Special Issue Information
Dear Colleagues,
Materials based on zirconium dioxide are among the most widely used materials in modern technology. This is due to a unique combination of electrical, chemical, optical, and mechanical properties, such as high hardness, strength, fracture toughness, oxygen ion conductivity at elevated temperatures, insulating properties at room temperatures, wide spectral transmission range, high refractive indices, chemical inertness and biocompatibility, low thermal conductivity, and catalytic activity. Currently, these materials are used for the manufacture of tools for processing materials by cutting and pressure, solid electrolytes in electrochemical devices, medical implants, thermal barrier and protective coatings, as well as passive and active optical elements in photonics.
The growth of single crystals based on zirconium dioxide is associated with a number of difficulties caused by high melting temperatures, as well as the presence of several polymorphic modifications of zirconium dioxide that are stable in certain temperature ranges. This imposes the need to choose appropriate methods of crystal growth. The synthesis of low-temperature monoclinic modification single crystals is possible by vapor-phase deposition, from a flux hydrothermal method. The growth of high-temperature tetragonal and cubic modifications of single crystals is carried out by optical zone melting and by a skull melting technique.
Studies of the structure and properties of single crystals contribute to a deep understanding of the fundamental properties of materials; this allows us to establish crystal chemical regularities of structure formation, the formation and interaction of structural defects, and their effect on the functional characteristics of the material. For a number of applications, such as photonics, optics, and electronics, the synthesis of high-quality single crystals is crucial.
We kindly invite researchers to contribute to this Special Issue, which is intended to provide new ideas and achievements in synthesis, the study of crystal structure, physical and chemical properties, as well as the use of single crystals based on zirconium dioxide.

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. Crystals 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 2100 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.
