Special Issue Information

Dear Colleagues,

Mullite (3Al2O3·2SiO2) is an aluminosilicate characterized by excellent physical properties, such as good resistance to thermal shock, low thermal conductivity, good resistance to wear and deformation, working temperature over 1200 °C, etc., which make it an important ceramic material. In this way, ceramic materials based on mullite find application in different technological fields as refractory material (metallurgy, glass, ceramics, etc.), matrix in composite materials for high temperature applications, substrate in multilayer packaging, protective coatings, components of turbine engines, windows transparent to infrared radiation, etc.

However, mullite is scarce in nature so it has to be manufactured through different synthesis methods, such as sintering, melting + crystallization or through a sol-gel route. Commonly, mullite is fabricated from pure technical grade raw materials, making the manufacturing process expensive. An alternative to lowering the cost is the use of mining waste as silica and alumina feedstock, which are the necessary chemical compounds required to manufacture mullite ceramics. In addition to the economic benefits, the use of mining waste brings environmental benefits as it prevents the over-exploitation of natural resources and reduces the volume of mining waste that needs to be managed.

For this Special Issue on “Mining Waste as Raw Materials for Mullite-Based Ceramics”, researchers can report findings on the use of sterile materials generated in mining activities (rubble, sludge, etc.) for the manufacture of ceramic materials containing mullite as a main crystalline phase (refractories, porcelain, porcelain stoneware, substrates, filters, coatings, membranes, composites, etc.). Given your reputed experience in this field and the outstanding impact of your previous publications, we would very much appreciate your contribution in this Special Issue of Minerals.

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 papers will be 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 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.
