縮、変形を防止している。2. Description of the Related Art Conventionally, this type of ceramic block has been manufactured by molding and firing ceramic clay into a predetermined shape. However, since the shrinkage and deformation during firing are large, it is difficult to obtain an accurate shape and dimensions. Therefore, shreds obtained by firing and crushing a fire clay or a mixture of fire clay and alumina or silica, which are mainly made of fire clay, are mixed with the clay to prevent shrinkage and deformation during firing.

る。The crushed shells used in the present invention are:
It is obtained by grinding oysters, clam shells, clam shells, Akoya shells and the like, and it is desirable that the crushed material has a size of 2 mm or less. The above-mentioned shells are generated in large quantities from shellfish processing plants, shellfish cooking sites, etc., but there has been little effective use in the past, and slightly ground oysters are used for purification of fish breeding water and the like. And many have been disposed of.

It is desirable that the blending amount of the ground shell is in the range of 10 to 40% by weight in the blend.
【０００８】上記配合物の成形物は次いで焼成される。

る。In the ceramic block of the present invention thus obtained, the internal structure becomes porous, and the internal stress of the molded product generated during firing is absorbed by such a porous structure. The shrinkage and deformation of the ceramic block due to the internal stress, that is, the firing strain is suppressed, and the crack is prevented. Further, such a ceramic block having a porous structure is light in weight and easy to handle. In addition, by blending the crushed shell, the ceramic block becomes pale and has a preferable appearance.

ロック等に有用である。According to the present invention, crushed shells are added to porcelain clay instead of chamotte, so that the cost of materials is very low, the occurrence of firing distortion is effectively suppressed, and cracks are reliably prevented. Further, the ceramic block has a porous structure, so that the weight is reduced. Therefore, in the present invention, a large amount of pulverized shells can be effectively used, and the amount of pottery clay used can be saved. The ceramic block of the present invention is pale in color and has an excellent appearance, and is useful for a building block such as an outer wall material, a permeable pavement block and the like.
