はガラス粉 55％ 45％ 30％ ここで1200℃までの焼成温度でタルク及び長石を主原
料に使った理由は焼成収縮が少ないために焼成後の変形
が小さいことと比較的低温で焼成しても強度が出るため
である。Here, the clay for ceramics consists of the following components: [Components and firing temperature of the clay for ceramics] 1100 ℃ 1150 ℃ 1200 ℃ 1250 to 1300 ℃ Talc 25% 30% 40% Porcelain stone 30 to 60% Feldspar 15 % 20% 25% Feldspar 20-40% Bentonite Kaolin or clay 5% 5% 5% 10-30% Glaze or glass powder 55% 45% 30% Talc and feldspar are the main raw materials at the firing temperature up to 1200 ℃. The reason for using it is that the shrinkage after firing is small, so that the deformation after firing is small and the strength can be obtained even if fired at a relatively low temperature.
次に陶石、長石及びカオリン等で調合された坏土を使
うと焼成温度を高くすることが出来る。Next, by using a kneaded clay mixed with porcelain stone, feldspar, kaolin, etc., the firing temperature can be raised.
スポンジ（１）に泥漿を付着させるためには泥漿の濃
度は固形分１に対して水0.6の割合が適当である。In order to attach the sludge to the sponge (1), the concentration of the sludge should be 0.6 of water to 1 of solid content.
塗布量は例えば1cm×1cm×0.5cmのスポンジに対して
0.15g程度が望ましい。The coating amount is 1 cm x 1 cm x 0.5 cm for a sponge, for example.
About 0.15g is desirable.
一方作りたい多孔セラミック板（２）の目のあらさに
合わせてスポンジ材（１）の目のあらさを適当に選べば
任意に目のあらさを変えることができる。On the other hand, the roughness of the eyes can be arbitrarily changed by appropriately selecting the roughness of the sponge material (1) according to the roughness of the porous ceramic plate (2) to be produced.
多孔セラミック板（２）の大きさ及び厚さを調整する
ため本発明においては泥漿を塗布したスポンジを乾燥前
に複数枚接続して焼成するものとしそれにより相互に付
着一体化し大きさ及び厚さの必要な多孔セラミック板
（２）を作ることができる。In order to adjust the size and thickness of the porous ceramic plate (2), in the present invention, a plurality of sponges coated with slurry are connected and fired before drying, whereby they are adhered and integrated with each other to form a size and thickness. The required porous ceramic plate (2) can be produced.
以上の通りスポンジ材（１）に陶磁器用坏土の泥漿を
スプレーし複数枚接続して乾燥させそれを焼成する。As described above, the sponge material (1) is sprayed with slurry of clay for ceramics, a plurality of the sponge materials are connected, dried, and fired.
焼成温度は前述の通りであり時間は例えば24時間焼成
して第２図に示す様な多孔セラミック板（２）が製造さ
れるのである。The firing temperature is as described above and the firing time is, for example, 24 hours to produce the porous ceramic plate (2) as shown in FIG.
すなわちスポンジ材（１）は焼成時に焼失しセラミッ
クのみの多数の通気孔（陶磁器用坏土が内部まで十分い
き渡り厚さが厚くなっても均一な多数の通気孔）を有す
る多孔セラミック板（２）になるのである。That is, the sponge material (1) is burnt out during firing, and has a large number of ventilation holes made of only ceramic (a large number of ventilation holes that are uniform even if the clay for ceramics is sufficiently extended to the inside) (2) ).
