General description
The refractive index of silica nanoparticles is similar to polymeric coatings, so it finds several applications in the preparations of nanocomposites. Properties suh as, thermal resistance, electrical and mechanical are enhanced. Silica nanoparticles find uses in various fields of catalysts, pigment stabilization, electronics and sensors.
We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives. This is an enabling product and can be used as an alternative anode in lithium ion batteries due to its high energy storage capacity, low working potential, and abundance, offering a greener, potentially more sustainable option for energy storage.

Application
Silica nanoparticles have been used :
- To study the nonlinear optical properties of SiO2 nanocomposites in weak optical fields.
- As a nanoadditive in nanocomposite calcium alginate fibers.
- As dispersant in liquid polymethylsiloxane to exihibit unique optical non linearity in low intensity visible radiation fields.
