4N (99.99%) Silicon Monoxide (SiO) Pieces (1-3mm) Evaporation Materials

Silicon monoxide (SiO) is the chemical compound where silicon is present in the oxidation state +2. In the vapor phase, it is a diatomic molecule. It has been detected in stellar objects and has been described as the most common oxide of silicon in the universe. It has been widely used as surface coatings, insulating layers in integrated circuits, dielectric material in capacitors and anode materials for Li-ion batteries. 

The dimensions and purities can be customized upon request. Please contact us for customization or bulk orders
