  1. Tests of Anomet Aluminum Reflectors in Ultrapure Water C. Lu and K.T. McDonald Princeton University (Jan. 5, 2007) C. Lu & K. McDonald, Princeton University

  2. Anolux Stucco MIRO New surface In the water for 75 days Bad! C. Lu & K. McDonald, Princeton University

  3. Anolux III New surface In the water for 75 days Bad! C. Lu & K. McDonald, Princeton University

  4. Anolux MIRO Silver In the water for 75 days Bad! C. Lu & K. McDonald, Princeton University

  5. Anolux Hammertone In water for 75 days New C. Lu & K. McDonald, Princeton University

  6. Anolux Hammertone More pictures for the in-water sample C. Lu & K. McDonald, Princeton University

  7. Anolux MIRO IV In water for 75 days Better than others, at least after 75 days no noticeable corrosion found on the surface. C. Lu & K. McDonald, Princeton University

  8. Ordinary aluminum (6061?) Above water In water for 35 days C. Lu & K. McDonald, Princeton University

  9. What next • Although the Anolux MIRO IV is better than others, but it is only in the water for 75 days, we’ll continue the test. • Use SEM/EDX system to do the chemical analyses of sample’s surface. Energy dispersive X-ray (EDX) analysis can use the characteristic spectrum of x-rays emitted by the specimen to obtain information about its elemental composition. That will tell us why some sample is better than others, what chemical components are lost in the water, etc. That will help us to choose the right building material. • Test every material that will put into the water, make sure all of them are compatible with the water. • Monitor the water quality for its pH, resistivity in long term.
