に使用されることを知見したものである。Ceramic porous bodies with a three-dimensional network cell structure with internal communication spaces have a wide range of uses, including the P phase of molten metal, catalyst carriers, diesel particulate filters, and even breathable insulation materials, making them industrially useful. It is something. However, when used in these applications, they are often used in environments with temperatures ranging from several hundred degrees to tens of hundreds of degrees, so a ceramic porous body with high strength at high temperatures is required.
Recently, there has been a demand for improved creep resistance at high temperatures in order to expand the range of application of ceramic porous bodies. 1 In view of the above circumstances, the present inventors have conducted intensive studies on ceramic porous bodies that have excellent creep resistance at high temperatures, and have developed a framework for ceramic porous bodies that has a three-dimensional network cell structure with internal communication spaces. When formed from silicon oxide produced by firing a part or all of the lattice structure, it has excellent high-temperature creep properties and high strength at high temperatures, which makes this ceramic porous body It has been found that this material is suitable for use in applications exposed to high temperatures, such as breathable heat insulating materials.

る方法が採用できる。When obtaining the entire ceramic porous body as described above, it is possible to use a product manufactured by attaching a ceramic slurry to a flexible polyurethane foam without a cell membrane and removing carbonization from the flexible polyurethane foam by baking this. (By forming the entire ceramic porous body from a flexible polyurethane foam without a cell membrane in this way, a cage-shaped ceramic porous body consisting of the edges of a regular dodecahedron is obtained, which has a low porosity. is large, so the exhaust gas passes through with little pressure loss, and the internal communication space is intricate, so for example, if the acid 2 solution used for this ceramic porous sound-breathable insulation material is used, the exhaust gas can pass through this internal communication space. (This ensures reliable contact with the lattice as it passes through the space, allowing efficient heat exchange.) However, when producing a ceramic multilayer body using this method, for example, a ceramic slurry mainly composed of alumina or cordierite is used. After the entire ceramic porous body is formed by heating and firing, a ceramic slurry containing silicon carbide as a main component is coated and adhered to the skeletal lattice of this ceramic porous body, and this is fired to form silicon carbide and total silicon oxide. By making the following changes, it is possible to adopt a method in which the skeletal lattice surface of the ceramic porous body is made of silicon oxide produced from silicon carbide.

を酸化する方法を採用してもよい。However, more appropriately, the entire skeleton lattice of the ceramic porous body is made of silicon oxide produced from silicon carbide. In this case, a ceramic slurry containing silicon carbide as a main component is attached to a flexible polyurethane foam without a cell membrane, dried, and fired. Violet oxidation and sintering may proceed simultaneously; a method is adopted in which first calcining is performed in a neutral or reducing atmosphere to sinter the silicon carbide, and then heating is performed in an oxidizing atmosphere to oxidize the carbonization.

It is extremely effective because it increases the stability of the slurry and the dry strength when the slurry is attached, and promotes fertilization, strength, and sintering. In this case, the amount of clay and waxite mixed is not necessarily limited, but it is preferable that the content of silicon carbide is 80% by weight or more, clay is 10% by weight or less, and waxite is 10% by weight or less based on the total amount of solids. . Furthermore, silicon carbide preferably has an average particle diameter of 10 to 100 μm.
