Special Issue Information

Dear Colleagues,

Materials is a peer-reviewed, open access journal that publishes research spanning various aspects of the physicochemical and optical properties of special materials. It actively supports innovative investigation in the preparation, properties, and manufacturing of ceramics. This Special Issue focuses on the physico-chemical properties, process of preparation, sintering or melting of advanced ceramics. The emphasis of the collection is on pioneering scientific studies that explore the relationships between processing wet chemistry methods, phase composition, microstructure, and the physico-chemical properties of advanced ceramics, especially those obtained after arc plasma melting processes.

Manuscripts submitted to this Special Issue must provide a comprehensive description of the experimental setup, along with a critical review of the current state of knowledge regarding measurement techniques, as well as the sensitivity and accuracy of the equipment used. This Special Issue includes standard sections, such as research papers, review articles, and perspectives, welcoming both experimental and theoretical contributions. Additionally, it features news, viewpoints, and research highlights that showcase the latest scientific advancements in crystal research. With a commitment to quality, this Special Issue aims to offer strong support for authors, readers, and reviewers.

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. Materials is an international peer-reviewed open access semimonthly 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 2600 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, various raw materials, including silica sand, silica fume, calcium hydroxide, α-alumina, and nano-activated alumina, were used to produce hydroceramic systems with varying Ca/Si/Al ratios to optimize their high-temperature resistance. The hydroceramic slurries, with a constant density of 1.65 g/cm3, were all designed to have a setting time of more than 4 h at the condition of 240 °C and 50 MPa and then cured at the same condition for 2, 30, and 90 days to evaluate their long-term performances. Subsequently, compressive strength, water permeability, mercury intrusion porosimetry, thermogravimetry, and X-ray diffraction tests were conducted on set samples at various curing times to analyze the hydroceramic systems’ long-term stability and the underlying mechanism. The results indicated that the hydration reaction of α-Al2O3 was minimal, and its inclusion reduced the incorporation of silica sand in the hydration process. Nano-activated alumina improved the macroscopic properties of the hydroceramic systems and promoted the formation of a significant amount of tobermorite 11 Å. The addition of silica fume can enhance the system’s macroscopic properties and the long-term stability, promoting the reaction of silica sand. The long-term stability of slurries with a Ca/Si ratio of 1 was significantly better than that of slurries with a Ca/Si ratio of 0.5. The best-performing slurry can maintain a compressive strength of more than 19 MPa after being cured at 240 °C for 90 days. Full article
