Product Details
Compared with rutile in crystal lattice structure, anatase features lower hardness and refractive index. Though inferior in thermodynamic stability, anatase can maintain a metastable state for a long time; it will undergo irreversible transformation into rutile when heated above 700°C. In terms of optical properties, anatase boasts higher transparency in the near-ultraviolet range.
Titanium(IV) oxide is extensively applied in UV-resistant fabrics, skin creams and cosmetic products. It also functions as a high-efficiency photocatalyst, being indispensable in self-cleaning glass, ceramics, air purification and chemical processes. Furthermore, it can enhance the opacity of paper, and it serves as a critical raw material for the production of titanium and alloy materials in the metallurgical industry.
