である。As a result of various studies, the present inventor has used crystallized glass as glass dough,
Further, the present inventors have found that the above object can be achieved by replacing a part of the clay mineral used as the aggregate with ceramic powder such as alumina, and propose the present invention.

【作用】本発明者は、焼結ガラス物品において白華物の
発生メカニズムを詳細に調査した結果、次のような事実
が明らかになった。The present inventor has conducted a detailed investigation on the mechanism of the generation of white matter in a sintered glass article, and as a result, the following facts have become clear.
【０００９】つまり粘土鉱物には吸水性があるため、水

の結晶（Ｎａ2 ＳＯ4 ）が析出する。この結晶が白華物
である。That is, since clay minerals have water absorption, water is easily taken into glass articles. In particular, when the content of the clay mineral is large, moisture is sucked up from the back surface to the front surface through the clay mineral. Incidentally, clay minerals contain a large amount of sulfur components as impurities, which are eluted as sulfate ions in water. Also, at the interface between the clay mineral and the glass fabric,
The sodium component in the glass elutes into the water that has been sucked up. Water containing sulfate ions and sodium ions is sucked up to the surface of the article and concentrated, and the water is evaporated to precipitate white crystals (Na 2 SO 4 ). These crystals are white flowers.
【００１０】従って、白華物の発生を防止するために

で置き換えることを特徴とする。Therefore, in order to prevent the occurrence of white matter, it is important that sodium ions are not eluted from the glass constituting the fabric as much as possible and that the water absorption of the glass article is reduced. Therefore, in the present invention, a crystallized glass having high chemical durability is used for the dough to prevent the elution of sodium ions, and in order to reduce the water absorption, a part of the clay mineral is replaced with a ceramic powder having no water absorption. It is characterized by replacing with.

５０50% by weight, preferably 5 to 40% by weight of crystallized glass, or crystalline glass having the property of firing to give a crystallized glass of 5 to 50% by weight, preferably 5 to 40% by weight It is desirable to do. The reason for limiting the amount of precipitated crystals in this way is that if the amount of precipitated crystals is less than 5% by weight, the glass is too viscous, so the softening temperature is lowered, the reaction with the aggregate becomes strong, and the material is easily deformed by firing. In addition, gas generated at the time of firing is difficult to escape, and large pores remain in the fired body, so that mechanical strength tends to decrease. On the other hand, when the amount of crystals exceeds 50% by weight, the glass powder is hardly softened and hardly formed into a dense fired body, so that the water absorption increases and the mechanical strength tends to decrease. As such a crystallized glass powder or a crystalline glass powder, for example, β-wollastonite, diopsite, forsterite, garnite, anorthite, and debitrite can be used as a main crystal. it can.

The mixing ratio of glass powder, clay mineral and ceramic powder is expressed in weight percentage,
Glass powder 40-90% (preferably 50-80%),
5-40% (preferably 5-30%) of clay mineral powder and 5-40% (preferably 5-30%) of ceramic powder are suitable. If the glass powder content is less than 40%, it is difficult to obtain a dense sintered body, resulting in a decrease in mechanical strength and an increase in water absorption. If the amount of the clay mineral powder is less than 5%, molding becomes difficult, and if it is more than 40%, the water absorption of the glass article increases remarkably, so that white matter is easily generated, and a dense sintered body is hardly obtained. Become. If the amount of the ceramic powder is less than 5%, molding becomes difficult, and at the same time, it tends to flow and deform during firing, and if it is more than 40%, it becomes difficult to obtain a dense sintered body. In kneading these powders, the water content is adjusted in order to improve the moldability.
About 0% by weight is preferable. At the time of mixing or kneading the powder, an amorphous glass powder or an inorganic pigment powder may be added. In this case, the proportion of the amorphous glass powder in the whole powder is suitably 40% by weight or less, and the amount of the inorganic pigment powder is preferably in the range of 0.1 to 25% by weight based on the whole glass powder. is there.

過ぎて成型体が変形してしまう可能性がある。Thereafter, the molded body is fired. When the molded body is heated, first, water and the like in the molded body are sublimated, and water of crystallization of the clay mineral is released. When the temperature further rises, the crystallized glass powder or the crystalline glass powder is softened and integrated with the clay mineral or the ceramic powder, and crystals are precipitated from the crystalline glass. In this way, a sintered crystallized glass article in which the clay mineral and the ceramic powder are dispersed and present in the crystallized glass dough is obtained. The firing is 1000-1
It is preferable to carry out in a temperature range of 100 ° C. The reason is,
In this temperature range, the glass powder is densely fused and integrated with the clay mineral, but is not softened enough to deform the molded body itself. Therefore, if the firing temperature is lower than this temperature range, the glass powder does not soften sufficiently and the molded body is difficult to be densified. On the other hand, if the firing temperature is too high, the glass powder becomes too soft and the molded body may be deformed. There is.

る。As described above, the sintered and crystallized glass article of the present invention has a very low water absorption and is unlikely to produce white matter. In addition, since it has a quaint appearance in which ceramic-like clay minerals and ceramics are mixed in a crystallized glass fabric with high mechanical strength and gloss, it can be used for decorative materials such as exterior walls, interior walls and floors of buildings. It is suitable as a material.
