Sažetak

In this work, mechanochemical synthesis of calcium oxalate was done in a planetary ball mill, with and without addition of water as a solvent. Previous research was primarily focused on calcium oxalate synthesis in solution. Here we report a different approach which may contribute to new findings in calcium oxalate crystal synthesis caused by an influence of mechanical energy.
The aim of this study was synthesis, identification, and characterization of particular oxalate hydrate phase synthesized with calcium salts (chloride, nitrate and sulphate). The effects of grinding speed and reaction duration regarding the time of synthesis were investigated. Structural and thermal sample properties were studied by FTIR spectroscopy and thermogravimetric analysis (TGA). Morphologic characteristics of calcium oxalate and size distribution were measured by optical microscopy and dynamic light scattering (DLS).
