The formation of CA 2 in the molar mix of CA and A occurs by diffusion of A into the CA matrix. The reaction is phase boundarycontrolled. The activation energy for CA,~ formation in the temperature range of 1350-1450 C is 33.40 Kcal mole "1. The activation ~'ree energy and activation entropy is foun
Various members of the KA1Si3Os--BaA12Si~O s feldspar series are hydrothermally synthesized. Cellparameters of these are calculated from diffraetometer patterns and found to be similar to those of Gay and Roy. A variation diagram is constructed correlating Cncontent and values of AFeKa(20(nl)CaF2--2
