Graphite boards, commonly made from graphite, are widely used as thermal conductive materials or conductive materials in the electronic industry due to their excellent physical and chemical properties. But what is the thermal conductivity of a graphite board? Let me explain for you:

Graphite has a thermal conductivity of 151 W/(m·K).

Thermal conductivity refers to the amount of heat transferred through a material of 1m thickness under steady-state heat transfer conditions, where the temperature difference across the two surfaces is 1 degree (K, °C), within 1 second (1s), through an area of 1 square meter. The unit is watts per meter per degree (W/(m·K)).

Thermal conductivity varies among different materials, and for the same material, its thermal conductivity is related to factors such as structure, density, humidity, temperature, and pressure. Generally, the thermal conductivity is lower when the moisture content of a substance is low and the temperature is lower. Typically, the thermal conductivity of solids is greater than that of liquids, and the thermal conductivity of liquids is greater than that of gases. This difference largely stems from the varying distances between molecules in these two states.

Graphite's chemical composition is primarily carbon, with numerous natural graphite minerals found in nature. Graphite sheets are a new type of heat-conductive material that can evenly conduct heat in two directions. Although non-metallic, they possess the electrical conductivity of metallic materials and the malleability of organic plastics, along with good thermal conductivity and chemical stability at high temperatures. As a result, graphite sheets are widely used in various fields such as electronics, telecommunications, lighting, and aerospace.
