High Purity 99% Copper Oxide Powder

                                                                             High purity 99% copper oxide powder
Character:
Cupric Oxide is the black non-finalize design powder or crystallize, pellet (monoclinic crystal) with density 6.313, melting rate 11.80KJ/mol, hardness 3.4, dielectric constant 18.10.
It doesn't dissolve in water, but dissolves is in acid, ammonia 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.
