その目的は低火度で焼成でき、かつそりのない薄型大型

を提案するにある。The purpose is to propose a new ceramic base composition that can be fired at low heat and can be made into thin, large tiles without warping.
従来、磁器の多くは、粘土に陶石、長石、１ト石などを

。Conventionally, most porcelain is made by adding moisture to a base composition of clay mixed with pottery stone, feldspar, orite stone, kneading it, drying it, and firing it at a temperature exceeding 1250°C. There is.

りが発生し、良好な製品を得ることは困難であった。In recent years, in order to fire porcelain at a low temperature of 1200 degrees or less, there have been descriptions of porcelain base compositions that use rhyolite (approximately 70%) in combination with clay (e.g., JP-A-51-81809). , a description of a base composition for porcelain whose fire temperature is further lowered by adding anti-firestone (50 to 70%) and glass cullet (5 to 30%) to clay (e.g., JP-A-54-7760).
7), but in order to make large (e.g. 7150 m x 450 rnx) and thin (e.g. 5 mm) plate-shaped objects using these substrates, molded products such as
When fired with Roller-1 of a roller house kiln, warping occurred and it was difficult to obtain a good product.
一方、特殊外素地（例えば特公昭５２ ９６８７−号の

型の磁器タイルとすることは困難であった。On the other hand, there have been attempts to manufacture thin, large-sized tiles using non-special materials (for example, 60-80% volcanic ash and 40-20% low-grade clay from Special Publication No. 52-9687); It has been difficult to produce large, thin porcelain tiles without warping at temperatures below 0°C.
本発明者は、新規な磁器用素地組成物を見出し、低火度
（１２００°０以下）で焼成でき、かつそり ゛の少な
い薄型大型のタイルとするととも可能とずべく鋭意研究
した結果、本発明をみ出した。The present inventor discovered a new porcelain base composition, and as a result of intensive research to create a thin, large tile that can be fired at low heat (below 1200°0) and has less warpage, the present inventor has developed the present invention. I discovered an invention.

Preferably, it is a composition containing 1 to 10% as a main component.

It is 0%. If it is less than 4%, it becomes difficult to shape the base material, and if it exceeds 40%, it becomes difficult to perform low-temperature firing. For example, if a lower fire temperature is desired so that a metsch kiln can be used, the amount may be 4 to 10%.

ある。As the natural glass used in the present invention, any glass that has been conventionally used to lower the firing temperature of porcelain can be used, such as anti-firestone, obsidian, perlite, and shirasu. The resulting porcelain is far more resistant to fire in terms of its stable quality and low fire resistance. These natural glasses
Generally particle size is 150 mesh or less, particularly particle size is 2.
It is preferable that the particle size be 0.00 mesh or less, and by reducing the particle size, it can be mixed uniformly into the composition and the fire temperature can be lowered. The amount of natural glass used in the present invention is from 50 to 96% of the 100% by weight solid content of the base composition. If it is less than 50%, it will be difficult to make it into porcelain at low heat, or it will be difficult to make it into porcelain with a low fire temperature, or it will be difficult to make it into porcelain at low heat.
If you use 'ri', warping may occur. On the other hand, if natural glass with a content exceeding 96% is used, warpage during firing will be extremely high. When choosing a particularly low fire rate in terms of energy d
: The amount of natural glass used is preferably 70 to 96%.

If it is less than 1%, the addition effect will not be produced.On the other hand, if it is added in a large amount exceeding 10%, surprisingly, the non-uniformity of the structure in the fired porcelain molded product is more noticeable than the effect of lowering the firing temperature. This will result in an uneven product.

It is acceptable to add 1 to 0.5% (usually about O]%).
