Silicon Monoxide

Silicon monoxide is widely used as a thin-film coating material to provide protective layers on mirrors and to create interference filters due to its stable refractive index.

It is a common source material for vacuum evaporation processes to deposit dielectric layers and moisture barriers on various substrates.

Silicon monoxide is utilized as a high-capacity anode material in lithium-ion batteries, offering a balance between high theoretical capacity and better structural stability compared to pure silicon.

Silicon monoxide targets are used in reactive and non-reactive sputtering processes to create thin insulating or passivating films in microelectronics.
