water,decompositing when heated,being complex with a lot of metals and
inorganic salts.
Use:
Used as thiazole medecine such as
sulphathiazole,tetramizole,thiourea dioxide and a medium of medicine curing
thyroid gland.Intextile industry,it's used as a bleaching agent,dyeing agent
and antioxidant.In the proeess of making a blueprint paper,it is characterized
by distinctness and fadelessness.In photo industry,it'used as a stabilizer of
developing emulsion and fixing bath.In the proeess of extracting gold, it can
replace the intense poison cyanide.Incopperplating and galanizing barium,it can
devide equally the deposition of matals,improve the stability of electroplating
solutiom and gain the lustre surface on the plating material. It's also used to
clean accumulated filty in the high-pressure boiler and as a synergist for
nitrogenous fertilizer.It can cure the mildew of oranges and tangerines and
tangerines and restrain the bud of potato and yam.
