“…The size of potato starch used in this research is around 15.78 µm. Based on the peaks found in the XRD results on the local filter, the phase owned by each local composition filter is mullite, characterized by the presence of Oksigen, Aluminum, and Silicon elements shown by EDS results [17]. The formation of the mullite phase in the local holder and filter means that the kaolin base material will form a mullite phase when burned to a temperature of 1200°C.…”

Research on ceramic filters, needed in the aluminum casting industry because of their ability to filter inclusions, has been done. This study's primary material to make ceramic or local filters is kaolin. The manufacture of local filters in this study uses the dry press method. In this study, potato starch with a composition of 5%, 10%, and 15% acted as a pore-former in the local filter. The local filter burned to a temperature of about 1200°C to obtain the mullite phase. Local filter characterization used SEM, XRD, XRF, and DTA. Several tests were carried out in this study, including Permanent Linear Change (PLC) test, thermal expansion test, flexural strength test, and porosity test. The results obtained in this study show that pores on the local filter are not open, have a prolate shape, and have an average pore size of 10 to 55 m. Burning kaolin up to 1200°C proved successful in obtaining the mullite phase. Another result of this study, the more starch content added to the material, the greater the shrinkage and expansion of the material; the highest shrinkage value on the material is 0.17%, and the highest expansion value of the material is 0,29%, the 15% values owned by potato starch. It is different in the flexural strength value, which has the highest value with 0% potato starch at 14.14 MPa and the lowest value with 15% potato starch at 5.39 MPa.

“…The relevance of studying the interphase interaction, which determines the main technological properties of nanocomposites (other nanostructures) based on aluminosilicate raw materials in the course of synthesis processes, is extremely high. Potentially available, and also used practically today, aluminosilicate components for the synthesis (production) of industrially significant products are classified into 3 categories: technogenic, synthetic and natural [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The diversity and prevalence of aluminosilicates makes them promising test objects.…”

“…From the synthesis of prebiotic organic molecules to modern weathering reactions, to implants in the human body, the interaction of organic species with mineral surfaces in the environment plays an important role. Intersurface reactions include responses to environmental disturbances such as changes in T and P, radiation and physical fields, ionic strength, and surface coating [15,[18][19][20][21][22][23][24][25][26][27][28][29][30].…”

“…We also observe that different products are formed at different temperatures and pressures, which suggests that the boundary is not the only chemical reaction [18][19][20][21][22][23][24][25][26][27][28][29][30]. If we understand the behavior of these parameters, it will be possible to assess the effect of aluminosilicates associated with primitive planetary material on the reaction in various applied tasks.…”

The scientific basis for the development of innovative materials (microporous, nanostructured, composite) based on natural (technogenic and synthetic) aluminosilicate raw materials determine prototypes of new technologies in modern industry. Inspired by this, we studied interphase boundary interactions of the “aluminosicate resource – nanoproduct” type system as a key factor of aggregation and nanostructuring in the processes of mineral formation and synthesis. To study features of the heterogeneity of the structure and their correlations with the thermodynamic parameters of the formation of mineral aggregates and individuals, instrumental and methodological resources were used. Based on previous and current studies of natural, synthesized and technogenic aluminosilicates (zeolites, clays, halloysite, fly ash, halloysite nanotubes, etc., features of the constitution and surfaces, sorption, ion-exchange, catalytic, –QS and +QS, biocompatibility, nontoxicity and other useful properties) the prospects for promotion of their industrial application were considered.

“…Kaolinitic materials have acquired an increasing importance by the use of ceramics in new industrial applications [1,2] in addition to the classical uses. Determining the optimal firing temperature for a clay is essential to produce quality ceramics to use not more energy than is strictly necessary, thus the mechanical properties of the fired clays deepen on these temperatures [3,4].…”

The thermal properties and evolution of mineralogy and colour of kaolinitic clay from the Terra Alta region were studied. The mineralogy of these materials consists mainly of kaolinite (13–27 mass%) and quartz (48–86 mass%). Minor illite, hematite, K-feldspar and calcite also occur. The linear expansion and absorption curves were used to predict the optimal firing temperature of the raw clays. During firing, from 1100 °C the water absorption decreases steeply, due to an increase in liquid phase, which penetrates into the pores and close the porosity. At this temperature, the firing shrinkage increases progressively. The fired clays are mainly composed of quartz, cristobalite and mullite, with minor hematite and rutile. Mullite starts to appear at 1050–1100 °C. SEM observations show that porosity decreases with the firing temperature. The colour properties were measured in the raw clays and in the fired bricks at different temperatures. The lightness, L*, is lower in the fired test pieces respect to the natural clays. This colour varies according to the hematite content, being from white to reddish in the fired samples.
