Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
There's another problem, which is how increased demand might change the price. If a material is produced from an ore, it may be easy to ramp up production. Gallium, though, is mostly produced as a by-product of aluminium production. Unless other sources are developed (the flue-ash mentioned in the article?), the production of gallium will be limited to being a small fraction of the production of aluminium -- aluminium ore contains about 50 parts per million. On the other hand, it may be that most of this potential by-product isn't extracted at present, which would leave more room for growth in production.

Total annual world production a few years ago was estimated to be 61 tons, so growth would presumably have to be huge, in percentage terms.
