前記の陶板の表面にこの釉薬を塗布して、釉薬層を設け
た。This glaze was applied to the surface of the ceramic plate to provide a glaze layer.
第３図に示した装置の函体２３の中に、発泡性組成物、
その上に溶融層原料を入れ、その上に釉薬層を設けた陶
板を載せた。In the box 23 of the device shown in FIG.
A molten layer raw material was placed on top of it, and a ceramic plate with a glaze layer was placed on top of it.
この函体２３を台車２１に載せ、予熱炉２９、加熱炉３
０、徐冷炉３１と順次通過させた。This box 23 is placed on the trolley 21, and the preheating furnace 29 and the heating furnace 3
0 and an annealing furnace 31.
加熱炉３０を通過するときに、発泡性組成物及び陶板は
１２００°Ｃに加熱される。すると、発泡性組成物は溶
融し、発泡してセラミック発泡体となる。また、同時に
陶板の表面の釉薬層は溶融して、陶板表面に接着して溶
融層を形成する。溶融層は溶融し、陶板とセラミック発
泡体とを強固に接着する。When passing through the heating furnace 30, the foamable composition and ceramic plate are heated to 1200°C. The foamable composition then melts and expands into a ceramic foam. At the same time, the glaze layer on the surface of the ceramic plate melts and adheres to the surface of the ceramic plate to form a molten layer. The molten layer melts and firmly bonds the ceramic plate and ceramic foam.
徐冷炉３１を通過して、約１００°Ｃまで冷却されて、
炉からでてくる。It passes through a slow cooling furnace 31 and is cooled to about 100°C.
It comes out of the furnace.
このようにして製造したセラミック発泡体は表面に陶板

白色の釉薬層があり、建築材料として掻めて有用なもの
である。The ceramic foam thus produced has a ceramic plate firmly adhered to its surface, and the surface of the ceramic plate has a beautiful milky white glaze layer, making it useful as a building material.
