Sažetak
Different methods have been used to produce porous ceramics for various applications. The generation of pores in ceramic samples offers a new range of different properties. Moreover, that porosity can be achieved using all kinds of various waste such as industrial, agricultural, domestic etc. One example being the process of coffee brewing which produces a large amount of waste, that was therefore used as a pore-forming agent in the production of porous ceramics. Suspensions of 60 wt.% alumina with different amount of waste coffee grounds were prepared. Viscosity of all suspensions was determined by means of rotational viscometer. Green bodies were prepared by slip casting in plaster mold. DTA/TGA analysis of waste coffee grounds revealed multistep endothermic and exothermic events related with release and burning of the precursor materials accompanied with mass loss. The sintering regime was determined according to the DTA/TGA analysis of thermal decomposition of waste coffee grounds. Density of the obtained sintered samples was investigated and calculated.
