Titanium dioxide (TiO₂) is widely used across various industries for its brightness and opacity. However, growing health concerns have prompted discussions about removing it from products. This process is complicated, as TiO₂ plays a crucial role in product performance. Alternatives like calcium carbonate and zinc oxide exist but often come with trade-offs regarding effectiveness and cost. Industries must navigate these challenges while adhering to regulatory changes, particularly following the European Union’s ban on TiO₂ as a food additive due to safety concerns. Continuous research into innovative materials may provide safer substitutes that meet performance standards without compromising quality.

Titanium dioxide (TiO₂) plays a crucial role in ceramics by enhancing their aesthetic and functional properties. It amplifies color brilliance and opacity through its high refractive index, allowing for vibrant finishes and intricate patterns. Additionally, TiO₂ boosts mechanical strength by forming crystalline phases that improve durability and fracture resistance. Its ability to enhance thermal stability ensures that ceramics can withstand high temperatures without losing integrity. Furthermore, innovations like nano-TiO₂ are paving the way for advanced functionalities in ceramics, including electrical modifications and sustainability benefits through reduced energy consumption during firing. Overall, TiO₂ is an indispensable component in modern ceramic engineering, driving both aesthetic appeal and performance improvements.
