ỨNG DỤNG
Sodium
cyanide serve the same purpose, can be common. Than sodium cyanide plating more
highly conductive performance, plating meticulous and other advantages, the use
of more appropriate, but the price is more expensive. For ore flotation to
extract gold, silver. Heat treatment of the steel, manufacturing of organic
nitriles. Analysis of the chemical used as a reagent. In addition, also used
for photography, etching, lithography, etc.
