The non-isochemical crystallization of glasses leads to glass-ceramics in which the chemical composition of the amorphous matrix differs from that of the parent glass. It is challenging to solely analyse the properties of these residual glassy phases because they frequently contain finely dispersed crystals. In this study, the composition of the residual glass matrix after the crystallization o...

An exo-templating synthesis process using polymeric fibers and inorganic sol particles deposited onto structured one-dimensional objects is presented. In particular, CeO2/ZrO2@SiO2 composite tubes were synthesized in a two-step procedure by using electrospun polystyrene fibers as fiber template. First, a sol-gel approach based on an exo-templating technique was employed to obtain polystyrene(PS...

W-Si-C composites with high relative densities and good mechanical wear properties were successfully prepared by spark plasma sintering. The influence of SiC content on the density, microstructure, characteristics was investigated. results indicated that reaction between W at their interface produced W2C W5Si3. also reacted oxygen impurities grain boundary to form SiO2. purification boundaries ...

Lithium aluminum silicate (LAS, Li2O-Al2O3-SiO2) glass-ceramics have been employed in dentistry as substitutes while seldom orthopaedics. This is primarily due to difficulties with balancing the biomechanical and biological performance. study aims investigate effects of SiO2 content thermal treatment on formation Li2SiO3, Li2Si2O5 LiAlSi2O6 LAS glass-ceramics, these crystalline phases The prepa...

Expansive soils have high compressibility, swelling, and shrinkage properties. So we need an effective method to improve soil conditions when the structure is built on it. This paper presents results of research effect substitution ceramic waste physical properties expansive soil. Soil improvement using construction will contribute reducing amount conserving natural resources. The stages includ...

In this work, an aerodynamic levitation technology (ALT) was utilized to prepare ZrO2-SiO2 glass-ceramics with two different ZrO2 contents, that is, 35 mol% and 50 mol%. The were partially melted at ∼2000°C or fully ∼3000°C by ALT, followed rapid quenching obtain spherical glass-ceramic beads. phase compositions microstructures of the characterized. Crystallization occurred during solidificatio...

SiO2 has been extensively studied as a superior insulating layer for innovative Fe-based soft magnetic composites (SMCs). During the preparation process of SMCs, appropriate heat treatment can effectively alleviate internal stress, reduce dislocation density, decrease coercivity, and enhance permeability. Maintaining uniformity integrity layers during is challenging task. Hence, it crucial to e...

Among different silicate systems, CaO−MgO−SiO2 is the one of most promising due to abundance reagents, easier fabrication, improved performance, and wide range application. Analysis current literature sources denotes that phase diagram system regularly used by researchers worldwide as constitutive model for synthesis glass-ceramic materials (GCs) possessing an adequate combination high chemical...
