In this work was investigated the feasibility to use Waste Electrical and Electronic Equipment (WEEE) glasses in construction sector as secondary raw material. WEEE glasses were used in different percentages as a function of the product obtained: 30-40wt% for glaze formulations, about 40wt% for glass-ceramics and 5wt% in brick bodies. The laboratory and industrial scale up results demonstrated ...

In the work using finite element method, an analysis of behavior nose fairings made radio-transparent ceramic materials celsian composition was carried out. Determination parameters gas dynamics and stress-strain state out licensed ANSYS software. SSG Reynold Stress turbulence model chosen for accurate air flow simulation. Geometric models were used to calculate strength temperature fields. The...

BaO -SiO2-Al2O3 glass ceramics containing K2O and B2O3 were prepared using conventional melting of powered batches, quenching in water and crystallization of sintered glass. XRD patterns introducehexacelsian and celsian as two major crystallized phases in sintered glass-ceramics. Presence of K2O enhances crystallization of hexacelsianin comparison withB2O3.Observations showed sintering temperat...

The article examines the effect of additives on intensification sintering process ceramic materials based BaO – Al2O3 SiO2 system. Taking into account different mechanisms interaction with main matrix, modifiers MgO, Cr2O3, ZrSiO4, TiO2 and mineralizers CaCO3, B2O3, MoO3, SnO2 : Li2O were selected for research. On basis conducted complex studies, it was established that most promising intensifi...

This paper presents a comparative analysis of microstructural parameters by the powder X-ray diffraction method on polycrystalline sample and fractal analysis. The presented results are obtained crystallographic programs FullProf based Rietveld method. synthetic Ba/Ca-celsian has been used for feldspar synthesized thermal induction phase transformation process ion exchange Ca-LTA zeolite with B...
