“…The pore size, according to International Union of Pure and Applied Chemistry (IUPAC) 2 can be classified as micro (<2 nm), meso (2-50 nm) or macropores (>50 nm). The distribution and amount of pores determine specific properties, such as low density and thermal conductivity, high surface area, permeability and chemical and thermal stability 1,4,5 . Furthermore, glass foams have mechanical strength and chemical and thermal stabilities greater than the polymeric foams typically employed in such cases 1,6,7 .…”

“…Cerâmicas celulares são materiais de baixa densidade que apresentam células fechadas ou abertas 1 . O crescente interesse em cerâmi-cas celulares tem sido associado principalmente a suas propriedades específicas, como alta área superficial, alta permeabilidade, baixa densidade, baixa condutividade térmica, juntamente com as característi-cas próprias dos materiais cerâmicos, alta refratariedade e resistência a ataques químicos.…”

“…However, it is difficult to realize high open porosities by conventional methods because of insufficient control of interconnection among cells. Therefore, many researchers have been studied and reported various preparation methods, such as pore-forming procedures [8][9][10], a polymeric sponge replication [11][12][13][14], a gel-casting [15][16][17], preceramic polymers [18,19], template [20][21][22][23] and sol-gel methods [24], in order to achieve high open porosity and well-ordered porous structure. Among them, Kim et al have succeeded in preparing well-ordered porous ceramics (mean pore size: ca.…”
