There are numerous harmful effects of silica gel, especially the form that contains cobalt chloride. Ingesting silica gel causes dehydration and discomfort since the main purpose of the product is to absorb water, but only if a lot is swallowed. Silica gel causes irritationGet A Quote
Organika Silica Gel Organika European standard Silica Gel from organic fossilized silica sources is made form diatom, a single cell plant species related to the Brown Algae pheophycious which grows in lakes and oceans. The diatom build their external skeleton from the silica present in the water.
As a solid foam stabilizer,spherical silica particles with diameters ranging from 150 to 190 nm were prepared via an improved Stber method and were subsequently modified using three different silane coupling agents to attain the optimum surface hydrophobicity of the particles. ...
2020-3-6Example Conditioning the silica gel to equilibrium moisture content at 50 RH. According to Appendix 2, 27.07 water EMC gg dry weight is needed in regular silica gel to be in equilibrium at 50 RH. If you start with 1000 g of dry silica gel, introduce water until the weight of the humid sorbent reaches 1270.7g 1000 x 1.2707.

Copper Cu2, cadmium Cd2 and lead ions Pb2 are toxic to human beings and other organisms. In this study, a silica gel material modified with nitrilotriacetic acid NTA-silica gel was sensibly designed and prepared via a simple amidation procedure for the removal of
Desiccant Silica Gel is an amorphous form of Silicon-di-oxide Silica Gel is an inorganic chemical. It function is to adsorb moisture from the air. Silica Gel is free from any toxic chemical, heavy metal, DMF, PCP. Silica Gel is free from any toxic chemical,heavy metal,DMF,PCP. Chemical Analysis Report for White Silica Gel
Silica, also called silicon dioxide, compound of the two most abundant elements in Earths crust, silicon and oxygen, SiO 2. The mass of Earths crust is 59 percent silica, the main constituent of more than 95 percent of the known rocks. Silica has three main crystalline varieties quartz by far the most abundant, tridymite, and cristobalite.
Silica, or silicon dioxide SiO2, is the same material found in quartz. The gel form contains millions of tiny pores that can adsorb and hold moisture. Silica gel is essentially porous sand. There is no significant difference in the chemical structure, it is all Silicone Dioxide.
