General description
Calcium oxide (CaO), also known asquicklime, is an ionic compound widely recognized for its high reactivity andversatility. This product features a particle size of <160 nm, a density of3.3 g/mL at 25 °C, and an assay of 98% trace metals basis. Calcium oxideappears as a white solid and is highly hygroscopic, readily reacting withmoisture in the air. Calcium oxide is extensively utilized in variousindustrial applications, including the production of cement and glass, where itacts as a flux. It is also employed in the steel industry as a slag conditionerand in the manufacturing of calcium hydroxide through hydration. Additionally,CaO is used in water treatment processes to adjust pH levels and in theproduction of calcium-based chemicals. CaO is also used in:Synthesis of Nanoparticles:Calcium oxide serves as a precursor in the synthesis of calcium-basednanomaterials, which have applications in catalysis and drug delivery. Glass Manufacturing: Fluxing Agent: CaO is used as a flux inglassmaking to lower the melting point of silica, improving the melting processand enhancing the properties of the glass.
Application
- Use of Calcium Oxide in Sustainable Concrete Production: Investigates the role of calcium oxide in enhancing the anti-carbonation properties of alkali-activated slag concrete, suggesting its utility in sustainable building practices (P Shi et al., 2024).
- Calcium Oxide from Agroindustry Waste for Dental Applications: Evaluates the synthesis of calcium oxide nanoparticles from eggshell waste, focusing on their potential in promoting dental tissue regeneration (J do Amparo Madureira et al., 2024).
- Calcium Oxide in High-Ash Coal Slime Remediation: Discusses the use of calcium oxide in soil amendments derived from high-ash coal slime, enhancing adsorption performance for environmental cleanup (Y Tian et al., 2024).
- Development of Calcium Oxide-Based Activators: Details the use of waste calcium oxide fly ash as an activator in the vulcanization of natural rubber, reducing the need for zinc oxide and enhancing environmental sustainability (W Naebpetch et al., 2024).
