Scientists from Perm National Research University of Technology in Russia have devised a way to produce ceramic filters whose pore opening can be controlled.
The university's media office said in a statement that ceramic filters, due to their porous structure, will be used to clean liquids and hot gases from microorganisms and soot, as well as from minerals and salts.
The method devised by the university's scientists is characterised by influencing the suspended solution using a permanently weak magnetic field during the casting process, a porous structure can be formed and the future material can be dried by additional freezing of the gel, the statement said, adding that the researchers determined the optimal conditions for this technology from the results of a series of experiments.
According to the scientists, this technology can be used to produce filters and catalysts in mechanical engineering, chemical and energy industries.
