The remediation of water from organic pollutants, such as dyes and related compounds and the reuse of discarded glasses, represents fundamental challenges in highly industrialized countries. Porous glass microspheres have been proposed as efficient adsorbents in wastewater treatment, but their real application is problematic, especially from the pe...

Silicate bioceramics, including systems based on the simultaneous presence of wollastonite (CaSiO3) and diopside (CaMgSi2O6), are of great interest in bone tissue engineering applications, especially in form of variously shaped three-dimensional scaffolds, as determined by application of several additive manufacturing technologies. In this framewor...

Silicone polymers are already known as feedstock for a variety of silicate bioceramics, in the form of scaffolds with complex shapes, obtained by Vat Photopolymerization. Printing is enabled by using silicone blended with photocurable acrylates. The development of a particular silicate composition that functions as a glass or glass-ceramic precurso...

Knowledge about the lithology of rock art mediums is important to establish the consequences of weathering processes affecting the rock and its heritage. Besides, it allows us to determine the best methods for preserving rock art from natural and human impacts. The objective of this paper is to assess the degree to which degradative processes have...

Tafoni, produced by physicochemical weathering of sandstones, are abundant in the Cerro Colorado (Córdoba province, Argentina). Many of the rock shelters are decorated with rock art of high heritage significance. This art belongs to semisedentary communities from the Late Prehispanic Period (ca. 1550–350 AP). They include morphologies inherited fro...

Refractory ceramic materials were manufactured, mainly composed of magnesia grains (coarse and medium fraction) and CaZrO3/MgO as a binding phase produced from the reaction sintering between CaMg(CO3)2 (dolomite) and m-ZrO2 (monoclinic zirconia), which constituted the finer fraction. Different relationships between the proportion and the size of th...

El presente trabajo da cuenta del desarrollo y prueba de funcionamiento de un dispositivo para impresión 3D de cerámica basado en la técnica Paste Deposition Modeling (PDM) del tipo de pistón mecánico de una etapa. La PDM es un método de Manufactura Aditiva de cerámicos similar al Filament Depositiong Modeling (FDM) para polímeros, salvo que la tra...

Glasses were synthesized with different theoretical contents of leucite and Bioglass 45S5 using different raw materials for the contributions of Al2O3 and K2O in order to study crystallization and sintering, and to study raw materials and composition influence on those processes. Each proposed composition was produced by duplicate, using different...

The discarded solutions by the chemical nickel industry have high amounts of nickel, this is why they are considered hazardous wastes for the health and the environment. On the other side, Ni particles can have potential applications in the developing of magnetorheological fluids currently being used to improve the performance of mechanical devices...

A quantity of 3 mol% yttria‐partially stabilized zirconia (Y‐TZP) with 10.5 and 19.9 vol% 64S bioglass compacts was sintered at different temperatures up to 1500°C. The influence of 64S glass addition on the sintering kinetic, flexural strength, and osteoblast cell response of Y‐TZP ceramics was investigated. The addition of 64S glass increased the...

Four glass compositions were produced taking into account different theoretical Leucite (KAlSi2O6)/Bioglass 45S5 (45 % SiO2, 24.5 % Na2O, 24.5 % CaO, 6 % P2O5) ratios using analytical grade reagents only; and replacing some of the reagents by natural minerals, all that were found to be bioactive when they were transformed to glass ceramics. Glasses...

3 mol% yttria-partially stabilized zirconia (Y-TZP) powder and a sol-gel derived CaO-P2O5-SiO2 (64S) bioglass, were used to produce Y-TZP- bioglass slip cast compacts. The rheological properties of concentrated aqueous Y-TZP-64S suspensions prepared with two different glass contents: 10.5 vol% and 19.9 vol%, and ammonium polyacrylate (NH4PA) as dis...

Two glass-ceramics composition were produced from natural minerals. Quartzes and feldspars were pre-selected on the basis of their purities studied by X-ray diffraction (XRD) and chemical analysis. Prepared compositions of glasses precursors were two different theoretical leucite (KAlSi2O6)/Bioglass 45S5 (L/Bg) ratios. Transformations of raw materi...

Thermal transformations of glasses with formulations derived from Bioglass 45S5 with Al2O3 (≤2.5 wt %) and K2O additions through K-feldspar were studied. Crystallization kinetics and transformations were followed-up by X-ray diffraction and differential thermal analysis. The activation energy of crystallization of Na2CaSi2O6 was found to be lower t...

Bioceramics are widely used materials as filling bone and implants, which can be classified into three groups according to their reactivity with the body fluid and its interaction with the bone tissue: bioinert, resorbable or bioactive. Within the last class mentioned are bioactive glasses and glass-ceramics.

Bioglass 45S5 has been successfully implemented in clinical applications, because of its capability of developing a strong bond with the bone tissue. However, its low mechanical strength does not allow applying it in places that support load. In addition to the high reactivity, an important requirement for its application is that the material must...

In the present work we attempt to describe the results of the thermal behavior analysis of a commercial glaze obtained in a thermal microscope developed by the research group. At the same time, the density and the wetting angle of the glaze with an alumina surface was evaluated. Particularly the sintering temperature, the sphere, semi-sphere and fu...

Three dimensional, highly porous, ZrO2 scaffolds coated by glass-ceramic derived from 45S5 bioglass were fabricated. The surface reactivity of 45S5 in aqueous solution was investigated as a function of the immersion time. The influence of the solid loading on the rheological behavior of 45S5 aqueous slips with ammonium polyacrylate (NH4PA) was stud...

Glass compositions were carefully prepared, using natural quartz and potassium feldspar as a part of the starting raw materials. The solids were prepared so as to have theoretical stoichiometric leucite and 45S5 Bioglass in different L/Bg weight ratios between 0.43-1.00. Novel bioactive glass-ceramics, containing leucite, sodium calcium silicate an...
