Descrizione generale
Barium carbonate (BaCO3) is an important alkaline-earth metal material in the production of barium salts, barium ferrite, pigments, ceramics, optical glass, and electric condensers. Additionally, it serves as a precursor to produce superconductors and ceramic materials.
Applicazioni
Barium carbonate is used:
- In the preparation of barium titanate using a mixture of BaCO3 and titania (TiO2) by solid-state reaction.
- As an additive in the preparation of NBC (neodymium – barium –copper) ceramics.

Pure zinc oxide and zinc oxide/barium carbonate nanoparticles (ZnO-NPs and ZB-NPs) were synthesized by the sol-gel method. The prepared powders were characterized by X-ray diffraction (XRD), ultraviolet-visible (UV-Vis), Auger spectroscopy, and transmission electron microscopy (TEM). The XRD result showed that
