The abundance of in the Earth's crust is small—generally less than 19 parts per million. does not exist in elemental form in nature, and the few high- minerals that do occur are too rare to serve as a primary source of the element.

usually cannot be found in nature. It exists in the earth's crust, where its abundance is about 16.9 ppm. It is extracted from bauxite and sometimes sphalerite. can also be found in coal, diaspore and germanite.

In nature, is difficult to find. It makes up about 0.0019 percent of Earth's crust. And it is never found on its own! Instead, it has to be separated from other materials through a process called smelting.

* can affect you when breathed in. * is a CORROSIVE CHEMICAL and contact can severely irritate and burn the skin and eyes with possible eye damage. * Breathing can irritate the nose and throat causing coughing and wheezing. * may damage the liver and kidneys.

The current price of is $601.70 per kg.

It has particular properties that make it very versatile. It has important uses in Blu-ray technology, mobile phones, blue and green LEDs and pressure sensors for touch switches. readily alloys with most metals. It is particularly used in low-melting alloys.

is the 32nd most abundant element and constitutes 0.0005% of the Earth's crust. It is found most commonly in association with zinc, germanium, and aluminum and is found primarily in the mineral germanite.
