Abstract
A method of making a permeable fiber-reinforced ceramic body comprising mixing an organic particulate with silica fiber, alumina fiber, alumina borosilicate fiber, a dispersant, and water to produce a slurry of fibrous ceramic material. The slurry is then placed within a mold and vaccuum pressure is applied thereto to substantially remove the water to form a fibrous ceramic body. The fibrous ceramic body is then dried and sintered to a temperature sufficient to bond the ceramic material together to form a porous ceramic article. Simultaneously, the fibrous ceramic body is heated to a temperature sufficient to generally burn off the organic particulate to create voids interconnecting the pores to form a permeable fiber reinforced porous ceramic article.
Claims9
A method of manufacturing a permeable fiber-reinforced ceramic insulation article comprising:
- (a) providing a mixture having silica fiber, alumina fiber, an alumina borosilicate fiber, water, and dispersant;
- (b) disposing a organic particulate within said mixture;
- (c) mixing said organic particulate within said mixture to produce a (slurry of fibrous ceramic material;
- (d) placing said slurry within a mold and applying pressure to said slurry to substantially remove said water;
- (e) maintaining said pressure on said slurry in said mold to form a fibrous ceramic body;
- (f) drying said fibrous ceramic body;
- (g) sintering said dried fibrous ceramic body to a temperature sufficient to bond said fibers of said ceramic material together and form a porous ceramic article and that is further sufficient to generally burn off said organic particulate to create voids interconnecting said pores to form a permeable fiber reinforced porous ceramic insulation article.
A method of producing a permeable fiber-reinforced ceramic article comprising:
