cupric oxide

Character  Cupric Oxide is the black non-finalize design powder or crystallize, pellet (monophase powder) with density 6.313, melting point 1446°C, melting rate 11.80KJ/mol, hardness 3.4, dielectric constant 18.10. It doesn’t dissolve in water, but dissolves is in acid, ammononia water, ammonium chloride, then turns into blue solution. It can be also turned back to copper powder with hydrogen or carbon monoxide in high temperature.
