Thermal conductivity of polycrystalline graphite

The so-called carbon materials such as artificial graphite molded products are polycrystalline materials with extremely complex structures, and the basic structure of graphite crystallization has strong anisotropy. Therefore, the macroscopic thermal conductivity of carbon materials, apart from relying on empirical data, is almost unpredictable. The factors that have a significant impact on thermal conductivity include:(1) The differences in the basic properties of the initial raw materials;(2) The manufacturing process - macroscopic anisotropy;(3) Heat treatment temperature - the growth degree of graphite microcrystals;(4) Apparent density, distribution of holes, etc.

Scales graphite price tends to be stable

At the beginning of the month, the price of scales in Shandong was stable as a whole. At present, the mainstream price of -195 mainstream prices are 6300-6500 yuan/ton, which is the same as last month. Entering winter, most of the scale graphite companies in the Northeast are suspended for production holidays. Although a few companies are in production, the output is reduced and the inventory reserves are not much.The scale of the scale graphite market has been poor some time ago and the demand for material resistance has declined, which led to a decline in the price of scales, and corporate quotations were chaotic. As the Spring Festival holiday approaches, due to the suspension of production in the Northeast region, graphite supply has declined, and downstream enterprises have been basically completed. The supply demand for scales graphite market is plain, and the offer is relatively stable.In 2021, the export situation of scales was relatively sluggish. According to customs statist
