摘要： PURPOSE:To promote heat transfer of a refractory material and air and prevent deposition of floating material to wall surface of gas flow path by piling the refractory material for heat storage chamber up around the gas flow path in a specific manner and providing a projection part having longer height in ring shape. CONSTITUTION:The aimed refractory material 10 is nearly octagonal in outline in the upper face 8 and lower face 9 and cylindrical as the whole and has two openings at upper and lower faces. A space connecting two openings forms a gas flow path 2. A dry masonry structure opened in vertical direction and having long and narrow, many and mutually parallel gas flow paths 2 and 3 can be formed by vertically and laterally pilling up the refractory material 10. A longer projection part 4 is arranged in a ring shape at intervals of L around the gas flow paths 2 and 3. Outside flow path wall and inside flow path wall are each adjacent to the upper face 8 and lower face 9. Thereupon, in relations among height H having longer projection part 4, height h having shorter projection part 6 and length L of the refractory material, h/H is

摘要： PURPOSE:To obtain silicon carbide whisker in high yield by generating cluster of silicon carbide whisker having high purity and suitable for reinforcing use in a hollow part of a molded body inexpensively by mixing silica, carbon, alumina, fluoride flux, and a caking material in a specified proportion, molding the mixture to obtain a molded body, and heat-treating the molded body by shielding from outside atmosphere. CONSTITUTION:10-60wt.% silica, 10-60wt.% carbon (e.g., coke powder), and 10-60wt.% alumina are mixed so as to attain 100% in total. Then, adding 1-5wt.% fluoride flux (e.g., NaF), and 2-10wt.% caking material (e.g., phenolic caking material) to the above-described mixture, and a hollow molded body 1 is obtd. after kneading the mixture. The molded body 1 is charged to a graphite vessel 3, sealed with a graphite disc 4, wrapped with a ceramic fiber blanket 5, and heated at >=1,350 deg.C noncatalytically with a high frequency induction furnace 6 while shielding from outside atmosphere. Thus, clusters 2 of silicon carbide whisker are generated in the hollow parts of the molded body 1.
