Fabrication of ceramic materials with interconnected pores is necessary to improve thermal energy storage efficiency in high‐temperature infiltration technology. In the present study, industrial wastes such as coal gangue, steel slag, etc., were selected as the raw materials to prepare ceramics with interconnected pores. By adopting 50% cigarette butts as the pore‐forming agent, steel slag–coal gangue mixtures with a mass ratio of steel slag to coal gangue of 1:9 were sintered at 1100°C, and ceramics with interconnected elongated pores were prepared successfully. The highest apparent porosity and lowest volume density of the as‐prepared ceramics were ca. 73% and .74 g/cm3, respectively. Further measurements of the thermophysical properties indicated that no obvious mass loss was observed in the temperature range from ambient temperature to 800°C. The maximum values of specific heat and thermal conductivity were 1.38 J/(g K) and 1.661 W/(m K), respectively, and meanwhile the minimum compressive strength could exceed 3.5 MPa. These research results implied that the as‐prepared steel slag–coal gangue ceramics can provide long‐term service and offer excellent thermal stability over a wide temperature range. Therefore, they should have potential applications in high‐temperature infiltration technology.

“…For the burnout of pore formers, natural organic, or synthetic polymer particles are applied, that evaporate or burn during the sintering step of the ceramic material. This technique leads to pores of some micrometers up to some millimeters [ 4 , 5 ]. Porous ceramics, prepared by direct foaming via physical or chemical foaming mechanisms reach pore volumes up to 45–85% [ 6 ].…”

Alternative Process Routes to Manufacture Porous Ceramics—Opportunities and Challenges

Porous ceramics can be realized by different methods and are used for various applications such as cross-flow membranes or wall-flow filters, porous burners, solar receivers, structural design elements, or catalytic supports. Within this paper, three different alternative process routes are presented, which can be used to manufacture porous ceramic components with different properties or even graded porosity. The first process route is based on additive manufacturing (AM) of macro porous ceramic components. The second route is based on AM of a polymeric template, which is used to realize porous ceramic components via replica technique. The third process route is based on an AM technology, which allows the manufacturing of multimaterial or multiproperty ceramic components, like components with dense and porous volumes in one complex-shaped component.
