Graphite


There is an inconspicuous material that plays a crucial role in various high-tech products, including but not limited to semiconductors, photovoltaics, new energy, optical fiber communication, aerospace, and nuclear energy. This material is graphite.


By paying a little attention to financial news, one can find a continuous stream of reports on the increase in graphite production capacity.

Among its various applications, graphite is particularly relevant to the photovoltaic and lithium battery industries, where graphite products are extensively consumed in the production of lithium battery anode materials and graphite crucibles.

Isostatic graphite products have high requirements for the raw materials used in compression. Firstly, the purity of the raw materials must be exceptionally high, and secondly, the particle size must be fine and evenly distributed. This involves the processes of crushing and particle size detection in the production procedure.

The production of isostatic graphite products demands high requirements for the raw materials used in compression. Firstly, the purity of the raw materials must be exceptionally high, and secondly, the particle size must be fine and evenly distributed. This involves processes such as crushing and particle size detection in the production process.

For grinding below 20um, airflow mills and Raymond mills are good options.

As for particle size detection, air jet sieves are widely used equipment in the industry.

Once the quality of the raw materials is guaranteed, the production process includes pre-pressing, pressing, carbonization, impregnation, and graphitization, leading to the final product.

China is a net importer of isostatic graphite, and as the size requirements for isostatic graphite increase with the size of silicon wafers, the domestic production capacity of high-end isostatic graphite products is insufficient. Therefore, the demand for imports remains high, resulting in a high dependence on imports.
