Crystal form: Rutile type (default, 100% phase-pure) or Anatase type (optional, high photocatalytic activity)
Particle size: 0.3–0.7 microns (typically 0.4–0.6 μm, customizable range 0.2–1.0 μm)
Specific surface area: 15–35 m²/g
Purity: >99% (metal impurities <0.1%, sulfur/phosphorus, etc. <10 ppm)
Morphology: Regular polygonal particles / quasi-spherical (uniformly dispersed, no obvious agglomeration)
Customizable: Surface modification (e.g., silane/aluminate coupling agent coating to improve compatibility), composite functions (e.g., blended with zinc oxide to balance sun protection and stability), specific particle size distribution (narrow distribution to optimize processing performance)
Quality control parameters: Crystal form (X-ray diffraction XRD), particle size (laser particle sizer / transmission electron microscopy TEM), specific surface area (BET method), purity (chemical titration / ICP analysis), UV shielding rate (UV-Vis spectrophotometer), photocatalytic activity (methyl orange degradation test)
