になっている。Furthermore, since it is not possible to obtain a homogeneous porosity with the conventional method, several layers (fFl) of ceramics with several types of particle size distributions are used.
For example, fine-grained ceramics are placed on the outside of the tube and coarse-grained ceramics are placed on the inside, then fired.

5■, length 1 tn is used. Attach this to a die that can be rotated around its axis, and while rotating it, wrap a polyacetal paper tape (width 25Wa1, thickness 13m) diagonally that has been impregnated with alumina water slurry, leaving about 25m at each end, leaving t2m + thickness. I'll go overboard. Furthermore, a paper tape 3 of the same quality is further wrapped around it. Grasp one end and hang it vertically to air dry for 12 hours. Hold the ceramic part horizontally and place it in an electric furnace. To completely remove moisture, hold it at 120°C for 1 hour in a nitrogen stream, and then hold it at 50°C for 1 hour. The temperature was raised at 350 to 400°C for another 1 hour, then changed to an air atmosphere, and the temperature was raised at 50°C for 1 hour to 1300°C.
Raise the temperature to 700℃, hold it for 2 hours, and then heat it to 50-100℃ for 1 hour.
Cool slowly at ℃.

率は約３０〜４０％のものが得られた。A fired tube with a length of 1.9 m and a diameter of J 75 cppt had a porosity of about 30 to 40%.
上記した実施列のほか、セラミックスを含浸しない紙テ
ープは省略することができるがこの場合には風乾時間を
若干増加させる必要がある。In addition to the embodiments described above, the paper tape not impregnated with ceramics can be omitted, but in this case it is necessary to increase the air drying time slightly.
また紙管１の代りに紙質棒を用いて強度を強めて含水効
果を上げることも可能である。It is also possible to use a paper rod instead of the paper tube 1 to increase the strength and improve the water absorption effect.

に至る経過は大差はない。As the ceramic, in addition to the above-mentioned examples, partially stabilized ceramics such as zirconia-yttolya type zirconia-calcia type, and hechilya-calcia type can be used. Although the maximum temperature for firing varies depending on the type, the process of supporting until air drying, paper tubes or paper rods with a dehydrating effect, and the process leading to carbonization and self-combustion of the paper tape is not much different.
紙テープが好ましいと思われるが、綿布などセルローズ
系、或はポリアセタール等炭化の容易なものは使用され
るが連通気孔をもつには不織布、紙が最適である。Although paper tape is considered preferable, cellulose-based materials such as cotton cloth, or materials that are easily carbonized such as polyacetal may be used, but non-woven fabrics and paper are most suitable as they have continuous pores.
