Abstract

Сomposites of the AlN–Mo system with different molybdenum particle sizes and dielectric properties: dielectric permittivity ε in the range 22–34 and the tangent of the dielectric loss tgδ = 0.008–0.016 at the frequency f = 2.9–3.1 GHz were obtained by pressureless sintering, suitable for volume absorbers of the microwave range in delay system a powerful pulse lamp running wave.
