FAQ

What are the physical and chemical properties of Silicon monoxide (CAS: 10097-28-6)?

Silicon monoxide (CAS: 10097-28-6) is a white amorphous solid with a molecular weight of approximately 62.99 g/mol. It has a low solubility in water but is highly reactive with moisture and oxygen. It is used in semiconductor applications and has a crystalline form under vacuum conditions.

How is silicon monoxide (CAS: 10097-28-6) typically synthesized?

Silicon monoxide is typically synthesized through the reduction of silicon dioxide with carbon at high temperatures. Other methods include the thermal decomposition of silicon tetrafluoride or silicon trifluoride in the presence of oxygen or fluorine. The yield and selectivity depend on the reaction conditions and catalysts used.

What industries use silicon monoxide (CAS: 10097-28-6)?

Silicon monoxide finds applications in various industries, particularly in the semiconductor industry for doping silicon wafers. It is also used in the production of silicon carbide (SiC) and in some sensing technologies due to its unique electronic properties.

What precautions should be taken when handling silicon monoxide (CAS: 10097-28-6)?

Handling silicon monoxide requires caution due to its reactivity with water and oxygen. Personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. Work should be conducted in a fume hood, and proper spill management procedures should be followed. Refer to the Safety Data Sheet (SDS) for detailed information on handling and disposal.
