Silicon monoxide is the chemical compound with the formula SiO. When SiO gas is cooled rapidly it condenses to form a glassy brown/black amorphous solid which is available commercially and used to deposit films of SiO, which oxidize in air giving SiO2.
For a typical sample of SiO the refractive index and extinction coefficient at 632.8 nm are 1.96507 and 0.01056394. Below are files of complete refractive index and extinction coefficients. If the file is not available for download, you can request our proprietary file by clicking "Request".
