Optimization of the production process through response surface method: Bricks made of loess
(Elsevier, 2013)
Loess clays are commonly used to produce bricks. Heavy clays, taken at location near Zrenjanin, Serbia, are used as a representative raw material in this study. The sample, containing about 28% of clay sized particles, is ...
Shape and aspect ratio analysis of anisotropic magnetic nanochains based on TEM micrographs
(Ceramics International, 2018)
Due to advances in electron microscopy and to the development of novel nanoparticle structures with different morphologies and the dependence of physical properties on the nanoparticle morphology, there is a need for a ...
Influence of annealing treatment on magnetic properties of Fe2O3/SiO2 and formation of epsilon-Fe2O3 phase
(Ceramics International, 2017)
Magnetic properties of Fe2O3/SiO2 samples were studied after being produced by sol-gel synthesis and formation of epsilon-Fe2O3 polymorph. Samples were thermally treated, using different annealing temperatures and annealing ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...
Cyclic oxidation of Ti3Al-based materials
(Ceramics International, 2019)
The microstructure variation and oxidation behavior of a hot-rolled and quenched Ti-24Al-11Nb (at%) intermetallic alloy with and without protective Ni-20Cr (at%) coating were studied in the air at a cyclic annealing ...
Preparation of low cost alumina nanofibers via electrospinning of aluminium chloride hydroxide/poly (vinyl alcohol) solution
(Elsevier Sci Ltd, Oxford, 2013)
Alumina nanofibers are very suitable materials for use as reinforcement in a great variety of high performance composite materials. Nanosized alumina fibers were prepared from the aluminum chloride hydroxide/poly (vinyl ...
Crystallization and sinterability of glass-ceramics in the system La2O3-SrO-B2O3
(Elsevier Sci Ltd, Oxford, 2014)
Glasses with a constant B2O3 and an increasing La2O3 content in the system La2O3-SrO-B2O3 were obtained by the usual melt quenching procedure. The crystallization and sinterability of the glasses were investigated by hot ...
Preparation and characterization of poly(vinyl butyral) electrospun nanocomposite fibers reinforced with ultrasonically functionalized sepiolite
(Elsevier Sci Ltd, Oxford, 2014)
This study presents an investigation of the effects of the processing conditions on the uniformity, morphology and structure of patterned nanofibrous mats of electrospun poly(vinyl butyral)/sepiolite (PVB/Sep) nanocomposite ...
Spark plasma sintering of ZrC-SiC ceramics with LiYO2 additive
(Elsevier Sci Ltd, Oxford, 2013)
Spark plasma sintering (SPS) of ZrC-SiC composite powders in the presence of LiYO2 sintering additive was studied. The starting powders were obtained by a carbothermal reduction (CTR) of natural mineral zircon (ZrSiO4), ...
Lead immobilization by geopolymers based on mechanically activated fly ash
(Elsevier Sci Ltd, Oxford, 2014)
In this paper, the effectiveness of geopolymers based on initial and mechanically activated fly ash in immobilization of lead was investigated. Fly ash (FA) was firstly mechanically and then alkali activated at room ...
