Silicon Monoxide CAS 10097-28-6

What is Silicon monoxide CAS 10097-28-6?

Silicon monoxide CAS 10097-28-6, also known as silicon(II) oxide, is produced commercially by reducing silicon dioxide with silicon, carbon, or hydrocarbons in hydrogen at approximately 1000°C to generate SiO vapor, which is then condensed and powdered for use; it does not occur naturally in significant quantities and has been employed in industrial applications since the mid-20th century, particularly in vacuum evaporation techniques for thin-film technologies.

Specifications

Features

• Nonstoichiometric Form: Designated as SiOx where x varies between 1 and 2, allowing compositional flexibility in deposition processes.
• Vapor Deposition: Deposited via physical vapor deposition methods, including sublimation from resistance-heated sources.
• Thin-Film Suitability: Evaporates readily in manufacturing setups, enabling uniform layer formation on substrates.
• Covalent Bonding: Exists as a covalently bonded unit, supporting stable integration in multilayer assemblies.
• High Purity Availability: Offered in ultra-high purity grades for specialized thin-film and coating demands.

Applications

• Optical Coatings: Used in IR and VIS multilayer coatings for reflectors, flood lamps, mirrors, and jewelry to minimize near-infrared reflection or create interference effects.
• Adhesion Promotion: Acts as an adhesion layer in visible and near-infrared spectral ranges for enhanced film bonding.
• Protective Layers: Forms thin surface films to shield aluminum coatings, optical components, dielectrics, and insulators.
• Electronic Components: Serves as dielectric, insulating, and protective layers in thin-film capacitors, hybrid circuits, and semiconductor devices.
• Decorative Finishes: Produces iridescent and colored metallically reflecting coatings, such as on sunglasses.
• Barrier Coatings: Applied as barrier layers on polymer films in web coating processes for packaging and flexible electronics.
• Ceramic Synthesis: Functions as a raw material for producing fine ceramics like silicon nitride and silicon carbide powders.
• Energy Storage: Investigated for roles in energy storage technologies due to distinctive electrical characteristics in optoelectronic contexts.
