Influence of the Composition and Properties of Molding Bodies on the Characteristics of Corundum Block Carriers

Аннотация

Extrusion molding, varying the particle size and the conditions for obtaining corundum, was used to obtain ceramic block carriers. The structural and mechanical properties of the molding bodies were investigated, and the textural and strength characteristics of the blocks after calcination were determined. It was shown that the use of corundum powder obtained by mixing particles of different size results in the production of molding bodies of the first or fourth structural-mechanical type and makes it possible to produce ceramic block carrier with channel density about 200 pieces/inch², mechanical strength at least 4.3 MPa, and high resistance to thermal cycling.
