New Hampshire sapphire and silicon crystal growth company

Same company supplies furnaces for both sapphire and silicon crystal growth; thousands of furnaces sold to Chinese solar industry.

The company that grows this aluminum oxide, or builds the equipment for it, is up here in New Hampshire. The equipment is about a quarter the size of this room and about as tall as this room. The melting temperature of aluminum oxide is about 2,000 centigrade, so it gets pretty hot.
