Growth and microhardness studies of mixed crystals of (NH₄)₂SbF₅-K₂SbF₅

260-263Mixed crystals of (NH4)2SbF5-K2SbF5 , an electro-optic material have been grown by isothermal evaporation technique. Powder X-ray diffraction method has been used for structural identification and determination of lattice parameters. Load dependent microhardness measurements on this crystal reveal the mechanical behaviour of the material. The work hardening co-efficient and the yield strength of the material were found to be 11.66 and 2.058 Mpa, respectively
