The use of solar energy is of increasing importance. Low iron soda-lime silica flat glass, produced by using the float process, is used for such solar energy plants. The surface properties and the corrosion resistance of these float glasses are examined in this work. In solar application, the transmissivity of glasses must be high and stable over...

In basaltic glass from the southern Mid-Atlantic-Ridge conducive environmental conditions for biogenic weathering resulted in excellent preserved microbial morphologies on glass surfaces. The distinct glass interface and open spaces between palagonite sheet and glass indicate a dissolution-reprecipitation mechanism of glass alteration potentially s...

Due to the application of soda-lime-silica glasses for solar conversion systems, a benchmarking of glasses from various manufacturers worldwide is a useful tool to evaluate the differences in quality with respect to their mechanical resistance. Therefore experiments on crack resistance of glass according to Kato et al. (2010) have been performed. K...

Nanocrystalline NaNO 3 enclathrated microporous material with intermediate structure (INT) between the well known zeolites sodalite (SOD) and cancrinite (CAN) can be prepared from aluminosilicate gels under addition of high amounts of NaOH and NaNO 3 using low temperature conditions (333 K) within reaction periods of 1-96 h. The nanocrystalline pro...
