Preparation and Characterization of CaCO3 Nanowires

Abstract

Abstract: CaCO3 nanowires were synthesized from CaCO3 reagent by sol-gel process and thermal decomposition. The preparation of CaCO3 included two steps: In the first step, the wirelike intermediates containing Ca were synthesized by sol-gel process, which are with one dimension wire-like nanostructures; in the second step, the resulting samples were converted into CaCO3 nanowires by thermal decomposition. The diameter and length of the obtained nanowires are 50-80nm and up to 5μm separately. The nanowires are constited of self-assembled nanoparticles and they belong to the trigonal system.

Key words: CaCO₃, nanowire, sol-gel process, thermal decomposition
