Cuprous Oxide

Product Category: Electronic Chemicals

CAS No.: 1317-39-1
Formula: Cu₂O
Molecular Weight: 143.09
Characters: Red powder. Specific wt.: 6.00,m.p.: 12350C,b.p.: 18000C. Can be easily oxidized in humid air, soluble in acids and 浓ammonia water, ammonium chloride, insoluble in water and alcohols. Will be slowly oxidized into cupric oxide in humid air; stable in dry air; toxic.
Product Usage: It is used for ship bottom anti-fouling paint, bactericides, ceramic colorant, glass staining agent, and analytical reagent etc.
Packaging: In 25Kg composite paper bag lined with plastic bag, closed tightly.
Storage Precautions: Stored in dry and draughty warehouse; no mixing with oxidants; containers should be sealed tightly to prevent air; kept away from strong acids, alkali and food; fight fire with water.
