Boron

Boron is a hard, dark metalloid that is never found pure in nature. It is mined as borate minerals such as borax, mostly in Turkey and the United States, from the beds of ancient dried-up lakes.

In the television it does several jobs. As boron trioxide it goes into heat-resistant glass, including the display glass of the screen. A small amount locks the crystal structure of the neodymium magnet in each speaker. And in chips, a trace added to the silicon ingot sets its electrical type, while boron implanted into doped silicon creates the p-type regions that, paired with n-type ones, make transistors work.
