FIELD: physics.
SUBSTANCE: invention relates to the manufacturing of bulk microwave energy absorbers from high-temperature absorbent material, used in high-frequency channels of electronic equipment. The method of making bulk microwave energy absorbers involves making absorbers of the required configuration from ceramic workpieces by mechanical processing. To increase heat-conductivity of the absorbers and ensure stability of their radio characteristics, the obtained absorbers are saturated with a composition containing Elasil sealant 137-182, diluted with nefras in ratio of 1:1, at temperature of 25±10°C and pressure of 1.3-2.6 kPa for 30 minutes, and then at pressure of 300-400 kPa for 5-10 minutes, followed by drying at temperature of 25±10°C for 24 hours.
EFFECT: high heat-conductivity of the absorbers and ensuring stability of radio characteristics thereof.
