Electroceramic devices

Figure 27.2 shows the photographs of sol-gel precursors and thin films prepared by CSD. This chapter presents a snapshot of the current status and key challenges in the field of electroceramic thin films processed by sol-gel. This chapter is mainly focused on metal oxide films, which are the most lucrative films prepared by CSD with the widest use in electroceramic devices. However, non-oxide materials have also been prepared by sol-gel and detailed overviews on them were reported by Kamiya [5,6], Fujihara [7], and Almeida and Xu [8].

It will be apparent from the contents page that the paragraph on electroceramics is one of the most elaborate of chapter 11 Seven Ceramic Branches of Industry. The main reason for this can be found in the large number of applications but also in the fact that the market for electroceramic materials is expected to grow considerably. This marktet, in its turn, is propelled by the strong desire to make electrical components of devices increasingly smaller. Table 11.4.1 shows a 2 thousand million dollar turnover for sophisticated electroceramic materials in Europe in 1995. It is expected that this amount will increase to approximately 3 thousand million in 2002.
