“…Porous silicon carbide (SiC) ceramics with low density, large specific surface area, excellent thermal shock and oxidation resistance, as well as high temperature and chemical corrosion resistance, are widely used as filter, thermal insulation, separation membranes, catalyst supports, bio-ceramics and other component materials. 1)3) So far, there are many preparation methods for porous SiC ceramics, including organic foam impregnation, 4) foaming, 5) adding pore-making agent, 6) solid-state sintering, 7) extrusion molding, 8) solgel, 9),10) and gelcasting. 11) The pore size of porous SiC ceramics prepared by organic foam impregnation mainly depends on the structural sizes of the pore and the coating thickness of the slurry.…”

“…11) The pore size of porous SiC ceramics prepared by organic foam impregnation mainly depends on the structural sizes of the pore and the coating thickness of the slurry. 4) The foaming reaction speed of foaming method is fast and a lot of gas is produced in a short time, which will produce large bubbles, blank collapse and nonuniform phenomenon, hence it is difficult to control the process conditions. 5) The method of adding pore-making agent can control the pores size, shape and porosity by adding poremaking agents with different shapes, particle sizes and contents.…”

With phenolic resin as carbon source, ethylene glycol as solvent and pore-forming agent, and silicon monoxide as pore-forming agent and silicon source, a kind of light hierarchical porous silicon carbide (SiC) ceramics with adjustable pores was prepared by gelcasting, carbonization and carbothermal reduction. With the addition of silicon monoxide in the green body from 13 to 49%, the porosities increased from 66 to 89%, the densities and thermal conductivity are as low as 0.36 g•cm ¹3 and 0.29 W•m ¹1 •K ¹1 . The macropores are mainly determined by the addition of silica particle size, which increases from 9.2 to 39.5%, while the micropores and mesopores, ranging from 56.8 to 49.5%, are mainly determined by the pyrolysis of resin carbon source. When the porosity of porous SiC is 75%, the compressive strength of 7.83 MPa can be reached. The prepared porous SiC ceramics possessed light, good thermal insulation and other properties, which can be further improved by changing the shape and size of the added SiO particles. In addition, different from using polycarbosilane as preceramic polymer, the porous SiC ceramics with complex shape and uniform microstructure can be prepared via gelcasting, which will reduce the production costs and broaden its application.

“…This binder is preferred because it is cheaper, environmentally friendly, and also has a better solubility [6]. M. Tange et al [7] used three different compositions of PVA as a binder which were 1 wt.%, 1.5 wt.% and 2 wt.% to produce titanium foam by sponge replication method. They found that the optimum PVA composition was 1.5 wt.%.…”

Biomaterials with a porous structure are beneficial for a wide range of medical engineering applications such as filtration, bone replacement and implant development. Stainless Steel 316L (SS316L) foam has been fabricated by foam replication method at different SS316L powder composition which is 60 wt%, 65 wt%, and 70 wt%. The binders used were Polyethylene Glycol (PEG), Carboxymethyl Cellulose (CMC) and Polyvinyl Alcohol (PVA), while distilled water was used as a solvent. The effects of using different composition of SS36L powd er, binders and sintering time to the SS316L foam properties was studied. The materials were mixed by usin g a mechanical stirrer at 250 rpm for 1 hour. Polyurethane foam (PU) which was used as a sacrificial template was dipped into the SS316L slurry until fully coated. The coated samples were then dried in a drying oven within 24 hours before being sintered in an argon gas environment at 1200C. The samples were characterized to observe the microstructure of the SS316L foam produced. As expected, the viscosity of the SS316L slurry was increased as the SS316L composition increases. The viscosity of SS316L slurry prepared by using PVA as a binder is higher than the SS316L slurry prepared with CMC and PEG as binder. The SS316L foam produced consisted of a larg e volume of open and interconnected pores especially at higher SS316L composition.
