John Hugh Chesters, fulfilling his ambitions as a schoolboy, had a lifelong involvement in the application of science to solve practical and industrially important problems. His major contributions relate mainly to the efficiency and reliability of furnaces for steel melting. These were accomplished through research on refractory materials for furnace linings and on heat flow. His work led to great improvements in the processing and use of ceramics in bulk and in the characterization of the structure and properties of these materials. As a result, the capability of appropriate refractory materials to withstand stresses, sudden thermal shock, and corrosive environments for the long periods at high temperatures that arise in iron and steelmaking processes was substantially increased.

Refractory Materials

Mechanical tests provide important information about the properties and behaviour of materials. Basic tests include the measurement of flexural strength and in case of refractory materials, the measurement of flexural strength at high temperatures as well. The dependence of flexural strength on the temperature of ceramic materials usually exhibits a constant progression up to a certain temperature, where the material starts to melt and so the curve begins to decline. However, it was discovered that ceramic mullitic material with a 63 wt.% of Al2O3 exhibits a relatively significant maximum level of flexural strength at about 1000?C and refractory mullitic material with a 60 wt.% of Al2O3 also exhibits a similar maximum level at about 1100?C. The mentioned maximum is easily reproducible, but it has no connection with the usual changes in structure of material during heating. The maximum was also identified by another measurement, for example from the progression of the dynamic Young?s modulus or from deflection curves. The aim of this work was to analyse and explain the reason for the flexural strength maximum of mullitic materials at high temperatures.

ABSTRACTTwo refractory material systems show promise for efficient energy conversion at high temperatures (>1000 K): the rare-earth chalcogenides and the boron-rich borides. The electronic and thermal transport properties of these two systems are compared and discussed.
