Alumina ceramics have good conductivity, mechanical strength, and high temperature resistance. Its thermal conductivity varies greatly with temperature. We need to use laser flash method to test thermal conductivity. Next, we will talk about alumina ceramics themselves. In fact, this material is not entirely made of alumina, but rather contains alumina components added during the construction process. The addition of alumina greatly increases its thermal conductivity, which is a creative attempt and greatly increases the possibility of ceramic materials. Another point is that other substances, such as copper, are actually added to the conduit, which also increases the possibility of ceramics. Perhaps you don't have a specific understanding of the thermal conductivity of this material here, but don't worry, we can use the same comparative approach to look at this issue. In fact, the thermal conductivity of alumina ceramics can reach 29.3 orders of magnitude. If we still can't understand, we can refer to some relevant parameters of plastic. The thermal conductivity of general plastics is only a few orders of magnitude, while the thermal conductivity of ceramic materials is several hundred times higher. This shows the thermal conductivity of our new ceramic material.
