摘要： PROBLEM TO BE SOLVED: To provide a silicon carbide sintered body which can be obtained safety in terms of environmental hygiene and has an excellent sintering property; and a method of producing the same.SOLUTION: The production method comprises steps of: preparing a slurry by adding carboxymethylcellulose to silicon carbide ceramic as a carbon source; forming a compact using the slurry; and calcinating the compact in a non-oxidative atmosphere. Carboxymethylcellulose used as a carbon source is, unlike carbon black, soluble in water, has thickening, swelling, and dispersing effects for aqueous solutions, and can suppress flotation and sedimentation of each powder and homogenize the same. By substituting all or a portion of the carbon source with carbon derived from carboxymethylcellulose, addition of carbon black can be stopped or reduced. As a result, the carbon source is dispersed uniformly, and suppression of aggregation becomes possible and, further, pores which are formed in the sintered body due to aggregation decreases.

摘要： PROBLEM TO BE SOLVED: To provide low-thermal-expansion ceramics, a stage for an exposure apparatus, and a method of manufacturing low-thermal-expansion ceramics by which changes of flatness over time can be prevented, and chemical resistance can be improved.SOLUTION: There is provided low-thermal-expansion ceramics in which a positive thermal expansion material which expands to temperature rise is combined with a negative thermal expansion material which shrinks to temperature rise. The negative thermal expansion material consists of zirconium phosphate tungstate or zirconium tungstate, and the positive thermal expansion material consists of non-oxide. Since micro cracks are not taken in consideration because of using no eucryptite as the negative thermal expansion material, changes of flatness over time caused by micro crack can be prevented. Further, chemical resistance can be increased.
