Název v původním jazyce

Complex study of e-glass corrosion

Popis výsledku v původním jazyce

Both the static and dynamic corrosion tests of E-glass were used for different conditions -temp., glass surface to soln. vol. ratio (S/V), soln. flow rate (F) and F/S ratio. Results obtained for glass fibers were compared with the ones for glass grains and planar samples. Evaluation of exptl. results by kinetic model shows that the change of glass surface should be taken into account in the case of fibers corrosion. The total incongruent process of dissoln. could be explained as congruent dissoln. of glass accompanied by back pptn. of SiO2 or silicates. In most cases, more then 90% of SiO2 ppts. back. The second possible explanation, i.e. SiO2 network dissoln. accompanied by selective leaching of Ca, B and Al, is not very probable. The glass sample shape can influence the estn. of dissoln. rate. Up to now, with existing kinetic models, the dissoln. rates evaluated from expts. with different shapes of glass (fibers, grains, planar) cannot be used as materials properties.
