Eric, loose again. It is similar to the hall process and takes place in a salt melt, but I have no details. Al takes lots of power too, and yet it is $1 per pound. I suspect the main use will be in loaded dice, as Ti cannot be detected in dice, even by the water test. Bill

.........very corrosion resistant, very like Aluminum in that respect. Actually, pure aluminium is very reactive (in the chemical sense). What makes it resistant to corrosion is the thin transparent layer of very stable aluminum oxide (Al2O3) that clings tenaciously to its surface. If this surface layer is penetrated or removed, then the aluminum is no longer resistant to corrosion. For example, just place a sheet of aluminum foil in a mercury (II) chloride solution, then take it out and place it on a paper towel in the open air. Then the aluminum will crackle softly as it corrodes to give Al2O3 and a lot of heat will be liberated.
