What is Silicon Monoxide? ? Silicon monoxide The chemical formula for SiO is an inorganic substance. It is an amorphous black-brown powder that turns yellowish under normal temperatures and pressure. It has a melting and boiling point of 1802degC respectively. The density of the powder is 2.13g/cm3. It is hardly water soluble and can dissolve in the mixture of dilute acid hydrofluoric with nitric and release silicon tetrafluoride. When heated in air, this produces white silica. The silicon monoxide in the air will oxidize and become silicon dioxide. When the silicon monoxide vapour is slowly condensed (see disproportionation reactions), it will disproportionate into silicon and silica dioxide.
Silicon monoxide preparation
1. After silicon dioxide has reacted with elemental silicon, rapid cooling is required to make silicon monoxide.
SiO2 + S – 2SiO.
2. The silicon dioxide powder is mixed with coal tar powder and silicon dioxide with 99.5% SiO2 content. The C/SiO2 molar mixing ratio is 2.0. This mixture is heated to 1600°C under reduced pressure.
SiO2+C-SiO+CO.


Property and stability properties of silicon monoxide
Silicon monoxide The material is unstable, as it will oxidize into silicon dioxide in air. It only remains stable at temperatures over 1200degC.
Avoid open flames and high temperatures. It is insoluble with water and soluble with a mix acid of hydrofluoric acid dilute and nitric. 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 produce 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, evaporate the material in a vacuum. Preparation semiconductor materials.

Silicomonoxide safety precautions
If you come into contact with your eyes, immediately rinse them with lots of water. Then consult 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.
Avoid light, open flames and high temperatures.
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 your mouth with water and do not vomit. Seek medical attention immediately.
Advice to help protect rescuers – Move the patient into a safe area. Consult with a doctor. The doctor should see this sheet of chemical safety information.
