Abstract
Chemical treatments involving ion exchange cause gross onedimensional swelling in water of single crystals of vermiculite minerals. A delicate balance of forces holds the individual silicate layers (10 angstroms thick) parallel to one another although separated by several hundred angstroms. Colloidal dispersions produced from the swollen crystals are morphologically unique and show strong filmforming characteristics.
摘要
化学处理涉及离子交换会导致蛭石单晶体在水中发生明显的一维膨胀。尽管相隔数百埃，但各种力的微妙平衡使各个硅酸盐层（厚 10 埃）保持彼此平行。从膨胀晶体中产生的胶体分散体在形态上是独特的，并显示出强烈的成膜特性。
