Melting point 1235 ° C Relative density 6.0 Solubility Insoluble in water and alcohol, soluble in hydrochloric acid, ammonium chloride, ammonia, slightly soluble in nitric acid. Dissolved in hydrochloric acid to form white cuprous chloride crystal powder. It can be dissolved in a solution such

Formaldehyde method The copper sulfate is directly reduced by formaldehyde, and the obtained copper powder particles are coarse and have poor uniformity. Pre-reduction of copper sulfate with glucose, under alkaline conditions, reduction with formaldehyde to obtain a purple-red ultrafine copper powder with a particle size of 20 to 400 nm. Using sodium as a reducing agent, copper
