“…The geometrical parameters of the ceramic products are strongly depending on the material compositions and sintering conditions, like temperature, and sintering environment [5], [20], [21]. Due to sintering in different atmospheres, the colour of the ceramic specimens has changed as shown in Fig.…”

Ceramics reinforced with carbon and silicon carbide particles are of great importance in the field of technical ceramics and ceramic composites. In this research, the possibilities of producing advanced ceramics from traditional, relatively inexpensive materials were studied. The authors have successfully developed mullite ceramic materials reinforced with carbon particles using kaolinite powder and sawdust. Powder mixtures with different compositions were prepared in a planetary ball mill using silica balls. The produced mixtures were compacted in a 100 kN pull-press to produce pellets using a pressure of 140 MPa. The prepared specimens were sintered in a laboratory chamber kiln under oxygen deficient conditions at 1250°C. After sintering of the specimens, considerable amounts of carbon content were incorporated into the material structure of produced ceramics, which were confirmed by energy-dispersive X-ray analysis. Using 10-20 m% sawdust in the mixtures, the carbon (C) content of sintered specimens was found to be more than 8 m%.

“…It is well known from practice that during sintering the Al 2 O 3 -SiO 2 ceramics items are shrinking and this shrinkage very strong depends on firing conditions and temperature [20][21][22][23]. Our experiments confirmed that the geometrical parameters of the pre-sintered ceramic items strong depend not only on the material compositions but on sintering conditions, including temperatures, pressures and atmospherically environments, thanking to the chemical reactions and phase transformations in solid stages and gasification or degasification of volatile component (Figure 3).…”

Based on high purity alumina and quartz powders and IG-017 bio-original additives the authors have developed new ceramic composite materials for different industrial purposes. The main goal was to fine a material and morphological structures of high performance ceramic composites as frames for development complex materials for extreme consumptions in the future. For this the mixed powders of Al 2 O 3 , SiO 2 and IG-017 bio-original additive were uniaxially pressed at different compaction pressures into disc shapes and were sintered in electric kiln under air (1) and nitrogrn (2) atmosphere. The grain size distributions of the raw materials were determined by laser granulometry. There thermo-physical properties were also determined by derivatography.The prepared and sintered specimens were tested on geometrical sizes, microstructure and morphology by scanning electron microscopy, porosity and water absorption. In this work the authors present the results of their research and investigation.

“…Clays are used also more than 7,000 years [2] to prepare building materials. In spite of the clay minerals are used by thousand years their study and examination are in the focus of research in several segments of science [3][4][5][6][7][8][9][10] and industry [11][12][13][14][15][16][17][18] until today. In our days the brick and ceramic roof tiles industries are the largest user of the conventional brick clays [19][20][21][22][23][24][25][26][27][28][29].…”
