Metal alkoxides are relatively larger molecules consisting of a metal ion surrounded by a number of organic alkoxide groups. During sol synthesis, the metal-organic precursors undergo hydrolysis and condensation reactions to build up the 3D nanoscale metal-organic clusters. During hydrolysis reactions, the metal alkoxides become partially hydrolyzed by reacting with water to replace one or more of the alkoxide side groups. Condensation reaction can then take place, leading to the polymerization of these partially hydrolyzed metal alkoxides and the release of water and alcohol.
Higher levels of energy can be captured by making use of the bending motion induced by thermal expansion mismatches between the pyroelectric material and the substrate. While driven by a changing temperature, power is generated via the piezoelectric effect. 4 Other functional devices There are a host of other functional ceramics that can be incorporated into microsystems in a similar way to piezoelectric materials. The structures adopted are often based on the same basic structure with electrical connections to the functional ceramic, in order to transmit the resultant signal or power, which is placed on a supporting substrate.
Not only does the sintering aid increase the rate of diffusion, it also acts as a lubricant which, in the very early stages of sintering, allows the powder particles to rearrange themselves into more favorable packing structure. This increases grain-on-grain contact and can also increase the green density of the ceramic, meaning that the total amount densification required on sintering is reduced. 1 provides some examples of liquid-phase sintering aids and the typical quantities added. 3 Thick-film powder-based routes 45 Relatively high levels of sintering aids can be used, as in the case of lead borosilicate glass where up to 30 vol% is added to bind the active ceramic particles together and to the substrate.
