| Food | Employed as a food additive for coloring and whitening | Added to food products after rigorous purification to comply with food safety standards |
| Optical Glass | Serves as a raw material for optical glass manufacturing to increase refractive index | Melted with other oxides, formed into shape, and subsequently annealed |
| Ceramics | Used as a component in glazes to enhance surface gloss and durability | Mixed with other ceramic raw materials, applied to the green body surface, and fired at high temperature |
| Water Treatment | Acts as a photocatalyst for degradation of organic pollutants | Leverages the photocatalytic activity of titanium dioxide under UV irradiation to decompose organic compounds in water |
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Primary Component Content (TiO₂) | Ammonium Iron(III) Sulfate Titration | The sample is dissolved and Ti⁴⁺ is reduced to Ti³⁺ using metallic aluminum or zinc. The resulting Ti³⁺ is then titrated with ammonium iron(III) sulfate standard solution to determine the TiO₂ content. This method offers high accuracy and is suitable for high-purity products. |
| Spectrophotometry | Ti⁴⁺ forms a yellow complex with hydrogen peroxide under acidic conditions. Absorbance is measured at around 410 nm, and concentration is determined via a calibration curve. Suitable for trace or low-level detection. | |
| Impurity Element Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | After acid digestion or fusion, the sample is introduced into an ICP source for excitation. Impurity elements (e.g., Fe, Cr, Si, Al) are quantified based on the intensity of their characteristic emission lines. Enables simultaneous multi-element analysis with high sensitivity. |
| Atomic Absorption Spectroscopy (AAS) | For specific impurity elements (e.g., Fe, Pb, Cr), the sample is atomized in a flame or graphite furnace, and absorbance at specific wavelengths is measured for quantification. Simple to operate with good selectivity. | |
| Crystal Structure | X-Ray Diffraction (XRD) | X-rays are directed at the sample, and the diffraction pattern (peak positions and intensities) is analyzed to determine the ratio of rutile to anatase phases and assess crystalline purity. |
| Particle Size Distribution | Laser Particle Size Analysis | The sample is dispersed in liquid or gas, and particle size distribution is determined by analyzing angular scattering patterns of laser light. Fast and highly reproducible. |
| Scanning Electron Microscopy (SEM) + Image Analysis | Particle morphology is observed using SEM, and image processing software is used to statistically analyze particle size and distribution. Ideal for microscopic morphological and dimensional evaluation. | |
| Specific Surface Area | Nitrogen Adsorption Method (BET Method) | Nitrogen adsorption on the sample surface is measured at low temperature, and the BET equation is used to calculate specific surface area. Widely used for evaluating photocatalytic performance indicators. |
| Whiteness | Whiteness Meter Measurement | An integrating sphere-type whiteness meter measures tristimulus values under D65 illumination, and calculates whiteness indices (e.g., Hunter whiteness or Ganz whiteness) to evaluate appearance quality. |
| Moisture Content | Karl Fischer Titration | Quantitative determination based on the reaction of iodine and sulfur dioxide with water in anhydrous methanol. Available in volumetric and coulometric modes; suitable for trace moisture analysis. |
| Loss on Drying (LOD) | The sample is dried to constant weight at a specified temperature (e.g., 105–110°C), and moisture plus volatile content is estimated from mass loss. Simple to perform, but may include other volatiles. | |
| pH Value | pH Meter Measurement | A 10% aqueous suspension of titanium oxide is stirred thoroughly and the pH is directly measured using a calibrated pH meter, reflecting surface chemical properties. |
| Color Parameters (L*, a*, b*) | Colorimeter Measurement | Under standard lighting conditions, the lightness (L*), red-green value (a*), and yellow-blue value (b*) are measured to ensure color consistency in quality control. |
