Tonight: watch massive optical sapphire crystals being grown
Tonight on the Science Channel, Rubicon Technology (Franklin Park, IL) will demonstrate how the company makes some of the world's largest sapphires in a segment of the "How Do They Do It?" show. The segment will show aluminum oxide heated to 3000 K and then formed into sapphires weighing in at as much as 400 lbs. A sapphire will be cut into cores, which will then be sliced into ultrathin wafers used to make LEDs as well as high-strength, rugged optical windows intended for military optical sensors and other devices.
