Abstract

A microwave-assisted structure-conversion (MASC) method was used to obtain photochromic hackmanites (M,Na)(8)Al6Si6O24(Cl,S)(2) (M: Li, Na, and K) in a fast (12 to 20 min) one-step process. Structural conversion from Zeolite A to hackmanite minerals has been proven to be very effective through an aluminosilicate crystalline intermediate. Photochromism is observed with both UV and X-ray (CuK) excitation. (AU)
