Abstract

PROBLEM TO BE SOLVED: To obtain a sintered glass material without generation of an efflorescent material even in a case of using soda-lime glass by making a structure in which clay mineral and ceramic as aggregates are dispersed in a ground composed of amorphous glass. SOLUTION: This sintered glass material comprises a ground of amorphous glass in which clay mineral and ceramic as aggregates are dispersed. Preferably, the sintered glass material is composed of 40-90wt.% of amorphous glass component, 5-30wt.% of clay mineral component and 5-40wt.% of ceramic component. The sintered glass material is produced by adjusting moisture (added moisture amount is preferably about 2-10wt.%) of a mixture of amorphous glass powder, clay mineral powder and ceramic powder, blending, molding and baking. Preferably, the baking temperature is within a range of 1,000-1,100 deg.C.

2. Description of the Related Art Amorphous glass powder such as soda-lime glass and clay mineral powder such as kaolin and bentonite are kneaded.
A sintered glass article obtained by molding and firing is a material having a high mechanical strength and exhibiting a novel appearance in which a glossy glass fabric and a ceramic-like clay mineral portion are mixed. Moreover, resources can be effectively used because waste glass can be used as the amorphous glass powder. In addition, since the raw material cost is low, and there is no deformation after firing, post-processing is not required, and it can be manufactured at low cost.

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.

Therefore, it is necessary to reduce the water absorption of the glass article in order to prevent the occurrence of white matter. For that purpose, the content of the clay mineral may be reduced, and it may be fired at a temperature as high as possible to densify. Therefore, the sintered glass article of the present invention reduces the water absorption of the glass article by replacing a part of the clay mineral with a ceramic powder having no water absorption and having a lower reactivity with glass than the clay mineral. Suppresses the elution of sulfate ions and alkali ions that cause flower.

Further, a ceramic powder is prepared. The average particle size of the ceramic powder is preferably 40 μm or less. As the ceramic powder, one having no water absorption and having a lower reactivity with glass than a clay mineral, for example, one or more selected from alumina, mullite, cordierite, zirconia, zircon and the like can be used. In particular, alumina, mullite and zirconia are preferable because of their extremely low reactivity with glass. The reason why a material having low reactivity with glass is preferred is as follows. That is, the smaller the reactivity with the glass, the higher the effect of suppressing the fluidity of the glass during firing and maintaining the shape. On the other hand, since the clay mineral has high reactivity, it can be fired at a higher temperature and a dense sintered body can be obtained by using ceramic powder having lower reactivity as an aggregate together.

Next, the amorphous glass powder, the clay mineral, and the ceramic powder are mixed at a predetermined ratio, and the mixture is kneaded by adjusting the water content. The mixing ratio of the glass powder, the clay mineral and the ceramic powder is, in terms of weight percentage, 40 to 90% of the amorphous glass powder.
% (Preferably 50-80%), clay mineral powder 5-30
% (Preferably 5 to 25%), ceramic powder 5 to 40
% (Preferably 5 to 30%) is appropriate. If the amount of the amorphous glass powder 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. If the amount is more than 30%, the water absorption of the glass article increases remarkably, so that white matter becomes very likely to occur, and it becomes difficult to obtain a dense sintered body. . 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 addition, when kneading these powders, moisture is adjusted to improve moldability,
The amount of water added at this time is preferably about 2 to 10% by weight. When mixing or kneading the powder, a crystallized glass powder, a crystalline glass powder, or an inorganic pigment powder may be added. In this case, the ratio of the crystallized glass powder or the crystalline glass powder to the whole powder is suitably 40% by weight or less, and the addition amount of the inorganic pigment powder is 0.1 to 25% by weight based on the whole glass powder. Is suitable.

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 glass powder softens and integrates with the clay mineral or ceramic powder to obtain a sintered glass article in which the clay mineral or ceramic is dispersed and present in the amorphous glass material.
The firing is preferably performed in a temperature range of 1000 to 1100 ° C. The reason is that, in this temperature range, the glass powder softens and fuses and integrates with the clay mineral or ceramic powder, but does not soften enough to deform the molded body itself. Therefore, if the firing temperature is lower than this temperature range, the molded body is difficult to be densified because the glass powder is not sufficiently softened, while if the firing temperature is too high, the glass powder may be excessively softened and the molded body may be deformed. Is high.
