It is characterized in that the glass is foamed and fired. The type of the clay for ceramics used in the present invention is not particularly limited, and the firing temperature may be selected in accordance with the fire resistance of the clay for ceramics in use.
When white clay is used as the clay for ceramics, there is an advantage that coloring can be easily performed using metal oxide.

ができるようにするためである。As the glass powder to be added to the clay for ceramics, a waste glass bottle or glass waste generated during glass processing or the like is finely ground and used. The particle size of the glass powder used is important for suppressing deformation and sintering the glass into a predetermined shape when the glass is foamed and fired. If the particle diameter of the glass powder is too large, the glass powder is deformed when foamed, resulting in a defective shape, and the surface of the fired body becomes rough, resulting in poor appearance of the finish. In the present invention, those having a particle diameter of about 200 μm or less, and those having a particle diameter of about 20 to 50 μm in normal use can be suitably used. The reason why fine particles are used as the glass powder is to improve the moldability, and to use the glass fine particles so that they can be uniformly mixed with the clay for ceramics to form a uniform foam.

When the ratio by weight of the glass powder is 3% or less, the foaming action at the time of firing is weak, and the change to the substrate becomes small. In addition, the ratio by volume of glass powder is 5
In the case of about 0% or more, the glass melts each other,
No foaming. The amount of glass powder to be added depends on the quality of the clay for ceramics, but is usually 10% to 30% by weight.

ク粉末を加えればよい。The addition of the talc powder to the raw material for molding has a meaning as an auxiliary for foaming the glass powder. This is because if a raw material for molding is produced only with the clay for ceramics and the glass powder, the glass melts with the clay and becomes a sintered sintered body having a high specific gravity. By adding the talc powder, the glass powder reacts with the talc powder during firing, so that the glass powder can be suitably foamed. The amount of the talc powder added may be in accordance with the amount of the glass powder added. Usually, the talc powder may be added in an amount of about 20 to 30% by weight with respect to the added amount of the glass powder 100.

Water may be added to glass powder and talc powder, mixed, and kneaded with a water mixing kneader. The moisture content is about 18% by weight. The kneading of the raw materials for molding may be carried out using a usual soil-making line for kneading tiled clay or wet compacted soil.

The forming of the forming raw material is not limited to the extrusion method, and a method such as press forming can be used. The firing temperature is adjusted according to the ratio of the amount of the glass powder mixed with the raw material for molding.
When the glass powder is about 10% by weight, the firing temperature is 1
About 250 ° C, about 1200% for about 15%, 2
In the case of about 0%, the temperature is about 1150 ° C. The firing furnace can be in either an oxidizing atmosphere or a reducing atmosphere.

It is fired at 1200 ° C., and has a specific gravity of about one half (specific gravity 1.2) of that fired without adding conventional glass powder. In the case of this fired body, the volume due to glass foaming occupies about 50% of the entire volume.

When the sintering temperature is set to a high temperature, the foaming proceeds and the specific gravity becomes small, and the effect of weight reduction is remarkable. Therefore, it is necessary to set a firing temperature at which required foaming is obtained and a predetermined formability of the fired body is obtained.

This manufacturing method is different from a method in which a space is previously formed in a molded body to reduce the weight when molding raw materials are formed, and a fired body is formed by foaming glass powder contained in the molded body at the time of firing. A space portion is formed therein to reduce the weight.

Can be. In addition, since the characteristics of the material are stable, there is an advantage that stable production can be achieved by accurately controlling the mixing amount of the glass powder and talc powder and the firing temperature. In addition, when foaming is performed using glass fine powder, the bubbles become independent bubbles, the water absorption of the fired product can be reduced, and it can be suitably used as an exterior material for buildings. In addition, by properly managing the firing conditions, the product can be provided as a product satisfying standard requirements such as bending strength, frost resistance, and chemical resistance required for the exterior material. Another advantage is that glass powder can be obtained abundantly as waste glass or the like.

Therefore, in comparison with this conventional example, the fired product of this example is 1.37 times the volume of the conventional product in volume, and the specific gravity is reduced by that much.

It is fired at 00 to 1300 ° C. At that time, the color of the tile is due to sintering of the metal oxide (iron, manganese, titanium, chromium, nickel, etc.) and the material. In the case of the present embodiment, since it is fired at about 1200 ° C., the same color development as that of the conventional exterior tile is possible and it can be provided in a variety of colors. This is because if the firing temperature is low, the color developability deteriorates.

A space is formed in the body, whereby the weight can be effectively reduced. Further, by uniformly mixing and foaming the glass powder, the cells of the fired body become closed cells, the water absorption of the fired body can be reduced, and the fired body can be suitably used as an outer wall material or the like. Further, it can be obtained as a fired body having required strength and durability, and has a remarkable effect that it can be suitably used as a fired body for construction such as tiles and tiles.
