“…It is known that the characteristics are determined by the quality of source ceramic powder (particle shape, particle size distribution) [7,8], the conditions of compacting and sintering modes [9,10] and any features that are presented in each phase, and how these phases, including pores, are arranged in relation to each other [11]. The most important factor in the successful application of materials is the understanding of the features of a structure emerging in them on their behavior under mechanical impact [12].…”

Porous ceramics have been studied obtained from ultra-fine zro 2 powders. the porosity of ceramic samples was from 15 to 80%. the structure of the ceramic materials was a cellular structure. A distinctive feature of all the deformation diagrams obtained in the experiment was their nonlinearity at low deformations which was described by the parabolic law. it was shown that the observed nonlinear elasticity for low deformations on deformation diagrams is due to mechanical instability of the cellular elements in the ceramic carcass.

Kowi or crucibles come from refractory materials. This study aims to determine the effect of the powder particle size of evaporation boats on impact resistance and macro structure. The research method used is experimental research. The variation applied was a variation of the particle size of the evaporation boats (80, 100, and 120 mesh) as much as 50% (grams) mixed with 25% (gram), kaolin, and 25% (gram) mortar. The mixture of these ingredients is added 15% (grams) of water from the total weight of the mixture. Mixing using a mixer for 1 hour and adding water. Then the material is put into a specimen mold with ASTM D256 standards and compacted at 60kg/cm2 using a hydraulic press. Sintering at 1000˚C was carried out using an oven with a heating rate of 5˚C / minute and a holding time of 2 hours. The highest impact price on average of 0.002828936 Joule/mm2 was obtained for the use of mesh 120 evaporation boats particle size and the lowest average impact price of 0.002633081 Joule / mm2 was obtained for the use of mesh 80 evaporation boats powder particle size. The macro structure of firing results and the best density is obtained from the use of the mesh 120 and 100 evaporation boats particle size and a fracture occurs on the flatter surface of the specimen than 80 and 100 evaporation boats mesh.

“…Porosity of ceramic played such a crucial rules which determine the hardness and strength of a ceramic. To reduce the formation of porous cordierite, the addition of sintering aids or nucleating agent are essential to avoid a grain growth [5] due to high sintering temperature as it can consolidate the cordierite ceramic at low sintering temperature.Thus, the sintering aids is essential additives in cordierite synthesis. Magnesium oxide or zirconia are the other example of sintering aids can be used in synthesis cordierite [6].…”

The effects of addition treated FGD sludge in non-stoichiometric cordierite, by benefiting from its high mechanical strength and good thermal performance, can hold promise for more practical applications of non-stoichiometric cordierite. Treated FGD sludge waste from borosilicate glass industrial were used as a flux to reduce the sintering temperature of cordierite. Cordierite ceramics were prepared using silica (SiO2), alumina (Al2O3), talc, kaolin, magnesia (MgO) and treated FGD sludge via solid-state reaction method. The cordierite were prepared by adjusting the ratio of FGD sludge and magnesia in the cordierite composition, respectively. 4 composition of cordierite with 0%, 1.5%, 3.0% and 4.5% of FGD sludge were prepared to obtain the formation of α-cordierite that can be determine by X-ray diffraction (XRD) analysis. Porosity, density, shrinkage and flexural strength for each of cordierite composition were determined to obtain the best composition of treated FGD sludge required for sintering aids of cordierite. Only FGD 3.0% able to synthesis pure α-cordierite while FGD 1.5 % shows an improvement in both porosity and density. The increasing amount of treated FGD sludge lead to decreasing in mechanical strength of cordierite ceramic due to porous formation.
