“…Al incorporar residuos sólidos en las formulaciones iniciales de los productos cerámicos, debido a la heterogeneidad de los mismos, es importante adaptar los residuos a la producción de vidrios precursores de materiales vitrocerámicos mediante el control estricto de la composición química, logrando que cada residuo contribuya con una cantidad apropiada de diferentes óxidos, porque las mezclas deben contener los componentes típicos como: formadores de la red vítrea (SiO 2 , AI 2 O 3 ...), elementos modificadores (Na 2 O, K 2 O ...) y estabilizadores (CaO, MgO, ZnO, PbO...) que dan lugar a la formación de vidrios estables ; Montoya-Quesada; Villaquirán-Caicedo; Mejía de Gutiérrez, 2019). Aunque la versatilidad del proceso de producción de materiales vitrocerámicos a partir de residuos industriales ha sido reportada en diferentes investigaciones, es de destacar el uso de escorias (Ayala; Gómez; Roether; Boccaccini, 2019; Francis, 2004;Mihailova;Djambazki;Mehandjiev, 2011;Ni;Jia;Zhu;Huang, 2010;Yang et al, 2014), ceniza de carbón Leroy et al, 2001;Cheng;Ueng;Chen;Chiu, 2002;Luan;Li;Su;Cui, 2010;Hieu;Chen;Xuan;Hoang, 2012;Montoya-Quesada et al, 2019), residuos de vidrio (Kalirajan; Ranjeeth; Vinothan; Vidyavathy; Srinivasan, 2016), residuos de bagazo de caña (Teixeira et al, 2014), residuos de cobre (Yang et al, 2014) e inclusive mezclas de diferentes residuos (Barbieri et al, 1999;Barbieri et al, 2000;Francis;Boccaccin, 2004;Yoon;Yun, 2008;Cedillo, 2010;Ljati;Kamusheva;Grozdanov;…”

Glass-ceramic obtained from solid waste such as ash, slag, and glass waste: review Resumen El uso de residuos y subproductos industriales como reemplazo parcial o total de materias primas vírgenes para la producción de nuevos materiales, se ha convertido en una parte vital de la gestión de desechos, lo cual ha dado lugar a tecnologías innovadoras que permiten extender su aplicación al desarrollo de nuevos productos, contribuyendo así a la menor contaminación ambiental y a los conceptos de la economía circular. En los últimos años, la tecnología de vitrificación de residuos se ha considerado un procedimiento atractivo para el tratamiento de diferentes tipos y mezclas de residuos para la obtención de vidrios y vitrocerámicas. El presente artículo realizó una revisión de investigaciones relacionadas con la producción de vitrocerámicas densas realizadas entre 1994 y 2019, específicamente las que han utilizado cenizas, escorias y residuos de vidrio. La revisión revela que se han acumulado considerables conocimientos y experiencia en el proceso de transformación de los desechos base silicatos, en productos útiles de vidrio y vitrocerámicas con propiedades similares o incluso superiores a los obtenidos a partir de materias primas no renovables, abriendo nuevos campos de aplicación en cerámicas avanzadas.

“…Among fluorides, special attention should be paid to YF 3 and LaF 3 crystal phases characterized by wide band gap (>10 eV) and exceptionally low-phonon energies equal to~358 as well as~350 cm −1 , respectively, in which M 3+ (M = Y, La) cations from crystal lattices can be easily substituted by RE 3+ ions without any charge compensation [20][21][22][23]. Due to the above reasons, the oxyfluoride glass-ceramic materials (GCs) containing fluoride nanocrystals are considered as an interesting class of advanced optical materials, which are frequently reported in the literature [24][25][26][27][28]. Indeed, they successfully combine the advantages of the individual fluoride crystal phase with good mechanical strength and thermal durability of oxide hosts [29,30].…”

In the present work, the Tb3+/Eu3+ co-activated sol-gel glass-ceramic materials (GCs) containing MF3 (M = Y, La) nanocrystals were fabricated during controlled heat-treatment of silicate xerogels at 350 °C. The studies of Tb3+ → Eu3+ energy transfer process (ET) were performed by excitation and emission spectra along with luminescence decay analysis. The co-activated xerogels and GCs exhibit multicolor emission originated from 4fn–4fn optical transitions of Tb3+ (5D4 → 7FJ, J = 6–3) as well as Eu3+ ions (5D0 → 7FJ, J = 0–4). Based on recorded decay curves, it was found that there is a significant prolongation in luminescence lifetimes of the 5D4 (Tb3+) and the 5D0 (Eu3+) levels after the controlled heat-treatment of xerogels. Moreover, for both types of prepared GCs, an increase in ET efficiency was also observed (from ηET ≈ 16% for xerogels up to ηET = 37.3% for SiO2-YF3 GCs and ηET = 60.8% for SiO2-LaF3 GCs). The changes in photoluminescence behavior of rare-earth (RE3+) dopants clearly evidenced their partial segregation inside low-phonon energy fluoride environment. The obtained results suggest that prepared SiO2-MF3:Tb3+, Eu3+ GC materials could be considered for use as optical elements in RGB-lighting optoelectronic devices operating under near-ultraviolet (NUV) excitation.

“…The density, which increased with the sintering time and temperature from 4.059 to 4.716 g/cm 3 , portrayed rapid densification. This pattern significantly represented the actual behavior of atomic diffusion, where diffusivity was increasing proportionally to the temperature applied [41]. Higher temperatures supplied sufficient energy causing the grain boundaries diffusion to happen between the host particles.…”

In this study, the authors attempted to propose the very first study on fabrication and characterization of zinc-boro-silicate (ZBS) glass-ceramics derived from the ternary zinc-boro-silicate (ZnO)0.65(B2O3)0.15(RHA)0.2 glass system through a conventional melt-quenching method by incorporating rice husk ash (RHA) as the silica (SiO2) source, followed by a sintering process. Optimization of sintering condition has densified the sintered samples while embedded beta willemite (β-Zn2SiO4) and alpha willemite (α-Zn2SiO4) were proven in X-ray diffraction (XRD) analysis. Field emission scanning electron microscopy (FESEM) has shown the distribution of willemite crystals in rhombohedral shape crystals and successfully form closely-packed grains due to intense crystallization. The photoluminescence (PL) spectra of all sintered ZBS glasses presented various emission peaks at 425, 463, 487, 531, and 643 nm corresponded to violet, blue, green, and red emission, respectively. The correlation between the densification, phase transformation, microstructure, and photoluminescence of Zn2SiO4 glass-ceramic phosphor is discussed in detail.
