Abstract
In accordance with the invention there are devices and processes for making ceramic nanofiber mats and ceramic filters for use in high temperature and in corrosive environments. The process for forming a ceramic filter can include electrospinning a preceramic polymer solution into a preceramic polymer fiber having a diameter from about 10 nm to about 1 micron and forming a preceramic polymer fiber web from the preceramic polymer fiber onto a collector. The process can also include pyrolyzing the preceramic polymer fiber web to form a ceramic nanofiber mat having a diameter less than the diameter of the preceramic polymer fiber, the ceramic nanofiber mat comprising one or more of an oxide ceramic and a non-oxide ceramic such that the ceramic fiber mat can withstand temperature greater than about 1000 ° C.
