Brief Introduction
Silica is another name for the chemical compound composed of silicon and oxygen with the chemical formula SiO2, or silicon dioxide. There are many forms of silica. All silica forms are identical in chemical composition, but have different atom arrangements. Silica compounds can be divided into two groups, crystalline (or c-silica) and amorphous silica (a-silica or non-crystalline silica). c-Silica compounds have structures with repeating patterns of silicon and oxygen. a-Silica chemical structures are more randomly linked when compared to c-silica. All forms of silica are odorless solids composed of silicon and oxygen atoms. Silica particles become suspended in air and form non-explosive dusts. Silica may combine with other metallic elements and oxides to form silicates.

Brief Introduction
Selenium dioxide is mainly defined as oxidation reagent in organic synthesis, and it participates in many oxidation reactions. Due to the toxicity of the reagent, many reactions have been gradually replaced by other better reagents in recent years. However, the oxidation of selenium dioxide with active methyl, methylene and methylene still plays an important role in the conversion of organic chemical functional groups.
