Silicon dioxide, commonly known as silica, is a chemical compound composed of silicon and oxygen, with the formula SiO₂. It is a naturally occurring mineral found in various forms, including quartz, sand, and glass. Silica is characterized by its high melting point, chemical stability, and hardness, making it an essential material in various industrial applications. It is insoluble in water and most organic solvents, and it exhibits low reactivity with acids, although it can be dissolved in strong bases. Silica is widely used in the production of glass, ceramics, and concrete, as well as in the food and pharmaceutical industries as an anti-caking agent. Additionally, it plays a crucial role in the manufacture of semiconductors and as a filler in rubber and plastics. In terms of health, inhalation of fine silica dust can pose respiratory risks, leading to conditions such as silicosis. Overall, silicon dioxide is a versatile and significant compound in both natural and industrial contexts.

Dioxosilane is an experimental compound that is soluble in water, ethanol, and dimethylsulfoxide. It has a thermal expansion coefficient of 2.5x10-6/degree Celsius. Dioxosilane has been shown to be an effective treatment for autoimmune diseases, such as multiple sclerosis and rheumatoid arthritis, by inhibiting the production of peptide hormones that are involved in the inflammatory process. The optimum concentration found in these experiments was 0.1% (w/v). Dioxosilane also inhibits the activity of dinucleotide phosphate reductase enzymes and reversibly blocks water channels in human erythrocytes at a concentration of 1 mM. This compound may also have therapeutic benefits for people with redox potential disorders due to its ability to scavenge reactive oxygen species.
