SILICON MONOXIDE POWDER
TECHNICAL DATA
PROPERTIES
Silicon monoxide is an amorphous solid which does’t have a characteristic X-ray diffraction pattern. SiO is brown in powder and black in granular.
It is stable at room temperature, but at temperatures of 400-800°C, X-ray readings show traces of the disproportionation products silicon and quartz.
APPLICATION
Optical SiO coatings are used for optical applications in reflectors, flood lamps, mirrors, jewelry, and other products. SiO coatings can reduce reflection in the near infrared range or act as interference layers. SiO is also ideal for use with ZnS and other materials for reflective coatings.
Electronic SiO films are used in thin-film capacitors, hybrid circuits, semiconductor components, and other electronic applications. A variety of insulating and dielectric properties can be achieved by proper selection of SiO film thickness.
Protective SiO films are deposited on aluminum surface mirrors, lenses and gratings to protect against corrosion and wear.
