MP EcoChrom™ SILICA is used as a suspending and thickening agent in pharmaceutical.A silica-based aerogel was used in the Stardust spacecraft to collect extraterrestrial particles. Silica is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. SiO2 has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. In the majority of silicates, the Si atom shows tetrahedral coordination, with 4 oxygen atoms surrounding a central Si atom.

MP EcoChrom™ Silica, the chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula SiO2 with a mean pore size of 60Å and particles size of 200-500μm. MP silica are free of particles outside the standard range. The irregular shape of MP Silica permits the easy packing of column permeability and plate number. They allow easy switching from one sieve cut to another, offering an easy way to change the chromatographic methods. It has been known for its hardness since ancient times. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.
