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.
