IR Measurements of Intracrystalline Water in Quartz at High Temperatures. Time-Dependent Spectral Change of OH Species
In-situ IR measurements were conducted with varying heating duration to study a time-dependent changes (i) an increase of the 3379cm<SUP>-1</SUP> absorption peak at room temperature (RT) assigned to OH associated with Al<SUP>3+</SUP> substitution for Si (OH (Al) ) and (ii) a decrease of the 3482cm<SUP>-1</SUP> peak (RT) assigned to OH (Al) including a influence of Li<SUP>+</SUP> interstitial defects or Li-O-Al as acharge compensating role. These (i) and (ii) are consideredto be dueto an exchangeof Li<SUP>+</SUP> with H<SUP>+</SUP>, since theseions become more diffusive at higher temperatures.
