Efficiency And Reliability

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.

Phenolic Composite

A method of adding RAM directly in silica phenolic composite was tested. Due to direct incorporation of RAM, the resultant composite not only can show microwave absorption at normal conditions but can sustain this capability at high heat fluxes. Such RAM added composite becomes more applicable for materials which are exposed to high temperatures. Two different RAM added silica fibre phenolic composites were developed and their RF-absorptions were compared with pure silica fibre phenolic sample. It was found that depending on the type of RAM their RF-absorption can be enhanced. Strength and ablation properties of the resultant composites were also found to alter with the addition of RAM in the composite.

The new perovskite (Bi0.5Sr0.5)(Co0.5Ru0.5)O3 has been prepared under high pressure (10 GPa) and temperature (900 °C). The room-temperature crystal structure is described by the space group Pnma (a = 5.5702(3), b = 7.8793(5) and c = 5.5599(4) Å ) with no observed order between Bi and Sr or between Co and Ru cations. This material shows antiferromagnetic spin ordering or freezing below 50 K and a paramagnetic moment of 4.07 μB per formula unit at high temperatures, consistent with the presence of high-spin Co2+ or Co3+ ions. (Bi0.5Sr0.5)(Co0.5Ru0.5)O3 is a variable range hopping semiconductor between 40 and 300 K with a small negative magnetoresistance.
