Product Overview

Silicon dioxide (SiO2) is one of the most abundant, structurally complex, and widely used inorganic materials on Earth. It has many forms, such as quartz crystal, amorphous silicon dioxide solid, silicon dioxide colloid and different kinds of aerogels. Generally, the silicon atoms in silicon dioxide molecules are tetrahedral coordinated, consisting of four oxygen atoms surrounding a central Si atom. In recent years, silica particles have shown significant value in the fields of materials chemistry and physics due to their adjustable size, morphology, microstructure, and easy surface functionalization. Particularly, silica particles functionalized with various functional groups have been widely used in catalysis, adsorption, sensing, and biomedical applications. The synthesis methods of silica particles include: sol gel method, lotion method, precipitation method and chemical vapor deposition method, among which the sol gel method is often used in the laboratory due to the high quality of silica particles. In the sol gel method, tetraethyl silicate (TEOS), tetramethyl silicate (TMOS) and polysiloxane are usually selected as the silicon source, ammonia is used as the catalyst, and is dispersed into a suitable solvent (alcohol or water) to form a solution. By controlling the pH value, the silicon source is hydrolyzed to obtain a sol system, and then aged to gel. Finally, the solvent is evaporated by heat treatment to obtain monodisperse silica nanoparticles, which is also referred to as the Stober method.

Application Fields

 

1. Controllable particle size: By adjusting reaction conditions such as reactant concentration, reaction time, temperature, etc., the size of silica particles can be accurately controlled.

2. Good monodispersity: The prepared solid silica particles have good monodispersity, that is, the particle size distribution is relatively uniform.

3. Adjustable surface properties: Its surface chemical properties can be changed through subsequent surface modifications to meet different application requirements. Such as amination (APTES modification) and carboxylation (succinic anhydride modification).


Product Features

 

1. Chromatographic packing: Due to its good monodispersity and chemical stability, it can be used as a stationary phase packing in high-performance liquid chromatography (HPLC) and gas chromatography (GC).

2. Optical materials: used for preparing optical coatings, anti reflective films, etc., to improve the performance of optical devices.

3. Coatings and Coatings: Enhance the wear resistance, corrosion resistance, and hardness of coatings and coatings.

4. Biomedical field: Surface modification of specific antibodies or ligands for the isolation of specific types of cells. It can also be combined with fluorescent dyes or quantum dots for imaging of cells and tissues.

Good, inexpensive work watch
Color: all black watch
Bought as a working watch so I don’t wreck my good watches. It’s been working just fine and holding up well while not taking very good care of it. Keeps accurate time. Glass has stayed clear. Black finish looks good and is holding up well. Seems to hold up with steady pounding. Stop watch buttons are a bit crude and will mess up your time when your hand gets pushed back against it during hard labor. However, I have not babied this watch at all.
