This research successfully analyzed silver particles synthesized via the Vertical Vapor Phase Growth (VVPG)
technique. Silver was deposited on quartz tubes and examined using scanning electron microscopy (SEM) energy-
dispersive X-ray spectroscopy (EDS) to study morphology, elemental composition, surface roughness, and Fourier
transform infrared spectroscopy (FTIR) to study functional groups in organic and inorganic materials. High-
temperature heating transformed the irregularly distributed silver particles into smooth, spherical forms
through spheroidization and Ostwald ripening. The particle sizes exhibited a range of surface textures, with
height variations up to 65.42 µm and maximum height differences (Rz values) from 2.04 µm to 9.20 µm. These
findings underscore VVPG’s capability to produce silver particles with high purity and precise surface charac
teristics, making it a valuable technique for applications requiring stable and specific surface properties. The
insights gained in this study offer potential applications in antimicrobial surfaces, medical devices, and precision
electronic components.
