Is germanium magnetic?

Abstract. The magnetic susceptibility of highly doped germanium has been measured between 300°K and 1.3°K. The contribution of the carriers to the susceptibility has been derived from the data.

Is germanium a metal or nonmetal?

Most elements are either metals or nonmetals. Germanium falls in the same group as carbon and silicon, but also as tin and lead. Germanium itself is classified as a metalloid.

What is the property of germanium?

Pure germanium is a hard, lustrous, gray-white, brittle metalloid. It has a diamondlike crystalline structure and it is similar in chemical and physical properties to silicon. Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid.

How is germanium mined?

Today, germanium is primarily obtained from the smelting of zinc ores and from the byproducts of burning certain types of coal. The largest use of germanium is in the semiconductor industry.

What are 3 uses for germanium?

The most common use of germanium is as a semiconductor. Germanium is used in transistors and in integrated circuits. It is used as an alloying agent and as a catalyst. It is also used in infrared spectroscopes and infrared detectors.

Is germanium toxic to humans?

Germanium is not an essential element. Its acute toxicity is low. However, at least 31 reported human cases linked prolonged intake of germanium products with renal failure and even death.

Where is germanium used in everyday life?

In addition to its applications in electronic devices, germanium is used as a component of alloys and in phosphors for fluorescent lamps. Because germanium is transparent to infrared radiation, it is employed in equipment used for detecting and measuring such radiation, such as windows and lenses.

What is germanium most commonly used for?

Is germanium safe to wear?

Inorganic (elemental) germanium is LIKELY UNSAFE. This includes certain compounds such as germanium oxide. There have been more than 30 reports of kidney failure and death linked with use of these forms of germanium. It builds up in the body and can damage vital organs such as the kidneys.

Is germanium good for the body?

Despite serious safety concerns, germanium is used for heart and blood vessel conditions, including high blood pressure, high cholesterol, and heart disease; for eye conditions, including glaucoma and cataracts; and for liver conditions, including hepatitis and cirrhosis.

What is a real life example of germanium?

Why is germanium bad for you?

What kind of bracelets have germanium on them?

In design, germanium bracelets may be as simple or complex as the wearer would like. Some designs involve titanium bracelets that are studded with germanium elements. There are versions of the bracelet that are designed specifically for men, while others are designed for women.

How is germanium a hazard to human health?

Some of germanium’s artificially produced compounds are quite reactive and present an immediate hazard to human health on exposure. For example, germanium chloride and germane (GeH4) are a liquid and gas, respectively, that can be very irritating to the eyes, skin, lungs, and throat.

How are germanium dioxide and germanium monoxide obtained?

Chemistry. Two oxides of germanium are known: germanium dioxide ( GeO 2, germania) and germanium monoxide, ( GeO ). The dioxide, GeO 2 can be obtained by roasting germanium disulfide ( GeS 2 ), and is a white powder that is only slightly soluble in water but reacts with alkalis to form germanates.

How does germanium react with sulfuric acid and nitric acid?

Chemistry. Germanium is insoluble in dilute acids and alkalis but dissolves slowly in hot concentrated sulfuric and nitric acids and reacts violently with molten alkalis to produce germanates ( [GeO 3]2− ). Germanium occurs mostly in the oxidation state +4 although many +2 compounds are known.
