This article discusses the properties and applications of calcium oxide nanoparticles. Calcium is a Block S, Group 2, Period 4 element, while oxygen is a Block P, Period 2 element.
Nanoparticles that occur naturally such as volcanic ash, soot from forest fires or the incidental byproducts of combustion processes are physically and chemically heterogeneous and often termed as ultrafine particles.
Calcium oxide nanoparticles are spherical or faceted high surface area oxide magnetic nanostructure particles that serve as adsorbent for decolorizing various dye solutions. Their size can be determined using powder x-ray diffraction studies.
The chemical properties of calcium oxide nanoparticles are outlined in the following table.
||Calcium – 2
Oxygen - 16
||Calcium – [Ar] 4s2
Oxygen - [He] 2s2 2p4
The physical properties of calcium oxide nanoparticles are given in the following table.
The thermal properties of calcium oxide nanoparticles are provided in the table below.
Calcium oxide nanoparticles can be synthesized by using solution combustion method.
The key applications of calcium oxide nanoparticles are listed below:
- Biofuel applications
- Flame retardants
- It is also used in the clean up of toxic contamination from chemical warfare.
