Application fields of isostatic graphite block

Isostatic graphite blocks are an important graphite material. Due to their excellent electrical conductivity, thermal conductivity, high temperature resistance and chemical stability, they are widely used in many fields. This article will introduce the basic concepts, performance characteristics and application fields of isostatic graphite blocks in detail.

1. Basic concepts of isostatic graphite blocks

Isostatic graphite blocks are a type of graphite material made from natural graphite after high temperature and high pressure treatment. During the production process of isostatic graphite blocks, the graphite raw materials are placed in a mold and then heated under high pressure to change the graphite crystal structure and eventually form a high-density graphite block. The density of isostatic graphite blocks is relatively high, reaching 2.0-2.3g/cm3, and its internal structure is uniform and has good physical and chemical properties.

2. Performance characteristics of isostatic graphite blocks

Isostatic graphite blocks have the following performance characteristics: High conductivity: Isostatic graphite blocks have very good conductivity, and their conductivity can reach 10^5-10^7S/m, which is more than 1.5 times that of copper. High thermal conductivity: The thermal conductivity of isostatic graphite blocks is also very good, and its thermal conductivity can reach 200-400W/m·K, which is higher than the thermal conductivity of copper. High temperature resistance: Isostatic graphite blocks can work at extremely high temperatures, and their working temperature can reach above 3000℃. Chemical stability: Isostatic graphite blocks have good chemical stability and can be used in corrosive environments such as acids, alkalis, and oxidants. High mechanical strength: Isostatic graphite blocks have high mechanical strength, and their tensile strength can reach 100-200MPa.
