Abstract
Samples have been prepared at 1 kbar PH (sub 2O) for the join richterite- titanium richterite in the system K (sub 2) O-Na (sub 2) O- CaO-MgO-TiO (sub 2) -SiO (sub 2) -H (sub 2) O. Infrared and Raman spectroscopic techniques were used to define Ti (super 4+) sites and to characterize structural variations caused by the incorporation of Ti.
