Nanopowder Compounds

Calcium carbonate (CaCO3) is a very abundant mineral in nature. Calcium carbonate-based nanomaterials are widely used in the food and pharmaceutical industries.

Calcium carbonate nanoparticles (CaCO3) is the most widely used filler or extender material in paper, paint, plastic, sealant, adhesive, food, ceramic, textile, cosmetics, medicine, and several other industries. Calcium carbonate nanoparticles were also found superior to other pigments in light-induced aging experiments.

Calcium carbonate nanoparticles present in three common polymorphs such as calcite, vaterite, and aragonite. Calcite has a high stability index and being studied in various sizes, shapes, and structures and naturally found in trigonal crystalline form. The other two polymorphs that exist in metastable forms are vaterite usually colorless with hexagonal crystal system and aragonite is also naturally occurring carbonate minerals.

Calcium carbonate-based material present the biodegradability and biocompatibility properties which is ideal as a smart carrier to deliver genes, enzymes, and drugs. Calcium carbonate nanoparticles are also available in passivated, ultrahigh purity, high purity and coated and dispersed forms with dimensions ranging from 5–350 nm in diameter. Modification of calcium carbonate nanoparticles with polymeric micelles has been investigated for thermodynamic and mechanical stability properties.
