Influence of sample preparation on determined nanomechanical properties of metastable calcium carbonate polymorphs

Popis výsledku v původním jazyce

Synthetically prepared metastable calcium carbonates (CaCO3) polymorphs, vaterite and aragonite, were used for nanoindentation testing. Nanomechanical measurements were done on samples embedded in epoxy resins. Hardness and reduced modulus were determined and both values were found to be higher for vaterite. Hardness was determined to be in the ranges 1.1 to 0.2 and 0.5 to 0.1 GPa for vaterite and aragonite, respectively. Reduced modulus was found to be in the ranges 32 to 5 and 18 to 4 GPa, for vaterite and aragonite, respectively. Reduced modulus of vaterite was found to be approximately three times lower in comparison with vaterite sample prepared as pressed pellets. These results may be helpful for designing new products containing CaCO3 for applications.n
