Ceramic samples based on the microcrystalline powders (Cu₁₋ₓAgₓ)₇GeSe₅I (x = 0, 0.25, 0.5, 0.75, 1) were prepared by pressing them at a pressure close to 400 MPa and subsequent annealing at 873 K for 36 hours. Using the microstructural analysis, the average size of microcrystallites of these samples...
