Fig. 1From: 29Si solid state NMR and Ti K-edge XAFS pre-edge spectroscopy reveal complex behavior of Ti in silicate meltsUpper portion of the SiO2–Na2O–TiO2 phase diagram. Our experiments were performed along the NS8 and NS4 joins. Experimental bulk compositions are denoted with black circles. Thin black lines are liquidus isotherms, and thick black lines are liquidus phase boundaries. (modified from Glasser and Maar 1979)Back to article page
