Non-isothermal sintering of powdered vitrified composites. A kinetic model
(Elsevier, 2019)
This report sets out the results obtained on studying the sintering process of glass–zircon composites,
analysing the microstructural changes that developed on modifying zircon content. The sintering of composites with ...
Sintered microstructure effect on RF-wave shielding properties of a Cu-doped Ni–Zn-polycrystalline ferrite
(Elsevier, 2021)
The shielding properties of a Cu-doped Ni–Zn polycrystalline ferrite in the frequency range 1 MHz to 1 GHz were explored. Samples of composition (Cu0.12Ni0.23Zn0.65)Fe2O4 were prepared by the traditional ceramic route. The ...
CuO improved (Sn,Sb)O2 ceramic anodes for electrochemical advanced oxidation processes
(American Ceramic Society, 2018-12)
Antimony‐doped tin oxide electrodes with CuO as sintering aid are presented as an economical alternative to metal‐based electrodes, intended for the electrooxidation process of emerging and recalcitrant organic contaminants ...
Beyond the energy balance: Exergy analysis of an industrial roller kiln firing porcelain tiles
(Elsevier, 2019-03)
The ceramic tile manufacturing process consumes large amounts of energy, mainly in the firing stage. Firing usually takes place in natural gas-fuelled continuous roller kilns, the most widely used tile firing facilities ...
Influence of microstructure and magnetizing mechanisms on magnetic complex permeability (imaginary part) of a Cu-doped Ni-Zn polycrystalline ferrite
(Elsevier, 2021)
The complex permeability of the Cu-doped Ni–Zn polycrystalline ferrites is strongly dependent on microstructure, particularly on relative density (ϕ) and average grain size (G), as it has been shown in a previous ...
An experimental study and computational validation of waste heat recovery from a lab scale ceramic kiln using a vertical multi-pass heat pipe heat exchanger
(Elsevier, 2020)
The development of waste heat recovery technologies has surged as a result of climate change initiatives, which require energy intensive industries to curb their emissions and lower energy consumption. Installing heat pipe ...
Low-cost ceramic membranes: A research opportunity for industrial application
(Elsevier, 2019-03)
Obtaining low-cost ceramic membranes has attracted great interest in the scientific community in last years, as it allows to preserve the advantages of ceramic materials while significantly reduce their manufacturing costs. ...
Residual stresses in porcelain tiles. Measurement and process variables assessment
(Elsevier, 2019-04-22)
This research addresses the residual stresses phenomenon taking place during the manufacture of porcelain tiles. Residual stresses were quantified by the strain relaxation slotting method. The method is based on the fact ...
Effect of feedstock and plasma gun on the microstructure and bioactivity of plasma sprayed bioactive glass coatings
(Elsevier, 2021-01-25)
Plasma–sprayed 45S5 bioactive glass coatings were manufactured using two types of powder
feedstocks (commercial and lab–made 45S5 glass) and two plasma torches (single and triple
cathode) to analyse their influence on ...
Single droplet drying of detergents: Experimentation and modelling
(ElsevierInstitute of Process EngineeringChinese Society of ParticuologyScience Press, 2021-03-03)
This study evaluates the single droplet drying (SDD) of detergents. Experimental data are used to validate a theoretical multistage model. The experiments are carried out in an acoustic levitator analysing six different ...
