Silicon monoxide（Cat No.:M062743）, is a chemical compound consisting of silicon and oxygen in a 1:1 ratio. It is typically found as a dark brown to black amorphous powder or as a solid mass. SiO is an intermediate in the production of silicon dioxide (SiO₂), commonly known as silica, which is a critical material in glassmaking, ceramics, and the semiconductor industry. Silicon monoxide is used primarily in thin film coatings and in the manufacturing of optical components due to its ability to form layers with controlled refractive indices, enhancing the properties of optical and electronic devices. Additionally, its unique composition is of interest in materials science research, especially for its applications in microelectronics and protective coatings.
