Product Name:Ammonium pentasulfide
English Name:Ammonium pentasulfide
CAS No.:12135-77-2
Aliases:Tetraammonium decasulfide, Ammonium sulfide
Molecular Formula:(NH4)2S5
Physical Properties:Yellow crystalline powder with a hydrogen sulfide odor. Melting point approximately 50°C (decomposes), density 1.31 g/cm³. Soluble in water, slightly soluble in ethanol, insoluble in diethyl ether. Hygroscopic and decomposes in air, releasing hydrogen sulfide gas. Strong reducing agent; decomposes upon contact with acids to produce hydrogen sulfide and sulfur.
Uses:Primarily used as a sulfidizing and flotation agent in ore smelting to facilitate the separation of metal sulfides. In the paper industry, it serves as a cooking auxiliary to promote lignin removal. In decorative building materials, it is applied as a coloring agent and surface treatment chemical for stone dyeing and concrete modification.
Technical Specifications:
Content ≥85%
Moisture ≤7%
Net weight 40kg ± 0.4kg
Executive standard HG/T2784-2012
Appearance: yellow crystalline powder
