Key Properties
Strontium sulfide (SrS) is a highly reactive inorganic compound that serves as a significant reference material in the field of phosphor materials chemistry. With a purity of 99.9%, it is utilized in various applications, particularly in the development of phosphorescent materials. This compound is notable for its ability to release hydrogen sulfide (H2S) when it comes into contact with moisture or acids, making it essential to handle with care. Strontium sulfide is also recognized for its role in the production of strontium-based phosphors, which are critical in lighting and display technologies.
Also known as Strontium monosulfide.
