Aerosol deposition method is a method to fabricate ceramic membranes, in which aerosol, or a mixture of fine ceramic particles with a diameter of around 1 micrometer and gas, is sprayed on a substance at a speed of around 150 to 400 m/sec to form membranes on it.
Typically, fabrication of ceramic membranes requires the ceramic materials, which are the ingredients of the membranes, and the object of membrane fabrication to be kept at a high temperature. In contrast, the aerosol deposition method can form membranes at room temperature, as it makes particles collide against a substance at a high speed and the resulting collision energy is used to form the membranes. This gives the method an advantage in that the object of membrane formation is not deteriorated by heat.
Research of this method has been under way over recent years, with the theme of reducing costs for practical applications.
