cuprous oxide

We manufwacture cuprous oxide of different grade by ourselves.Good quality,low price&good service is our life.

Cuprous OxideMolecular formula: Cu2OMolecular Weight: 143.08CAS: 1317-39-1Character: Cuprous Oxide is red powder with density 6.00, melting point 1235°C, boiling point 1800 °C, it dissolves in hydrochloric aid, ammonium chloride and ammonia water, it doesn’t dissolve in alcohol or water. It can be slowly turned into coper oxide in wet weather, and it is very steady and poison in dry weather.Usage: It’s used as antipollution paint in the bottom of ship to kill lows froms of marine animal lives; it can be also used as germicide, colorant in ceramics and enamel, coloring kinds of nantokites, analytical reagent and rectifiter electroplate of electric appliances industry. Specification:

Package: Well packed by three layers of kraft paper and one layer of aluminum foil paper, with the net wight 25kgs.Storage & Transportation:It should be stored in dry storehouse with well vent. Do not mix with oxidant. The container must be sealed up to prevent cuprous oxide metting with air to turn intostrong acid. Do not transport together with strond acid, alkali and foodstuff. When in fire, it can be rescued by water.
