    摘要: A herapathite has a capillary crystal form in which its iodine atoms are oriented in a major axis direction of the capillary crystal form. The herapathite obtained is expressed by a chemical formula, xC.sub.20 H.sub.24 N.sub.2 O.sub.2.yH.sub.2 SO.sub.4.zHI.sub.3, in which a ratio of a number of the sulfuric acid molecules (y) with respect to a number of the iodine atoms (3z), i.e., (y/3z), is less than 0.5. The production process includes a reaction step, a first separating step, a recrystallizing step and a second separating step. A solvent used in the recrystallizing step is at least one of water and alcohol. A mixing weight ratio of water with respect to alcohol of the solvent is more than 50/50 or less than 10/90. The herapathite does not degrade even after it is heated up to 130.degree. C., and it is applicable to an automobile light shielding glass which should show a high transparency when a voltage is applied thereto.

    摘要: The present invention provides an inorganic-organic hybrid material having both the characteristics of the inorganic material and the characteristics of the organic material. The material has a lamellar structure formed by piling a sheet of silicon tetrahedrons upon a sheet of titanium octahedrons. In this lamellar structure, an organic group is bonded to a center atom of a tetrahedron via a covalent bond. The organic group can be polymerized to make the organic phyllotitanosilicate a tough and hard coating material. The hybrid material of the present invention thus has both the characteristics, such as high hardness and heat resistance, of the constitutive inorganic material and the characteristics, such as flexibility and filmability at room temperature, of the constitutive organic material, and further has an excellent UV-blocking property.
