結晶性アルミノケイ酸塩の物理化学的研究(第5報) : ゼオライト生成における結晶のノゼライトへの転化

It has been confirmed that Noselite may be prepared when both alkali and sodium sulfate are reacted with Na₂O·Al₂O₃·2SiO₂ even at 80°C under normal pressure. The rate of crystallization was found to depend on the concentration of the mixture of starting materials and especially the influence by alkali was observed to be much greater than that by sodium sulfate. In the crystallization of Noselite, formation of Zeolite A is taken place initially as an intermediate, and it is then transformed to Noselite. However, Noselite was found to be much more difficult to be transformed from Zeolite A as a starting material, rather than from gel.
