Ammonium chloride, NH4Cl
Grade: industrial grade
Molecular formula: NH4Cl
Physical appearance: white crystal powder or granule; odorless, taste with salt and cool. Easy agglomerating after moisture absorption, soluble in water, glycerol and ammonia, is insoluble in ethanol, acetone and ethyl, it distillates at 350 and was weak acid in aqueous solution. Of ferrous metals and other metals are corrosive, in particular, greater corrosion of copper, non-corrosive effect of pig iron.
Purity(NH4Cl): 99.5%
Quality Assurance: People's Republic of China national standard: GB-2946-82
Main use: Mainly used in mineral processing and tanning, agricultural fertilizers. It is Auxiliaries for dyeing, electroplating bath additives, metal welding co-solvent. Also used in making tin and zinc, medicine, system of candles, adhesives, chromizing, precision casting and manufacture of dry cells, batteries and other ammonium salts.
Packing: Plastic woven bag internal with plastic bag, Neutral packing
Net weight: 25kg or 50kg per bag
