Production method and use of copper oxide?
Copper powder oxidation process uses copper ash and copper slag as raw materials, which are roasted and heated by gas for preliminary oxidation to remove moisture and organic impurities in raw materials. The primary oxides are naturally cooled, crushed and then re-oxidized to produce crude copper oxide. The crude copper oxide is added into the reactor pre-packed with 1:1 sulphuric acid and reacts under heating and stirring unt...

How to identify the purity and preservation of copper and gold powder?
The commonly used method for the determination of high-content copper is still the old iodometric method. The amount of potassium iodide is large, the cost is high and the time-consuming is much. The newly developed spectrophotometric method is not suitable for the determination of high-content copper because of the problem of copper developer. Therefore, it is necessary to study and develop new developer. In this paper, the a...

Detailed description of the preparation of ultra-fine copper powder?
The traditional electrolytic copper powder is generally over 10 um because of its large particle size, which is not suitable for the preparation of nano-scale ultra-fine copper powder; the atomization method is difficult to solve the problem of oxidation resistance, so it is difficult to popularize. In addition to the traditional electrolysis and atomization methods, there are many existing preparation methods, such as physica...

Copper powder production methods and status quo!
Copper powder production methods are mainly divided into: electrolysis, water atomization and redox methods. Electrolysis has a long history and mature technology. Copper powder produced has the characteristics of dendritic micro-shape, developed specific surface, high purity and good formability. However, it is produced by electrolysis. Copper powder has the disadvantage of serious environmental pollution and high energy cons...

What is the difference in physical properties between air-atomized cop...
The sphericity of atomized powder is better because the cooling rate is slower than that of water atomization, and the sphericity of broken metal droplets is better than that of water atomization for a long time. Water atomization is due to the irregular shape of the fast cooling speed and harder (similar to steel quenching). In addition, the oxygen content of air atomization is slightly lower than that of water atomization...

What is copper and gold powder? What kinds of classification are there...
Copper-gold powder (also known as gold powder) is a kind of metal pigments with scaly structure, floating in binder, golden luster and pigmentary properties, which is made from copper-zinc alloy by special mechanical processing and surface chemical treatment. Gravure printing has been widely used in plastic, high-grade pictorial, high-grade packaging, cigarette shell, securities printing, etc. because of its brilliant metal...
