Red powder; specific gravity: 6.00; melting point: 1235°C; boiling point: 1800°C; soluble in hydrochloric acid, ammonium chloride, ammonium hydroxide; insoluble in alcohol, water, slowly oxidized to copper oxide in humid air, relatively stable and toxic in dry air.
Light cuprous oxide is mainly used in the manufacture of ship bottom anti-fouling paint (to kill low-level marine animals), pesticide bactericides.
Packaging:20KG/Compound paper bag by three layer kraft paper lined with one layer of aluminized paper.
It should be stored in dry, ventilated warehouse; please separate with oxidizing agent; keep away from strong acid, strong base and food.
