Descriptions | Chinese name: Copper(I) phosphide English name: COPPER PHOSPHIDE IUPAC name copier (I) photosphide CAS number: 12019-57-7 Molecular formula: Cu3P Molecular weight: 221.61 EINECS number: 234-647-7 Molar mass: 221.6g/mol Properties of Copper(I) phosphide Appearance: yellow gray Hexagonal crystal family crystal Color: yellow gray Melting point: 900 ℃ Crystal system: Hexagonal crystal family Relative density: 7.15 Density: 6.600 Copper price:+1 Phosphating valence: -3 Solubility: insoluble in water, insoluble in dilute Mineral acid, soluble in strong oxidizing acid (Redox occurs), Copper(I) phosphide, chemical formula is Cu3P. It is produced by Combination reaction of copper and phosphorus. It is grayish yellow, Hexagonal crystal family, brittle and does not react with water. Application: Mainly used as copper Oxygen scavenger. Copper(I) phosphide plays a role in copper alloys, that is, in Phosphor bronze, which is a good copper Oxygen scavenger. It can also be used as a synthetic material in the photochemical production of room temperature superconducting materials. Copper(I) phosphide can also be used for photochemical production by ultraviolet irradiation of sodium copper phosphate. When Copper(I) phosphide is exposed to ultraviolet light, Copper(I) phosphide will emit fluorescence. Synthesis method: Weigh copper and red phosphorus according to chemical calculations and seal them in a quartz tube. Maintain at 640 ℃ for 20 hours. However, due to the non-uniformity of the product, it is necessary to raise the temperature of the product to 1000 ℃ in a closed quartz tube and maintain it for 5 hours to fully melt the product and achieve uniformity. Copper(I) phosphide can also be produced by electrolysis from molten sodium metaphosphate containing Copper(II) oxide. |
