Application in ceramics
Researchers have added an appropriate amount of nano-SiO2 to ceramic products, which not only greatly reduces the brittleness of ceramic products, but also increases their toughness several times or even dozens of times, and the finish is also significantly improved. The ceramics are also fired at lower temperatures. So that the grade of ceramic products is improved by several orders.

Application in plastic field
Conventional SiO2 is added to plastics as a reinforcing agent to improve the performance of plastics. The role of nano-SiO2 is not only for reinforcement, it also has many new properties. This is mainly by using nano-SiO2 to transmit light and have a small particle size. Plastic becomes denser. Adding nano-SiO2 to the polystyrene plastic film can improve its transparency, strength, and toughness, and also improve the water resistance and aging resistance accordingly. The performance index of nano-SiO2 modified polyvinyl chloride waterproofing membrane has reached or exceeded the EPDM waterproofing membrane.

Application in rubber field
The new rubber added with nano-SiO2 not only has superior mechanical properties, but also can be designed with special new rubber according to needs. The nano-SiO2 in this new material not only has a reinforcing effect, but also has some functional characteristics that conventional rubber does not have. In addition, nano-SiO2 can be used to modify the tire side rubber to produce color tires.

4
Application in coatings
Nano-SiO2 has extremely strong ultraviolet and infrared reflection characteristics. Therefore, when added to the coating, it can form a shielding effect on the coating, thereby achieving the purpose of resisting ultraviolet aging and heat aging, and at the same time, increasing the thermal insulation of the coating. In addition, nano-SiO2 also has a three-dimensional network structure, has a large specific surface area, shows great activity, can form a network structure when the coating is dried, not only increases the strength and finish of the coating, but also maintains the color of the coating Long-term unchanged.

Application in textile field
The composite powder with proper proportion of nano-SiO2 and nano-TiO2 is an important additive for anti-ultraviolet radiation fibers. Nano-SiO2 and nano-TiO2 are mixed into chemical fibers, and the obtained chemical fibers have functions of deodorizing and purifying air.

Application in other fields
In agriculture, the application of nano-SiO2 to produce agricultural seed treatment agents can increase the yield of vegetables (cabbage, tomato, cucumber), cotton, corn, and wheat, and advance the maturity period. In addition, nano-SiO2 has high surface energy and adsorption properties, has good stability and biological affinity, and can be used as a new type of sensor. The use of nano-SiO2 modified sunscreen to block 99% of ultraviolet light has completely replaced the organic ultraviolet light absorber previously used in sunscreen products.

In addition, it also has important applications in electronic assembly materials, sealants, adhesives, functional fibers, wood and environmentally friendly adsorption.
