Nanotechnology is rapidly sweeping via all significant domains of technology and science. Some of the technologies that make use of the Nanoparticles include dental, electronic, medical, defense and aerospace. This involves in synthesis, design, characterization, devices on Nanometer scale, applications of material and many more. At the nanoscale, the chemical, biological and physical properties vary from the features of molecules and atoms of bulk substances.

Different Facets of Silica Nanoparticles

Advancement of nanotechnologies has resulted in the mass production of Nanoscaled Silica particles. These are widely used in engineering composite as filler. You can extract these silica particles from the natural resources comprises metal impurities. The manufacturers of the silica Nanoparticles use various methods to produce these particles that are classified into two main approaches such as bottom up and top down approach.

The top down approach is described by decreasing original sizes with the use of physical approach such as special size reduction techniques. Chemical or bottom up approaches used a common route to produce the silica Nanoparticles from molecular or atomic scale. The commonly used methods for silica syntheses include flame synthesis, reverse Microemulsion and sol- gel process.

Silica test methods and features: Nano scale Silica particles are available with excellent features such as large surface areas, Small particle size, porous and narrow particle size distribution. On its surface, this particular particle consists of a large number of hydroxyl groups and also unsaturated residual bonds. This will shows high reflectivity to ultraviolet rays, long waves and visible light. The Nanoscale silica particles are tested by BET; usually it has large surface areas.

There exists large number of hydroxyl groups on its surface through infrared spectroscopy methods. Then it will form the silicon oxide structure which is in steady state. The features that showing high reflective to the UV rays and visible light proven by the Cary-5E spectrophotometer test.
