Title: FORMING METHOD OF INORGANIC PREFABRICATED MEMBER
Abstract:
A forming method of an inorganic prefabricated member, comprising the following steps: (1) adding short inorganic fibres or whiskers to a dispersing agent, and performing an ultrasonic treatment for uniformly dispersing same and forming a slurry; (2) uniformly soaking sponge in the slurry, so as to form a sponge containing the short inorganic fibres or whiskers by means of precipitation; and (3) placing the sponge containing the short inorganic fibres or whiskers in a high-temperature furnace in an oxidizing atmosphere, so as to remove polymers from the sponge by means of sintering coke exhaust and obtain the final ceramic prefabricated member. The ceramic prefabricated member containing the short inorganic fibres or whiskers obtained by the present method can be used for multiple purposes, such as permeable metal materials, etc.
