Web29 de jun. de 2015 · $\begingroup$ But emissivity is not the same as thermal conductivity, which is a bulk property of a material. As pointed out, shiny aluminum or steel has low emissivity/absorptivity, so radiation losses are small. However, as you can easily test by putting your hand on a hot plate, the thermal conductivity is quite high. $\endgroup$ – WebThe discussion of the breakthrough technologies needed for AlN applications focuses on four problem areas: the realization of the highest thermal conductivity by sintering, pin/lead brazing, the metallization problem for the cofired case and the postfired case, and polishing for a thin-film circuit.
