The Thermal Conductivity Of Aluminum Oxide Electronics

relatively low cost is combined with a relatively high thermal conductivity, especially when compared to FR4 board material. Other ceramics such as Beryllium Oxide and Aluminum Nitride feature a much higher conductivity, but at a much higher price. Hence, the thermal conductivity of Al 2 O 3 is of much interest to a designer. However, a word
