Fabrication of Porous Anorthite Ceramic Insulation Using Solid Wastes

Materials (2024)

Mia Omerašević Vladimir Pavkov Milena Rosić Marija Egerić Snežana Nenadović

Porous anorthite (CaAl2Si2O8) ceramics, suitable for thermal insulation in buildings, were obtained using waste seashells as a source of CaO, kaolin as a source of Al2O3 and SiO2 and banana peel as a pore former. Changing the volume of banana peel as well as the processing temperature was found to be an effective approach to control the thermo-mechanical properties of the obtained anorthite ceramics. The sintering of powder compacts containing up to 30 wt% banana peel at temperatures ranging from 1100 to 1200 °C resulted in anorthite ceramics possessing up to 45% open porosity, a compressive strength between 13 and 92 MPa, a bulk density between 1.87 and 2.62 g/cm3 and thermal conductivity between 0.097 and 3.5 W/mK. It was shown that waste materials such as seashells and banana peel can be used to obtain cost-effective thermal insulation in buildings.

Synthesis and settings behavior of α-TCP from calcium deficient hyroxyapatite obtained by hydrothermal method

Journal of Optoelectronics and Advanced Materials (2007)

Bojan Jokić Ivona Janković‐Častvan Djordje Veljović Dušan Bučevac Kosovka Obradović-Djuričić

The aim of this work is the investigation of alpha-tricalcium-phosphate (a-TCP) formation from calcium-deficient hydroxyapatite (CDHAP), synthesized by hydrothermal method from CaCl 2 , EDTA, NaH 2 PO 4 ·2H 2 O and urea as precursors at 160 °C. Further, the influence of Ca/P ratios in the starting solution on α-TCP formation and the settings of obtained cements in simulated body fluid (SBF) were investigated. According to the results of X-ray, FTIR and SEM analyses, it is shown that CDHAP is transformed to β-TCP ai 800 °C, and to α-TCP at 1200 °C. Almost complete transformation of CDHAP into α-TCP occur after heating at 1500 °C in the case when Ca/P ratio in starting solution was 1,42. Cement powder mixed with the cement liquid (2.5 wt.% solution of Na 2 HPO 4 ) completely hydrolyzes after 7 days in SBF, forming only CDHAP phase.

Synthesis and Characterization of Hafnium Carbide Based Ceramics

Key engineering materials (2014)

Branko Matović Dušan Bučevac Vesna Maksimović Snežana Nenadović Jelena Pantić

Hafnium carbide powder was synthesized by sol-gel polycondensation of hafnium chloride with citric acid. The starting materials were dissolved in water and mixed homogeneously on a hot plate until a precomposite gel was formed. Pyrolysis of the obtained gel resulted in formation of monoclinic hafnia and amorphous carbon, which after subsequent heat treatment transformed into hafnium carbide. Materials were analyzed by means of X-ray diffraction and electron microscopy investigations. The results showed that the obtained carbide powder was composed of nearly equiaxed particles of narrow size distribution. The obtained hafnium carbide powder was densified via spark plasma sintering (SPS) at 1950 oC using molybdenun silicide as sintering additive. Microstructure and mechanical properties of the obtained hafnium carbide ceramics were investigated.
