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.<\/p>\n
Properties<\/p>\n
Chemical Formula: SeS\u2082<\/p>\n
Molecular weight: 143.09<\/p>\n
Appearance: Orange-yellow to orange-red powder.<\/p>\n
Odor: characteristic odor of hydrogen sulfide.<\/p>\n
Solubility: insoluble in water, slightly soluble in chloroform, very slightly soluble in ether, soluble in organic solvents such as carbon disulfide.<\/p>\n
Density: about 2.54 g\/cm\u00b3.<\/p>\n
Melting point: decomposition begins at <100\u00b0C<\/p>\n
Stability: relatively stable at room temperature and pressure, but easily decomposed by heat or in moist air, producing toxic gases such as hydrogen selenide.<\/p>\n
Oxidizing property: It has certain oxidizing property, and can be used as oxidizing agent in some chemical reactions.<\/p>\n
Reaction with acid: It can react with strong oxidizing acid to produce corresponding selenium compounds and sulfur dioxide.<\/p>\n
Applications<\/p>\n
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.<\/p>\n
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.<\/p>\n
Glass industry: It can be used as decolorant in glass manufacturing to remove the green tint in glass and make glass more transparent.<\/p>\n
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.<\/p>\n","protected":false},"excerpt":{"rendered":"
