Special Issue Information

Dear Colleagues,

The various sectors of modern industry are constantly looking for ever more efficient, but also economical and sustainable materials. To meet new needs, it is necessary to think not only in terms of raw materials, compositions, and microstructures but also in terms of manufacturing processes and architectures.

Because of their great diversity of properties (mechanical, chemical, electrical, biological, etc.), silicate materials, including ceramics, glasses, glass ceramics and geopolymers, constitute an important family of materials wildly used in many industrial sectors: automotive, aeronautics, aerospace, health, electronics, energy, etc.

The final characteristics of a product are the result of a set of parameters associated with each step of its production, especially the choice of the raw materials and the shaping technology. Therefore, the innovation in the manufacturing processes to achieve specific microstructures and architectures is a key axis of research to strengthen and increase the application fields of silicate materials and their presence in advanced products.

Within the scope of this Special Issue, it is our pleasure to invite you to submit original research papers, short communications, or state-of-the-art reviews related to silicate materials. The topics of interest include, but are not limited to:

  • Alternative shaping routes such as : additive manufacturing, freeze casting, etc.
  • Alternative sintering methods suche as : microwaves, cold sintering, SPS, etc.
  • Correlation processing/microstructure/properties;
  • Modeling of processes or properties;
  • Design of functional devices/prototypes (e.g., for catalysis, filtration…);
  • Innovative characterization methods such as : in situ monitoring of drying, sintering, non-destructive methods, etc.

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. Ceramics is an international peer-reviewed open access quarterly 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 1600 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.

This study examines the impact of the impregnation of fireclay-based conventional (CC) and medium-cement castables (MCCs) with liquid sodium silicate glass under vacuum conditions. The goal is to assess how this treatment affects the physical and mechanical properties and durability (alkali and thermal shock resistance) of these castables used in biomass combustion boilers, where they are exposed to temperatures up to 1100 °C. The research work employs standard test methods to evaluate the physical and mechanical properties. Additionally, advanced techniques such as scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and specific tests for alkali resistance and thermal shock resistance are used. The research findings suggest that impregnation with sodium silicate glass under vacuum significantly enhances the alkali resistance of both CC and MCCs. This improvement is primarily due to the reduction in porosity and the increase in density. SEM images reveal that the impregnated samples are coated with a glassy layer and the pores are partially filled with sodium silicate. Tests for alkali resistance demonstrate the formation of a protective glassy layer (with a thickness of 0.9–1.5 mm) on the castable surfaces, thereby reducing the further penetration of alkali into deeper layers of the samples. However, it is important to mention that the impregnated refractory castables have reduced resistance to thermal shock cycles. Full article
