Sodium silicate, chemical formula SiO2, dry environment demand with high efficiency at the micro-pores and the network system absorbing substances in the absorption. High capacity synthetic absorbant. It was discovered by Walter A. Patrick in 1900s. It can react in case of contact with air during storage. In daily life, it is a small package item that comes out of the newly received shoe box.
O Si O
Production and Reactions
The ammonium tetracene can be obtained by washing the cobalt and acidifying it and by appropriately interacting with COCl2.
It is used in industrial air drying systems by taking advantage of absorption feature.
Its most important feature is its use as a moisture retainer and it is preferred in many sectors.
It is common to use undesirable gases.
It is also used for the protection of foodstuffs.
It is used to protect electronic materials and their contents.
It is used as humidity holder in desiccators in laboratories.
