What is Nano Silica? Silicon Dioxide Nanoparticles also known by silica nanoparticles and nano-silica appear as white powder.
P-type silica particles are divided according to the structure of nanometers. P-type silica particles have more nanopores than S-type, which has a porosity 0.61 mL/g and higher UV reflectivity. They also have a very small surface area.
Nano silica features a light volume, fluffy bulk density, less than 0.15-0.2g/cm3, an area specific of over 500m2/g, high chemical activity, and a large surface area.
The surface of nano silica contains an OH bond. This makes it a silicate group type of acid oxide. The water absorption rate is greater than 5 times that of silicate acid.
Silica nanoparticles have many uses. They are used as additives in rubber and plastic production, reinforced fillers for concrete, and as a stable platform for biomedical purposes such as drug delivery or therapeutic diagnostics.

What is Silica?
Silicon (or simply silicon) is one of the many chemical elements found in the earth’s crust. Its oxide forms, silicate (SiO4) or silicon dioxide (silica and SiO2) are its two forms.
It is common to use silicon in industry. The oxide form of silicon is often used in biomedical and industrial applications. SiNPs are rare because of their unique properties. These include ease of synthesis and surface modification, strong mechanical property, and relatively inert chemical structure. SiNPs have been used in biological materials for many decades.
Silica can be found in two forms, crystalline and amorphous. Although they share the same molecular structure, these two basic forms of silica have very different structural arrangements. Crystalline silica features a regular lattice arrangement while amorphous is more irregular. There are many forms of crystalline silica. Alpha-quartz is the most well-known, and can be transformed by heating to b-quartz or squamous silica. Porosils are porous crystalline silicon, which is also known as porous silica. All porosils come from synthetic materials.
Because of their rare properties (high surface area, large pores volume, adjustable size and chemical and thermal stability) and other unique characteristics, mesoporous silica and silica particles make excellent candidates for controlled drug releases. Amorphous silicon can be classified into three groups: natural forms and byproducts of power stations or metallurgical processes. Because of its biocompatibility with other elements and stability, amorphous silica has been considered a promising molecular imaging candidate and gene carrier. It is used in dental fillers, dental implants, dietary supplements and catheters.

What uses is nanosilica?
Nano silica can be used to modify cement concrete’s dispersion, plasticity, and thus increase its impermeability, enhanced permeability, frost resistance and reduce hydration heat. It also prolongs the service life.
It can be used as a vitrification agent, strengthening agent, adhesive, and glue of ceramics, enamels and glazes. It is also used as a high thermal binder in engineering-grade and refractories.
Use nanocomposite materials modifier as an inorganic adhesive at high temperature. Also used as an additive for inorganic compound materials. Used for strengthening, molding and filling of rubber/polymer material. Additionally, it can be used in a variety of resin engineering material; High-quality FRP packing that is corrosion-resistant.
Used for cement seals of oil wells and as reinforcement material under-ground engineering.
Use for special purposes, including lamp paint, lubricating oil, thickener or steel dehydrogenate and inner wall paint sensitive material. For solar cells and power cell energy storage.

Is nano-silica toxic?
Exposed to silica, particularly crystalline, has been extensively researched.
Studies have shown that occupational exposures to crystalline silicona can lead to silicosis in workers. This is a fibrotic lung condition that is often associated with lung cancers, emphysema, or tuberculosis.
Amorphous silica used to be considered less toxic than crystalline. Recent research has shown that SNPs that are amorphous have a potential for toxicity that is similar to that of crystallized particles. SiNPs’ physicochemical and crystallinity also produce different levels of toxicity in vitro as well as in vivo. Consider safety and possible adverse effects, especially those that may affect the immune system.
