    摘要: Provided is a method for producing an inorganic fiber-bonded ceramic material, which can produce, at a high yield, an inorganic fiber-bonded ceramic material with fewer defects, and with an end part and a central part equivalent to each other in microstructure and mechanical properties, and also makes it possible to increase the ceramic material in size. The method for producing an inorganic fiber-bonded ceramic material is characterized in that it includes: a first pressing step of setting, in a carbon die, a laminate to be surrounded by a ceramic powder, the laminate obtained by stacking a coated inorganic fiber shaped product including an inorganic fiber part of inorganic fibers that have a pyrolysis initiation temperature of 1900°C or lower, and a surface layer of an inorganic substance for bonding the inorganic fibers to each other, and pressing the laminate at a temperature of 1000 to 1800°C and a pressure of 5 to 50 MPa in an inert gas atmosphere; and a second pressing step of pressing a ceramic coated laminate obtained in the first pressing step at a temperature of 1600 to 1900°C, which is higher than that in the first pressing step, and at a pressure of 5 to 100 MPa in an inert gas atmosphere.
