Description : Blue-green crystal or granule, odourless,
density:1.898g/cm3, melting point: 64℃, soluble in
water(solubility: 0.486g/mL at 50℃). It will be
decomposed into corrosive Fe2O3 when heated. It is
efflorescent in dry air and oxidized in wet air.
Features : In industry, it is used to produce the ferric salt, ink,
ferric oxide and indigo-blue. Also, it is applicated as the
dye mordant, tanning agent, water purification agent,
preservative of wood and disinfectant. In agriculture, it
is used as fertilizer, weedicide and pesticide to tackle
the dustbrand of wheat.
