The manufacturing method
of copper oxide
1. Introduction

Copper oxide is an important inorganic compound, widely used in chemical industry, metallurgy, ceramics, medicine, pigments and other fields. As a raw material for the production of chemical products, the production method of copper oxide has attracted much attention. This article will introduce the manufacturing methods of copper oxide, including dry, wet and electrolytic methods.

2. dry method to manufacture copper oxide

dry method to manufacture copper oxide mainly uses copper powder and oxygen to react at high temperature to generate copper oxide. The specific steps are as follows:

1. mix copper powder with a small amount of additives and put them into a reaction kettle.
2. Oxygen is introduced to control the reaction temperature within an appropriate range to initiate the reaction of copper powder with oxygen.
3. After the reaction, the product is cooled, crushed and sieved to obtain a copper oxide product with a desired particle size.

dry method for manufacturing copper oxide has the advantages of simple process, convenient operation and high product purity, but the energy consumption is large and the production efficiency is low.

3. wet manufacturing copper oxide

wet manufacturing copper oxide mainly uses copper salt solution and alkali solution reaction, the formation of copper hydroxide precipitation, and then by drying, roasting and other processes to produce copper oxide. The specific steps are as follows:

1. the copper salt solution is mixed with the alkali solution, and the pH value is controlled to generate copper hydroxide precipitate.
2. The copper hydroxide precipitate is filtered, washed, and dried to obtain a precursor.
3. The precursor is calcined at high temperature to decompose into copper oxide.

wet process manufacturing copper oxide has the advantages of high product purity, uniform particle size distribution and low production cost, but the process is more complex and requires strict control of operating conditions.

4. electrolysis method to manufacture copper oxide

electrolysis method to manufacture copper oxide mainly adopts the method of electrolytic copper salt solution, copper is precipitated on the cathode, and copper oxide is generated on the anode. The specific steps are as follows:

1. The copper salt solution is used as an electrolyte, and direct current is passed for electrolysis.
2. Copper is precipitated on the cathode while copper oxide is formed on the anode.
3. The copper oxide on the anode is filtered, washed, and dried to obtain a product.
The production of copper oxide by
electrolysis has the advantages of high product purity, low energy consumption and high production efficiency, but it requires a large amount of electrolyte and power supply, and the equipment investment is large.

5. Conclusion There are many manufacturing methods for

copper oxide, including dry, wet and electrolytic methods. Different methods have different advantages and disadvantages and scope of application, and suitable manufacturing methods should be selected according to specific needs and conditions. At the same time, it is necessary to strictly control operating conditions during the manufacturing process to ensure product quality and production safety.
