Physical and Chemical Properties | White luster metal (face-centered cubic crystal), ductility is second only to gold. Melting point 961.93 °c. Boiling point 2212 °c. Relative density d2010.5. Soluble in nitric acid, hot sulfuric acid, soluble in molten alkali metal hydroxide, alkali metal peroxide, alkali metal cyanide. Hydrochloric acid can corrode the surface, most of the acid is not active, do not dissolve in cold water and hot water. Silver is a good conductor of heat and electricity and is not eroded by water and atmospheric oxygen. It turns black when exposed to ozone, hydrogen sulfide and sulfur. Most silver salts are sensitive to light. |
Use | Used as electroplating and production of precision alloy, solder and other raw materials |

white metal powder. Melting Point: 960.5 °c; Boiling Point: About 2000 °c; dls 10. 49.
metal silver was used as a raw material and dissolved in nitric acid, and then added to an electrolytic cell for electrolysis. High purity silver powder was obtained after electrolytic refining.
used in the electronics industry, can be used to prepare the high temperature sintering conductive paste, conductive coatings and so on.
should be stored in a cool, dry, ventilated, light-protected warehouse, not with strong acid, flammable materials storage and mixed transport. In the process of transport to prevent rain, sun exposure.
