“…A few key areas for further exploration are summarized below: Chemistry‐based processes can be used to expand the bioactive GC composition ranges. Recently, it has been demonstrated that new gel‐derived glasses with a high ZrO 2 content can be converted to bioactive nano apatite‐zirconia GCs with improved mechanical properties Adequate matrices can be engineered for the development of hierarchical nanostructured bioactive GCs based on variations in the size, shape, distribution, and composition of nanosized crystals. Engineering of porosity is a current research field for the development of hierarchical porous bioactive GCs. New or improved crystallization processes, such as microwave heating, the biomimetic assemblage of crystals, textured crystallization, laser crystallization, and electron beam crystallization, should be developed. Coating properties should be improved.…”

The interest around bioactive glass-ceramics (GCs) has grown significantly over the last two decades due to their appropriate biochemical and mechanical properties. The intense research effort in this field has led to some new commercial products for biomedical applications. This review article begins with the basic concepts of GC processing and development via controlled heat treatments of monolithic pieces or sinter-crystallization of powdered glasses. We then go on to describe the processing, properties, and applications of some commercial bioactive GCs and discuss selected valuable reported researches on several promising types of bioactive GCs. The article finishes with a section on open relevant research directions for bioactive GC development.

High chemical stability, resistance to changes in the pH, pressure and temperature meant that zirconium oxide is widely used in many elds. It is used in water treatment and waste water treatment processes, as well as air puri cation. In this paper, selected methods of nano-zirconia synthesis in liquid phase were characterized. ese methods include, among others, the microemulsion method. Based on literature data, the advantages and di culties associated with the use of each method are presented, in order to answer the question of which method of nanometric zirconium oxide synthesis in the liquid phase is the most advantageous. e authors also pointed out some directions of development for the discussed methods, which relate to, among others, solvent change and the use of additives in the form of polymers.Keywords: nano zirconia, hydrothermal method, synthesis, microemulsion method Streszczenie Wysoka stabilność chemiczna, odporność na zmiany pH, ciśnienia i temperatury sprawiły, że tlenek cyrkonu znajduje szerokie zastosowanie w wielu dziedzinach.

Both unwanted and induced crystallization can impact bioactivity, physical and mechanical properties of bioactive glasses (BGs). Uncontrolled crystallization has negative consequences, rendering BGs unreliable. However, by manipulating the type, size, shape, and quantity of crystals in BGs, plenty of opportunities arise for controlling, for example, mechanical properties and degradability, leading to unique applications and improved performance. Understanding crystallization is a key step in developing bioactive glasses and glass‐ceramics (BGCs), and both fundamental and experimental research can aid in the design of BGCs for processing and biological function. In this perspective, we discuss the sources of crystallization and how controlled crystallization facilitates the functionalization of bioactive scaffolds, hybrids, coatings, composites, cements, and fibers.
