colloidal silicon dioxide

The rise of China's titanium dioxide importers can be attributed to several factors. Firstly, China's rapid industrialization and urbanization have resulted in a surge in construction projects, which require vast amounts of paint and other building materials containing TiO2. Additionally, the country's thriving manufacturing sector, particularly in the production of appliances, furniture, and automobiles, has further driven up the demand for titanium dioxide. As a result, Chinese importers have been scouring the globe for reliable suppliers capable of meeting their extensive requirements.

To address these challenges, researchers are exploring alternative production methods that are more energy-efficient and environmentally friendly. For example, the use of solar energy to power the oxidation of titanium ore has been proposed as a way to reduce the energy consumption of the sulfate process. Other approaches include the development of new catalysts that can replace sulfuric acid in the oxidation step, as well as the exploration of bio-based feedstocks for TiO2 production.

Below are selected applications of photocatalytic pollutant decomposition processes on titanium oxide:
1. Self-cleaning surfaces: for the production of glass for spotlights, traffic lights, car mirrors, window panes, for road paints, for covering sound-absorbing screens and tunnel walls.
2. Air cleaning and odor removal: filters that are used in enclosed spaces (e.g. public toilets) or filters for air-conditioning equipment.
3. Water treatment: groundwater treatment installations, water purification installations in the intakes of drinking water from rivers.
4. Self-disinfecting materials: towels, linings, clothing, equipment in hospitals, wall surfaces of operating rooms.
5. Removal of lesions: anti-cancer therapy.
