Abstract
There is provided a method for production of ceramic fibers that have small fiber diameters and adequate photocatalytic activity even when exposed to high-temperature environments, the method providing cost advantages and a safe production environment. Specifically, a composition containing titanium atoms, silicon atoms and aluminum atoms is used for production of a fiber aggregate from the composition by electrospinning, followed by calcination to obtain ceramic fiber with a mean fiber diameter of between 50 nm and 1000 nm.
Claims11
A ceramic fiber with photocatalytic activity,
- composed of an oxide ceramic containing titanium atoms, silicon atoms and aluminum atoms, and
- having a mean fiber diameter of between 50 nm and 1000 nm.
A method for production of a ceramic fiber that comprises
- a fiber-forming composition preparation step in which a fiber-forming composition containing a titanium compound, silicon compound, aluminum compound, water and a fiber-forming substance is prepared,
- a spinning step in which the fiber-forming composition is ejected by an electrospinning process to obtain fiber,
- an accumulation step in which the fiber is accumulated to obtain a fiber aggregate, and
- a calcination step in which the fiber aggregate is fired to obtain a fiber structure.
