- Functional Ceramics:
- Sensors, capacitive ceramics, thermistors, pressure-sensitive resistor ceramics, etc.
- Photocatalysts:
- Under UV light, forms electron-hole pairs, and reacts with O2 and H2O on its surface to generate hydroxyl radicals, oxidizing and decomposing organic compounds into water and carbon dioxide, thereby reducing or eliminating their harmful effects. Initial sulfur, phosphorus, and nitrogen atoms in organic compounds are converted into inorganic salts such as SO42-, PO43-, and NO3-.
- Plastics, การเคลือบ, Fibers:
- Utilized for UV radiation protection by scattering light, preventing UVA or UVB damage. Transparent, non-toxic, and efficient, suitable for sunscreen cosmetics, UV-resistant fibers, exterior wall coatings, plastic films, etc. Used in the paint industry as a white pigment and glaze for ceramics. Also employed in the paper industry as coatings and fillers to enhance the printability and opacity of paper.
- Metallurgical Industry:
- Used for the production of sponge titanium, titanium iron alloys, โลหะผสมแข็ง, etc. Also utilized in the manufacture of insulators, welding rods, and enamel.
- Synthetic Rubber, Printing, Dyeing:
- Additionally used in synthetic rubber, printing, dyeing, cosmetics, pharmaceutical fillers, and food additives.
- Paint Industry:
- Utilized as coatings and fillers in the paper industry to enhance printability and opacity of paper.
