<DIV>Dear Psubbers</DIV>
<DIV dir="ltr">I found that ALON (Aluminium oxynitide) (transparent aluminium) is already being used in several aplication. This ceramic is very promising. I could not find anything about its use in deep sea exploration. Does somebody knows if is already being used in undersea cameras, submersibles or Rovs?</DIV>
<DIV dir="ltr">If the price is not to high this would be ideal for our community.</DIV>
<DIV dir="ltr">Best wishes</DIV>
