With the rapid development of modern industry, thermal management has become a key factor affecting product performance and reliability. From high-performance computing devices to aerospace components, the selection of efficient thermal conductivity materials has become a necessary consideration for these high-end applications.
Ceramic materials have outstanding performance in the field of thermal conductivity due to their unique combination of properties. Their thermal conductivity is better than that of traditional plastic materials, and they can also provide excellent electrical insulation performance, which is very suitable for the electronics field. For example, the thermal conductivity of common aluminum nitride (AlN) ceramic materials is as high as 180 W/mK, far exceeding ordinary engineering plastics (0.2-0.4 W/mK). This superior combination of thermal conductivity and electrical insulation performance makes ceramic materials have an irreplaceable and important position in applications such as electronic packaging and heat dissipation substrates.

What is Thermal Conductivity?
Thermal conductivity is an important indicator to measure the thermal conductivity of materials. Its unit is Watt per meter Kelvin (W/mK). This performance indicator reflects the strength of the material’s thermal conductivity. You need to note that the thermal conductivity of ceramic materials is not constant. It is affected by various factors, whether it is the manufacturing process, material purity, grain size and operating temperature, which will affect the final thermal conductivity of ceramic materials.
