  Characteristic:White rhombic
  crystal of powder.The melting
  point is approximately 287℃.It
  is easily dissolved in the
  water,alcohol and acetone.The
  aqueous solution shows
  neutrality.It can produces blood-
  red ferric thiocyanate with
  molysite and does not react with
  ferrite.It produces yellow sodium
  thiocyanate with concentrated
  sulfuric acid and blue-black
  cobalt thiocyanate with cobalt
  salt .It produces mercuric silver
  salt nantokite.It is easily
  deliquesced in the air so it
  should be sealed for storage.
  Applications: General :Mainly
  used in sectors of
  pharmaceuticals
  pesticede,synthetic
  fiber ,electeroplating,phogography
  ,accelerator for cement etc
  Fiber industry:as spinning
  sovelent for polyacrylonitrile
  Architecture industry:hardening
  accelerator for cement and
  concrete mixes
  Pesticide:raw material for the
  production of a number of
  herbicides and fungicides
  Pharmaceuticals:raw material for
  the production of a number of
  pharmaceutical products
  Packing:25kg paper bags with
  polyethylene lining ,40 bags per
  pallet
  500kg big bags ,2bags per pallet
  Solution,in bulk tank-wagons or
