Manufacturing 
   
If you add potassium hydroxide or sodium hydroxide solution to a silver nitrate solution, a brown-black silver hydroxide precipitate is formed. The product breaks down to silver (I) oxide:
   
AgNO3 + KOH AgOH + KNO3
2 AgOH Ag2O + H2O
    
  
use 
  
In the laboratory and in training, silver (I) oxide is used to demonstrate a typical thermolysis and to introduce the hydroxyl group in organic compounds. Due to its high thermal conductivity, the silver salt is contained in the thermal paste for computer processors. The paste dissipates the heat generated on the electronic component. In silver oxide batteries, the anode consists of powdered zinc and the cathode consists of silver (I) oxide. When discharging, silver is formed, the voltage is around 1.5 volts.
