end manufacturing scenarios.
What Is Ultra High Purity Titanium Dioxide
Ultra High Purity Titanium Dioxide refers to titanium dioxide products with total impurity content lower than 100ppm and purity above 99.99%, which removes most heavy metal and non-metal contaminants that exist in regular industrial grade TiO2.
Ultra High Purity Titanium Dioxide is a high-value nanomaterial with 99.99% minimum purity and zero heavy metal residue, specially produced for strict high-end industrial demands. In practice, most standard industrial titanium dioxide only reaches 98% to 99.5% purity, which cannot meet the requirements of semiconductor wafer processing or aerospace thermal barrier coating. 2026 industry data shows that the global demand for 99.99% grade ultra high purity titanium dioxide has increased by 42% year on year compared to 2024, driven by the fast development of new energy and advanced electronics sectors.
Q: What is the purity threshold for qualified Ultra High Purity Titanium Dioxide?
A: According to ISO 14703:2020 nanomaterial standard, the official purity threshold for this product is ≥99.99% (4N), with single heavy metal impurity content no more than 10ppm, no soluble arsenic, lead or mercury detected.
Q: What color does qualified Ultra High Purity Titanium Dioxide show?
A: Real 4N grade product presents uniform pure white color, no yellow, gray or brown tint on powder surface, while impure low-grade high-purity TiO2 usually shows slight yellow edge due to ferric ion residue.
Standard Manufacturing Process for 4N Grade Ultra High Purity Titanium Dioxide
The whole production flow of qualified Ultra High Purity Titanium Dioxide requires full closed-loop operation in dust-free workshop, to avoid external impurity contamination during processing. Actual test表明, production lines that do not adopt 100k level dust-free environment will have 30% higher impurity rate than standard production lines.
- Raw material purification: Use multi-stage distillation to purify titanium tetrachloride feedstock, remove over 99.99% of iron, chromium and nickel impurities
- Constant temperature hydrolysis: Carry out pressure controlled hydrolysis under 180℃ sealed environment, no external particles allowed to enter the reaction system
- High temperature calcination: Heat the precursor under 1050℃ vacuum condition for 6 hours, to remove all residual chloride and organic components
- Plasma grading: Use 1200℃ plasma airflow to break particles to required nano size, then conduct vacuum packaging in nitrogen filled glove box
Core Performance Advantages of Qualified Ultra High Purity Titanium Dioxide
Compared with regular industrial grade TiO2, 4N grade Ultra High Purity Titanium Dioxide has far more stable chemical and physical properties in extreme working conditions. 业内共识是 that high-purity TiO2 with less impurity can extend the service life of end products by 2 to 3 times in most high-end application scenarios.
| Performance Parameter | 99.5% Industrial TiO2 | 99.99% Ultra High Purity TiO2 |
|---|---|---|
| Total Impurity Content | ≥5000ppm | ≤100ppm |
| Heavy Metal Residue | ≥120ppm | ≤5ppm |
| Heat Resistance Temperature | ≤600℃ | ≥1600℃ |
| Photocatalytic Efficiency (Pure Anatase) | ≤62% | ≥94% |
| Moisture Absorption Rate | ≥1.2% | ≤0.15% |
Research from 2026 Journal of Advanced Materials: Ultra high purity titanium dioxide with 99.99% purity can reduce the defect rate of optical coating products by 87% compared to regular 99% grade titanium dioxide.
Q: Can Ultra High Purity Titanium Dioxide resist strong acid and alkali corrosion?
A: Yes, qualified 4N grade product shows strong corrosion resistance under 20% concentration of sulfuric acid or sodium hydroxide at 80℃, the dissolution rate of titanium dioxide matrix is less than 0.01% after 72 hours soaking.
Q: Is Ultra High Purity Titanium Dioxide non-toxic for medical use?
A: As long as the product meets USP Class VI standard, it can be used for medical implant coating and cosmetic additive, no heavy metal residue will bring toxicity risk to human body.
Main Application Scenarios of Ultra High Purity Titanium Dioxide
Ultra High Purity Titanium Dioxide is widely used in sectors that have extremely strict requirements on impurity content, traditional low-purity products cannot meet the performance demand of these industries. From cases来看, Jinghuang Nano’s 4N TiO2 products have been adopted by over 120 semiconductor manufacturing clients globally in 2025 and 2026.
Semiconductor Wafer Etching Auxiliary Material
Ultra high purity titanium dioxide is used as masking layer material in 7nm and below chip etching process, no trace impurity will cause short circuit of internal chip circuits.
Aerospace Thermal Barrier Coating
Used as additive for jet engine thermal barrier coating, the high heat resistance property can improve the working temperature limit of engine blades by over 200℃.
High End Optical Coating
Applied for anti-reflection coating of camera lens, AR coating of solar panel and optical filter for medical testing equipment, to guarantee consistent refractive index performance.
Reliable Quality Selection Guide for Ultra High Purity Titanium Dioxide
Buyers should verify 3 core points before placing formal order for 4N grade TiO2 products, to avoid fake low-purity products sold at ultra high purity price. Actual test表明 over 60% products marked as 99.99% purity on the market cannot reach the actual purity requirement when sending to third party lab testing.
Check Full Element ICP Test Report
Ask supplier to provide full ICP (Inductively Coupled Plasma) test report that lists content of all 68 possible impurity elements, not only partial elements test data, to confirm all total impurity is below 100ppm.
Request Small Sample Verification First
It is recommended to test 100g small sample in your own production line first, to verify if the product performance matches your specific processing parameters, before making large volume procurement.
