We report the integration of an unconventional filler ferrosilicon nitride (FSN), within two elastomers, to develop composites having concurrent magnetic field‐tunable viscosity and electromagnetic radiation shielding capabilities. FSN is a refractory ceramic which possesses soft ferromagnetic nature low electrical conductivity at room temperature. Moreover, porous microstructure light weight enables disperse uniformly making it attractive magnetically active filler, domain that remains unexplored. Recycled FSN, possessing irregular morphology was integrated varying parts per hundred rubber hydrogenated nitrile butadiene (HNBR), liquid silicone (SR), different values stiffness. displays good dispersion HNBR matrix leading improved mechanical properties; however, minor agglomeration occurs softer SR. The fillers align well with external field sweep 0 ↔ 1 T, effectively altering by 42% in 59.3% Furthermore, demonstrate excellent across X Ku bands. primary mode absorption through resonance particles, subdued reflection component. Thus, recycled can be capitalized where functionality should complement sustainability 3R targets.
