Sago starch as binder and pore-forming agent for the fabrication of porcelain foam

Porous ceramic materials by pore-forming agent method: An intermingled fractal units analysis and procedure to predict thermal conductivity

“…One of the most pore-forming agent used is starch [13][14][15], but its application is limited to the production of large pores (5-50 μm) [9]. A good alternative is represented by polymers.…”

Fabrication of porcelain foam substrates coated with SiC, Ni, and Cr using the dip-coating technique

“…Several studies have suggested the use of thick coating or secondary coating as solution to overcome this problem [15,23,24]. 8 No significant weight change was observed during the initial test for the sponge as presented in [25]. However, it started to decompose in a two-step manner with an obvious steep decrease at approximately 250-330 ºC due to the decomposition of urethane bonds; the second decrease happened between 350 ºC and 420 ºC, attributed to loss of ester groups [26].…”

“…The sponge used was similar to the one used in our previous study[25].The sponge template inFig. 2(a)represents the sponge characteristics before the replication and sintering process.…”

The effect of sago as binder in the fabrication of alumina foam through the polymeric sponge replication technique

“…28 Previously, sago was compared with commercial synthetic binder (PVA) in the fabrication of porcelain foam. 15 Therefore, an idea to improve the strength of alumina foam by incorporation of sago binder was proposed in this paper. Furthermore, the effect of sago in the fabrication of alumina foam is not widely explored.…”
