Nickel-coated graphite powder is a new type of electromagnetic shielding material. my country’s production capacity is constantly improving

Nickel-coated graphite powder refers to a composite powder with graphite particles as the core and metal nickel as the outer layer. Compared with pure graphite powder, nickel-coated graphite powder has higher hardness, strength, better lubricity, electrical conductivity, corrosion resistance, thermal stability, and electromagnetic shielding properties. It is used in electronics, chemical industry, metallurgy and other fields. widely. According to different uses, nickel-coated graphite powder can be divided into two categories: thermal spraying and additive nickel-coated graphite powder.

The main production methods of nickel-coated graphite powder include wet hydrogen reduction method, which refers to the method of uniformly depositing nickel on the surface of graphite particles from the nickel sulfate ammonia complex solution to generate nickel-coated graphite powder; mechanical synthesis method, which refers to the method of producing nickel-coated graphite powder. Graphite powder and nickel powder are used as raw materials, and nickel-coated graphite powder is generated through mixing, ball milling, screening, drying and other processes.

Nickel-coated graphite powder is an important type of electromagnetic shielding powder material. It can achieve a wide range of high-frequency and low-frequency shielding effects and is widely used in communications, electronics, medical and other fields. Nickel-coated graphite powder can also rely on good conductivity It can be used in the production scenarios of conductive adhesives, conductive inks, conductive coatings and other products to improve the conductivity and stability of products. It can also be used in the production scenarios of acid and alkali resistant pipelines and corrosion-resistant pumps due to its excellent corrosion resistance. In addition, In addition, nickel-coated graphite powder can also be used as a thermal spray material for grindable sealing coating manufacturing scenarios.

According to the“2023-2028 Nickel-clad Graphite Powder Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center It shows that nickel-coated graphite powder has a wide range of uses, and its application areas cover high-tech fields such as electronics, medical care, and communications. Under the current background of rapid development in downstream application fields, domestic demand for nickel-clad graphite powder is increasing, and the industry has broad prospects for development.

However, due to technical limitations, the number of domestic enterprises with the production capacity of nickel-coated graphite powder is still relatively small. There are only a few such as Ya’an Baitu High-tech Materials Co., Ltd., Chongqing Xinfubai Technology Co., Ltd., and Jinchuan Group Co., Ltd. The output is still relatively low. In the future, under the background of continuous improvement of local enterprises’ technology and strengthening of R&D strength, my country’s nickel-clad graphite powder production will continue to increase, and the industry development trend will be positive. For example, the Ya’an Baitu High-tech Materials project with an annual output of 50 tons of nickel-clad graphite is currently under construction.

Industry analysts said that nickel-coated graphite powder is a new type of electromagnetic shielding material that has the properties of metal. The electrical conductivity, lubrication performance and magnetic shielding performance of stone grinding are better than pure graphite powder. It can be widely used in electronics, communications, metallurgy and other fields, and the market development space is broad. The production of nickel-coated graphite powder is technically difficult. Currently, there are only a few companies with production capacity in my country, and the production capacity is still relatively low. In the future, local companies will need to continue to improve their technology and increase product research and development efforts.
