AUTOMOTIVE CERAMICS

advanced ceramic materials that are made into components for automobiles. Examples include spark plug insulators, catalysts and catalyst supports for emission control devices, and sensors of various kinds. This article briefly describes two important automotive applications of modern advanced ceramicssupport structures for catalytic converter elements and various pressure and heat sensors. Additional reading Specific information on automotive ceramics is provided in the article by L.H. Van Vlack, Automotive Materials, in R.J. Brook, Robert W. Cahn, and Michael B. Bever (eds.), Concise Encyclopedia of Advanced Ceramic Material (1991), pp. 2530; and two subsections in Theodore J. Reinhart (ed.), Engineered Materials Handbook, vol. 4, Ceramics and Glasses, ed. by Samuel J. Schneider (1991): Ray Kamo, Adiabatic Diesel Engines, pp. 987994; and Jay R. Smyth, Advanced Gas Turbines, pp. 9951002. The section titled Structural Applications for Technical, Engineering, and Advanced Ceramics, pp. 9591014 in the Reinhart work cited above, presents an overview of advanced structural ceramics.
