PHYSICAL AND CHEMICAL PROPERTIES
Grey powder. The average particle size is approx. 100 nm. Single particles have the average size of 70-150 nanometers and form microagglomerates. Bulk density is approx. 5.8 g/cm³. Under mechanical impact (vibration, etc.), bulk density can increase. Specific surface measured by the BET method is 6.5 m2/g. The powder is a fully crystalline silver. When heated in inert atmosphere, silver powder releases excess energy the origin of which is still unknown. The melting point is 960 °С.
Silver powder is an odious dust. Produces a harmful effect when in the human body. Neutral to environment, does not require any special precautions.
Characterized by low toxicity. Toxic dose is 60 mg. Fatal dose is 1.3-6.2 g.
Use respirators when handling the powder. Sanitary and hygienic regulations must be observed. In case of skin contamination, wash the skin with soap.
