27JUN06, 28JUN06 and 06JUL06 June 27th. A polished sapphire sample was used in 160 μS/cm KCl solution. The aging of KCl was observed at pH 5.5. June 28th. A polished sapphire sample was pre-treated in pH 11 solution and used in 138 μS/cm KCl solution. The aging of sapphire in KCl was observed at pH 5.5 July 6th. A polished sapphire sample was sonicated. It was then pre-treated in pH 11 solution and used in 148 μS/cm KCl solution. The aging of sapphire in KCl was observed at pH 5.5. All plots proved to be reproducible over time. |
