摘要：

The reaction between hydrogrossular and hydrogen chloride (HCl) gas was performed in a fixed bed reactor above 400 degreesC. The hydrogrossular was efficiently reacted with HCl gas in the temperature range of 400 to 950 degreesC and transformed into Ca12Al9.9Si4.05O32Cl5.9 (calcium aluminum chlorosilicate). The crystal structure of the product phase Ca12Al9.9S4.05O32Cl5.9 was cubic, space group I (4) over bar 3d, with unit cell a = 12.0173(1) Angstrom, and was similar to that of wadalite, The structure consists of a framework of (Al,Si)O-4 tetrahedra. A large cavity in the framework accommodates Ca-Cl-Ca linearly coordinated atoms.
