          Characteristics  

          Small blue and clean crystal, odorless, density:2.284g/cm3, soluble in water and diluted the solution  appear weak acidity. It will be efflorescence slowly in dry air, and its surface wil become thite powder substance. It will lose four crystal water when heated to 110°C, and will be changed into white anhydrous copper sulfate which is easy to absorb water when the temperature is higher than 150°C.

          Uses 

          It is for the ion additive of sulfate salt plating copper and wide temperature,high bright acidity plating copper.  It is mainly used to high grade plating fields f science research, IT industry and chemical agent because the impurity contents of Fe, Ca,Pb,As,Co,Ni are lower than the copper sulfate specification of chemical agent in GB665-88 standard.
