Utilization of diverse cheap materials as pore generating agent to manufacture low-cost porous ceramic

Abstract

Paper waste, corn starch, and sawdust were utilized as pore generating agents to produce a porous ceramic. Kaolin clay, sodium feldspar, and 20% of pore generating agent were mixed, and the samples were formed by mold method, dried at room temperature for about 72 h and in a furnace at 115 ºC for 5 h, and then fired at 1200 ºC with a soaking time of 3 h. The samples were tested for measurement of physical and mechanical properties and the microstructure was evaluated by scanning electron microscopy and mercury intrusion porosimetry. The results showed that the sample prepared with corn starch had the highest porosity, lowest mechanical properties and permeability, and smallest pore size, while the characteristics of the sample prepared with sawdust were contrary; finally, the sample of paper waste had the highest permeability and intermediate values of other properties.

Efek Penambahan Tepung Jagung Dalam Keramik Zeolit Sebagai Separator Baterai

“…Liu et al, 2022). Fabrikasi keramik berpori dengan menggunakan tepung jagung merupakan alternatif yang mudah dan murah (Nie & Lin, 2015;Salman et al, 2020). Kadar air yang ada dalam tepung jagung juga menguap membuat rongga-rongga pori.…”

The EU Training Network for Resource Recovery through Enhanced Landfill Mining—A Review

“…The crucial linkage between mineralogy and technical and environmental performance was also investigated in a further study in which low temperatures (800 • C) were sufficient to immobilize heavy metals in a stable matrix using spent borosilicate glasses and additional electromagnetic shielding functionalities were obtained by magnetite formation [146]. This approach was cited in a study on the substitution of feldspar by waste glass for porcelain production [147] and in a paper on cheap pore-generating agents for ceramics [148]. Finally, the promoting effect of firing in nitrogen atmosphere on the stabilization of pollutants and novel functionalities was investigated [149]; the paper was cited in studies on the recycling of iron-rich inorganic wastes into functional glass-ceramics [150] and on the production of glass ceramics from MSWI bottom ash and coal fly ash by melting and sintering [151].…”

Evaluating the properties of cellular ceramics prepared with a granite dust and plantain (Musa paradisiaca) peel powder for external wall thermal insulation of buildings

“…The utilization of cheap materials as pore-generating agents can facilitate the production of low-cost porous ceramics [16]. In this regard, Odewole and Folorunso [17] obtained porous ceramic from granite dust, clay, and sawdust and then suggested further research to evaluate the effectiveness of other organic additives.…”
