Using high purity alumina and quartz powders and IG-017 bio-original additives of Igrex Ltd. the authors have developed new ceramic composite materials which can be applied in different industrial environment. 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. For this the mixed powders of Al2O3, SiO2 and IG-017 bio-original additive were uniaxially pressed at different compaction pressures into cylindrical shapes and were sintered in electric kiln under oxidation (1) and nitrogen (2) atmosphere. The grain size distribution of the raw materials was determined by laser granulometry. There thermo-physical properties were also determined by derivatography. The prepared and sintered specimens were tested on geometrical sizes, porosity and mechanical strength. In this work the authors present the results of their research and investigation.
