colorless transparent block crystal or white crystal. The relative density is 4. 352 (19 °c); Melting point 212 °c. Toxic and corrosive. Soluble in water, ethanol, ammonia, ether-soluble, glycerol. Stable in pure dry air, when heated to 450 °c, it decomposes into silver, nitrogen dioxide and oxygen. Neutral reaction with water or ethanol solution. Photosensitive. Inorganic oxidants. When combustible materials are on fire, they can contribute to the fire.
industrial production of silver nitrate is generally prepared by the reaction of silver and concentrated nitric acid.
used in photographic emulsion, silver plating, mirror making, printing, medicine, hair dyeing, electronics industry, etc. It is used in the manufacture of X-ray film, film film and photographic film in the photographic industry. In the electronics industry, it is used to prepare various new gas purification agents, conductive adhesives, AgX molecular sieves, etc., and also used to produce silver-zinc batteries, electronic components and crafts, silver plating, corrosion agents, fungicides, it is also used as a starting material for analytical reagents and other silver salts.
mouse oral LDso:50mg/kg. Accidental administration of silver nitrate can cause severe Abdominal Pain, Vomit, blood in the stool, and even gastrointestinal perforation. It is corrosive and can cause skin and eye burns. Workers with long-term exposure to this product will develop generalized psoriasis. Store in a cool, ventilated warehouse. Keep away from fire and heat source. Avoid light. It shall not be mixed with acids, flammable materials, organic materials, reducing agents, spontaneous combustion materials, wet flammable materials and so on.
