Chemical Name: Silicon Dioxide
CAS Number: 112945-52-5
It is a volatile chemical substance with a very low density. Since it has hydrophilic properties, it has the ability to absorb water from the environment it is in.
Fumed silica is a powder consisting of amorphous silica spheres with a particle size smaller than microns.
Physical and Chemical Properties:
In terms of physical appearance, its non-crystalline form is transparent or gray. It has an amorphous powder appearance. It has no odor.
Its particle size is submicroscopic fumed silica.
Its melting point is over 1600 ° C.
In terms of solubility, it is generally insoluble in organic solvents and acids. However, due to its structure, it dissolves in hydrofluoric acid. It also dissolves in the presence of hot alkali hydroxide, that is, in hot sodium hydroxide.
Aerosil 200 is approximately 150 mg/L in water at 258 °C. However, the pH level should be approximately 7 in this process.
Aerosil 200 Usage Areas:
It is used to fill tablets and capsules in pharmaceutical applications due to its low particle size and large surface area. The purpose of use in these applications is to regulate the habits of dry powders.
Silicon dioxide in colloidal structure is used to stabilize some chemical mixtures. It is also used to thicken and suspend gels and semi-solid preparations.
It is a very good thixotropy agent.
It is used to prevent clumping and increase fluidity in disposable tea packages.
Fumed silica is added to epoxy binder systems. In this way, moisture problems that may arise during the hardening of the epoxy are eliminated.
Colloidal silicon dioxide can be used as a tablet disintegrant. It is used as an adsorbent dispersant in some application areas.
It is an important component of silicone rubber products. Therefore, when Fumed Silica is added to polymers, it provides an interface between the solid phase and a soft phase.
During the sucking of the calf from milk fans, bacterial infections occur in the animal's udders. Due to this problem, it needs to be disinfected. Silicon Dioxide is used for this.
Silicon dioxide can be used as a thickening agent during the production of hair curling medicine.
Silicon dioxide is used as an anti-sagging agent. In addition, it is used to prevent sedimentation.
Silicon is used in solar cells. The silicones in these areas have their own characteristics. Therefore, silicon specific to solar cells is produced. In this production, there is an oven using an arc reactor. In this oven, reduction is made with active carbon.
It is used in the production of some adhesives and sealants.
Fumed Silica is used as an anti-caking agent in toothpaste production. It is used in the formulation of paint remover products to ensure good adhesion on paint surfaces. In this way, viscosity is increased.
Other Areas of Use of Aerosil 200:
