Development of High-tech Ceramic Composites From Conventional Kaolinite Minerals and IG-017 Additives

Abstract

Based on conventional kaolinite and IG-017 bio-original additives of IGREX Ltd. the authors have developed new ceramic composite materials for different industrial purposes. For this the mixed powders of kaolinite and IG-017 bio-original additive were milled and uniaxially pressed at different compaction pressures into cylindrical shapes and were sintered in electric kiln under oxidation atmosphere (1) and by IGREX-Know-How (2). Using the IGREX-Know-How of sintering new high porosity material compositions with carbon and silicon carbide particles were created in the microstructures of the produced specimens. The grain size distribution of the raw materials was determined by laser granulometry and the thermo-physical properties by derivatography. The prepared and sintered specimens were tested on geometrical sizes, microstructures and morphologies by scanning electron microscopy. In this work the authors presents some parts of the results of their research and investigation.

Effect of Silica Particle Size on the Physical and Mechanical Properties of Lightweight Ceramic Composites

“…The main problem has been to produce materials having both good strength and a high level of porosity [5,6]. As in other brittle materials, the attainable strength is generally determined by the pore sizes and their distributions [7].…”
