Special Issue Information

Dear Colleagues,

Nanoclay technology is an emerging field of applied sciences that encompasses the design, synthesis, and characterization of nanoscale clay-based composites and their applications.

In recent years, with the advancements in characterization techniques such as X-ray diffraction, electron microscopy, spectroscopy, and other related instrumental analytic procedures, the field has witnessed significant improvements toward understanding the structure and chemistry of such nanomaterials.

In the light of these considerations, I would like to invite authors to contribute original research articles, as well as review articles, focused on the preparation and characterization of clays, clay minerals, and related materials and their application in different fields ranging from environmental to biomedical, pharmaceutical, conservation of cultural heritage, catalysis, etc. Papers dealing with future innovative perspectives are strongly supported.

Aspects covered include adsorption and interfacial processes, colloid stability, surface chemistry, reactivity, synthesis protocols, characterization of the nanocomposites, mechanical, thermal, electrical properties, micro and nanophase materials, etc.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In this study, we developed formulations of a ceramic coating from clay, kaolin, quartz, talc and feldspar as a standard formulation with the addition of eggshell residue to improve the mechanical characteristics of the product. The addition of eggshell residue is justified as it will contribute to filling the formulation’s interstices. It would also help decrease the sintering temperature due to the high presence of calcium oxide in its composition. Samples with the ceramic coating (45% by weight of feldspar; 30% by weight of clay; 15% by weight of kaolin; 7% by weight of quartz; 3% by weight of talc; and additions of 5%, 10% and 20% by weight of eggshell residue) were pressed uniaxially at 70 MPa for 30 s; dried at 110 °C for 24 h; and sintered at 1000 °C, 1100 °C and 1200 °C. The main mineralogical phases (microcline, mullite, quartz and anorthite) of the sintered samples were identified by X-ray diffraction (XRD). After evaluating the physical-mechanical properties (water absorption, linear shrinkage, apparent porosity and resistance to flexion), it was observed that the incorporation of eggshell residue (5%, 10% and 20%) resulted in a significant loss of the desired physical and mechanical properties. A loss of over 50% of mechanical strength was obtained. Full article
