Institute of Inorganic Chemistry, Slovak Academy of Sciences, Dúbravská cesta 9, SK-842 36 Bratislava, Slovakia

Abstract: This paper deals with the role of chemistry in the design of high-tech ceramic materials. Grain boundary composition of polycrystalline ceramics dictates the hardness fracture toughness and creep resistance of liquid-phase sintered silicon nitride and silicon carbide materials.
