Product Overview
This 99.99% pure titanium(IV) oxide in rutile crystalline form represents the highest commercially available grade for demanding laboratory and industrial applications. The rutile modification offers superior thermal stability up to 1800°C, making it ideal for high-temperature processes. Its exceptional refractive index (2.76) and UV absorption properties enable advanced optical applications. The material exhibits outstanding photocatalytic activity under UV light, with a bandgap of 3.0 eV that facilitates efficient electron-hole pair generation. The powder form ensures uniform dispersion in various matrices while maintaining chemical inertness in most environments. With a density of 4.23 g/cm³ and Mohs hardness of 6.5, this titanium dioxide provides excellent abrasion resistance. The ultra-high purity minimizes trace metal contaminants that could interfere with sensitive reactions or measurements. The material’s dielectric constant of 114 makes it valuable for electronic applications requiring high permittivity materials. All batches undergo rigorous ICP-OES analysis to verify the 99.99% metals basis purity specification.
FAQs
1. What is the difference between rutile and anatase titanium dioxide forms?
Rutile TiO2 has higher density, refractive index, and thermal stability compared to anatase. It also shows different photocatalytic properties with a narrower bandgap (3.0 eV vs 3.2 eV for anatase), making it more efficient for certain UV-driven reactions while being more stable at high temperatures.
2. Can this titanium dioxide be used for food or cosmetic applications?
This 99.99% pure grade is specifically produced for laboratory and industrial applications. For food or cosmetic use, you would need titanium dioxide that meets specific regulatory standards like USP or FCC grades, which include additional purity and safety certifications.
3. What is the typical particle size distribution for this rutile TiO2?
The powder typically exhibits a particle size range of 0.2-0.5 microns with a narrow distribution. The primary particle size is around 0.3 microns, though some agglomeration may occur which can be dispersed through proper mixing techniques.
4. How should this high-purity titanium dioxide be stored to maintain its properties?
Store in a tightly sealed container in a cool, dry environment away from direct sunlight. While chemically stable, exposure to moisture can lead to agglomeration over time. For long-term storage, consider using desiccants in the storage container.
5. What analytical methods are used to verify the 99.99% purity specification?
The purity is verified through inductively coupled plasma optical emission spectroscopy (ICP-OES) for metal impurities, with additional confirmation via X-ray diffraction (XRD) to ensure proper crystalline phase and absence of other titanium dioxide polymorphs.
