Features of metal gold powder products:
Gold is a transition metal that can form trivalent and monovalent positive ions after being dissolved. Gold does not react chemically with most substances, but can be corroded by chlorine, fluorine, aqua regia and oxides. Gold can be dissolved by mercury to form gold amalgam (this is not a chemical reaction): nitric acid that can dissolve silver cannot dissolve all

Gold is the most malleable metal. One gram of gold can be beaten into a square meter of sheet, or one ounce of gold can be beaten into 300 square feet. Gold leaf can even be beaten to be translucent, and light shining through it will appear greenish-blue because gold reflects yellow and red light very well. Nano-scale gold material has a significantly different malleability and is extremely brittle and easily broken. Gold foil 300 atoms thick must be lifted up by static electricity using red squirrel hair, otherwise it will be easily damaged.
