A scientometric analysis of eggshell-based composite literature with research mapping knowledge

Eggshell, a readily available natural material, possess remarkable properties that enhance the mechanical and tribological performance of composites, as evidenced by numerous studies. However, a scientometric analysis specifically examining the research landscape of eggshell-based composites has not been previously conducted. This study addresses this gap by employing a data processing, mining, analysis, presentation, and contemporary visualization approach to analyze bibliographic data on the effects of eggshell in composites. This analysis aims to inform researchers and guide future research directions in this promising field. Scopus data was utilized for the scientometric analysis, which encompassed publishing sources, leading authors, frequently used keywords, key publications, and the countries with the most significant contributions. The analysis revealed that "eggshell" is a prominent keyword within the field. Additionally, "Key Engineering Materials" emerged as a publication source with a high number of citations and articles. Notably, India was identified as the leading country in terms of research output. The graphical and quantitative representation of researchers and nations presented in this study facilitates knowledge sharing and fosters collaborative research efforts among academics. Furthermore, this study strengthens the evidence for eggshell potential to improve the mechanical and tribological properties of composites across diverse applications. However, it is crucial to acknowledge that the pre-treatment method and composite composition significantly influence the final material's strength and durability. Nature-derived materials, such as eggshell, hold immense promise for utilization as bio-ceramics in composites, paving the way for the development of environmentally friendly products.Numerous studies have explored the use of eggshell as a composite material to address environmental concerns.Eggshell exhibit unique characteristics that enable them to serve as replacements for conventional friction materials, thereby mitigating the generation of wear debris that poses detrimental environmental impacts.
