Silicon dioxide (SiO2) is a common fundamental constituent of glass. Fused quartz is a glass made from chemically pure silica. Silicon has a very similar structure to the Diamond structure found in Carbon, but Si—Si bonds are not as strong as C — C bonds, so Silicon is not as hard as Diamond. Silicone is not biodegradable because it is synthetic, and microorganisms cannot break it down. They do not recognize this material as food. It shares this characteristic with plastic, but unlike plastic, it doesn't break down into microplastics over time. We found that the deposition of oxygen-deficient metal oxides can decompose the SiO2 layer. The oxygen in the underlying SiO2 layer can be absorbed to form fully oxidized metal oxide films. Highly flammable. Insoluble in water. A significant dust explosion hazard. The flame retardant that contains Silicon decomposes into silicon dioxide (SiO2) when heated in an atmosphere of air, forming an inorganic protective layer on the substrate, isolating it from the source of the fire, and inhibiting exchanges of mass and energy. The evidence obtained from cultured cells and animals suggests that exposure to SiO2NPs can trigger neurotoxic effects and may be considered a risk factor facilitating neurological disorders' onset and progression. Silicon dioxide, or silica, is considered a trace mineral and is hypothesized to enable mineralization for bones, teeth, and collagen. Silicon dioxide has not been widely studied, so a daily required intake level is not established.
