“…• The idea of coating of ferritic steel to hinder permeation of tritium from liquid Pb-17Li breeder and plasma into water/helium coolant in a test blanket module initiated a study of sol-gel alumina coating performance on steel ). • Decrease of hydrogen damage to Pb(Zr,Ti)O 3 being part of sensors and actuators operating on hydrogen-containing atmosphere by coating with an aqueous sol prepared from commercial boehmite powder (Shafiei et al 2013). • Preparation of coatings on lithium containing mixed oxides used as highperformance cathode materials for lithium batteries (Liu et al 2002;Xu et al 2015).…”

This chapter gives an overview over preparation, properties, and applications of alumina thin films. The preparation of polymeric and colloidal alumina sols and their deposition on diverse substrate materials with different geometries are described first. Consideration of properties (surface tension, particle size, viscosity, aging of the sols, and their optimization by using certain additives) is included, too. A description of posttreatments of the coatings, which initiate phase transformations and also determine their microstructure, completes the part on coating preparation. Data on adhesion, thickness, surface roughness, and mechanical, textural as well as optical properties of alumina thin films are provided in a further paragraph. In a third main part, experience concerning possible applications, such as (i) membranes for catalysis, separation, and filtration, (ii) barrier layers against electrochemical and high-temperature corrosion or interdiffusion of ions between different phases, (iii) mechanical protection, (iv) sensor construction, (v) improvement of optical properties, as well as (vi) achieving water repellency, is summarized.
