Processing Techniques

Conventional thin-film processing techniques remain inadequate for obtaining superior dense ceramic thick films. The incompatibility of ceramic films prepared via other methods, such as screen printing, spin coating, and sputtering, is a major obstacle in the fabrication of thick film-based ceramic electronic components. The granule spray in vacuum (GSV) processes and aerosol deposition (AD) are important coating approaches for forming dense ceramic thick films featuring nanoscale crystallite structures at room temperature, which offer excellent material properties and facilitate cost-effective production. AD ceramic coatings require the acceleration of solid-state submicron ceramic particles via gas streams with a velocity of a few hundred meters per second, which are then wedged onto a substrate. This process is economical and particularly useful for the fabrication of piezoelectric thick film-based microactuators, energy harvesters, sensors, and optoelectronic devices. More recently, the GSV technique was improved to achieve more uniform and homogeneous film deposition after AD. This review article presents a detailed overview of the AD and GSV processes for piezoelectric thick films in terms of recent scientific and technological applications.

Functional Ceramics

The Aerosol Deposition (AD) method is a dry spray coating process for the production of dense ceramic coatings at room temperature directly from the ceramic raw powder. In order to avoid confusion with liquid aerosol technology, the term powder aerosol deposition (PAD) is introduced here, to highlight that the aerosol consists only of ceramic powder and carrier gas. Especially in the field of functional ceramics, PAD is a promising alternative to conventional sinter-based production processes. This review focuses on the PAD of functional ceramics in the field of sensing and energy technology. In this context, especially current developments and trends are presented. On the part of the sensors, gas and temperature sensors are especially considered, whereas in the field of energy technology, the focus is on vibration energy harvesting, thermoelectric generators, superconductors, and solar cells as well as on all solid-state batteries and fuel cells. Besides the different applications of PAD films, this review also highlights opportunities for influencing the film properties by the used powder or the process parameters.

This work shows that the powder aerosol deposition (PAD) method allows the formation of films in powder quantities of less than 60 mg, rather than the large amounts that are typically required for conventional powder aerosol deposition systems. This was achieved by changing the operation mode to a discontinuous one, resulting in operation times of several seconds. Semiconducting strontium titanate ferrate SrTi0.65Fe0.35O3−δ (STF35) was used as the powder to prove the equal behavior in terms of adhesion, film quality and electric conductivity compared to conventional powder-aerosol-deposited films.
