FIELD: various technological processes.
SUBSTANCE: invention relates to cleaning of hot gas from suspended particles, and more specifically to methods of producing ceramic filter elements, also known as "filter plug". Filter element is produced by firing target workpiece made from moulding mixture containing granular powder fraction and sintering powder fraction. Granular powder fraction used is silicon carbide powder. Sintered powder fraction is obtained by mixing talc, kaolin, alumina, pyrophyllite and lithium carbonate. Annealing of the target workpiece is carried out at temperature of 1,280–1,350 °C.
EFFECT: higher heat resistance of the filter element.
