（celsian）〔（BaO・CaO・K2O・NaO）Al2O3・
2SiO2〕が生成するからである。 As is clear from the above measurement results, when barium carbonate is blended into raw materials with a high alkali component content, tiles with a low hydration expansion rate can be obtained. This is the alkaline components K 2 O and Na 2 O and alkaline earths contained in the raw materials.
CaO and BaCO 3 blended with SiO 2 and Al 2 O 3 produce crystalline heavy feldspar (celsian) [(BaO・CaO・K 2 O・NaO)Al 2 O 3・
2SiO 2 ] is generated.

It is impossible to generate heavy feldspar by incorporating almost all of the alkaline components contained in the weight percent or more. Furthermore, if the content exceeds 30% by weight, the blended material loses its plasticity, making it impossible to form tile bases.
