The Silicon Dioxide Food Additive use Silion dioxide is big of ratio surface accumulate, make its ability at of the grain of the powder material rise the partition of function, promoted the freedom of the powder material flow at the same time, its hygroscopicity power can also strengthenned the anti- agglomeration function and adsorptions biggest. Can used for planting the fat end(the milk crystal), fragrance extract, spice, the instant noodles soup to anticipate etc. To make the anti- agglomeration in the food.
Usage:
1.Silicon Rubber: Improves silicon rubbers durability, rebound rate, and anti-distortion performance.
2.Plastics Industry: Improves plastic s tenacity, strength and prevents water absorption.
3.Coating Industry: Prevents agglomeration and drip. Thixotropic additives. Increase denseness and smoothness of paint.
4.Medicine Industry: Increase denseness ,floating , carrying function in medicine. It also can be used as the pesticide powder and anti-agglomeration.

Details
The chemical compound Silicon Dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula SiO2. 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.
Silica is manufactured in several forms including fused quartz, crystal, fumed silica (or pyrogenic silica), colloidal silica, silica gel, and aerogel.
Silica is used primarily in the production of glass for windows, drinking glasses, beverage bottles, and many other uses. The majority of optical Fibers for telecommunications are also made from silica. It is a primary raw material for many whiteware ceramics such as earthenware, stoneware, porcelain, as well as industrial Portland cement.
Silica is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications. It is the primary component of diatomaceous earth which has many uses ranging from filtration to insect control. It is also the primary component of rice husk ash which is used, for example, in filtration and cement manufacturing.
Thin films of silica grown on silicon wafers via thermal oxidation methods can be quite beneficial in microelectronics, where they act as electric insulators with high chemical stability. In electrical applications, it can protect the silicon, store charge, block current, and even act as a controlled pathway to limit current flow.
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.
In its capacity as a refractory, it is useful in fiber form as a high-temperature thermal protection fabric. In cosmetics, it is useful for its light-diffusing properties and natural absorbency. Colloidal silica is used as a wine and juice fining agent. In pharmaceutical products, silica aids powder flow when tablets are formed. It is also used as a thermal enhancement compound in ground source heat pump industry.
