Selenium Disulfide Powder is an orange-yellow to orange-red, hydrogen sulfide odor, insoluble in water, molecular weight 143.09 powder, which has different applications in pharmaceutical, rubber, glass and other industries.
Properties
Chemical Formula: SeS₂
Molecular weight: 143.09
Appearance: Orange-yellow to orange-red powder.
Odor: characteristic odor of hydrogen sulfide.
Solubility: insoluble in water, slightly soluble in chloroform, very slightly soluble in ether, soluble in organic solvents such as carbon disulfide.
Density: about 2.54 g/cm³.
Melting point: decomposition begins at <100°C
Stability: relatively stable at room temperature and pressure, but easily decomposed by heat or in moist air, producing toxic gases such as hydrogen selenide.
Oxidizing property: It has certain oxidizing property, and can be used as oxidizing agent in some chemical reactions.
Reaction with acid: It can react with strong oxidizing acid to produce corresponding selenium compounds and sulfur dioxide.
Applications
Pharmaceutical field: Selenium Disulfide is a common antifungal drug ingredient, commonly used in the treatment of dandruff, seborrheic dermatitis and other skin diseases, with anti-seborrhea, anti-fungal, keratolytic and other effects.
Rubber industry: Selenium Disulfide can be used as vulcanizing agent of rubber, which can improve the performance of rubber such as abrasion resistance, aging resistance and mechanical strength.
Glass industry: It can be used as decolorant in glass manufacturing to remove the green tint in glass and make glass more transparent.
Other fields: Selenium Disulfide can also be used in electronics, optics and other fields, such as as a dopant for semiconductor materials, but these applications are relatively few.
