Introduction of Silicon dioxide
Silicon dioxide, also known as silica (from the Latin silex), is a chemical compound that is an oxide of silicon with the chemical formula SiO2. It has been known since ancient times. Silica is most commonly found in nature as quartz, as well as in various living organisms. Silica is one of the most complex and most abundant families of materials, existing both as several minerals and being produced synthetically. Notable examples include fused quartz, crystal, fumed silica, silica gel, and aerogels. Applications range from structural materials to microelectronics to components used in the food industry.
Silica has a unique capacity to absorb moisture. This property makes silica an excellent anticaking agent. Anticaking agents are used to prevent ingredients from sticking together and maintain even distribution of nutrients or active ingredients. This is important in ensuring the potency of the product meets the claims listed on the label.
