Silicon monoxide preparation
1. After silicon dioxide has reacted with elemental silicon, rapid cooling is required to make silicon monoxide.
Silicon monoxide The material is not stable. It will be oxidized into silicon dioxide in air and is only stable when temperatures are above 1200degC.
Avoid open flames and high temperatures. It is insoluble with water and soluble with a mix acid of dilute hydrofluoric acids and nitric Acid. Heat and electricity are well insulated by this material. It is oxidized in air and forms a silicon oxide film. In oxygen, it burns and then reacts with the water to form hydrogen. In the warm alkaline solution, hydrogen is produced and silicate is dissolved.
Silicon monoxide use
A fine powder of silicon monoxide can be used to synthesize fine ceramics due to its high activity. This includes silicon nitride or silicon carbide. Useful in the preparation optical glass and semiconductors.
As a protective layer, vaporize it and apply it to the mirror surfaces of optical instruments. Preparation semiconductor materials.
Silicomonoxide and its hazards
In the event of eye contact, rinse with lots of water immediately and take to a doctor.
Wear protective clothing.
Eyes, skin, and respiratory tract are all affected.
Most water bodies are only mildly affected by this substance. Do not allow large quantities of undiluted products to enter groundwater, waterways or sewage system.
Stable at normal temperatures and pressure. Avoid light, open flames and high temperature.
Place in a ventilated, dry and airtight place.
Inhalation – If the patient inhales, it is best to move them to fresh air.
Skin contact: Remove all contaminated clothing. Wash your skin with soap and warm water. Seek medical attention if you feel unwell.
Eye contact: Separate eyelids, and rinse them with normal saline. Seek medical attention immediately.
Ingestion: Rinse the mouth and prevent vomiting. Seek medical attention immediately.
Advice for protecting rescuers – Move the patient into a safe area. Consult with a doctor. The doctor should see this sheet of chemical safety information.
