Manufacture of oxy-acetylene thermally sprayed coating on refractory subtrates from unconventional feedstock material
(DYNA, 2018-04-01)
A chromite mineral and two industrial residues produced in the petrochemical and thermoelectric industries, were selected, characterized, processed and deposited on refractory bricks. By means of X-ray fluorescence and ...
Manufacturing of Photoactive β-Bismuth Oxide by Flame Spray Oxidation
(Journal of Thermal Spray Technology, 2021-03-21)
Photoactive tetragonal bismuth oxide powder with different semiconducting characteristics was synthesized from Bi-pellets by flame spray oxidation. The effect of feedstock particle size and standoff distance (SOD) on the ...
Microstructure, physical and mechanical properties of kaolin - diatomite composite reinforced with CaCO3
(DYNA, 2019-07-01)
The present work reports the microstructure, physical and mechanical properties of a material composed of kaolin, diatomite and calcium carbonate reinforcement (CaCO3). The ceramic prototypes were shaped by the slip casting ...
