Properties and uses of germanium sulfide

Overview of germanium sulfide GeS2 powder

Germanium disulfide, the molecular formula is GeS2. Unstable, easy to sublime and oxidize at high temperature, decompose in moist air or inert atmosphere, insoluble in water and inorganic acid (including strong acid), soluble in hot alkali, soluble in ammonia gas or vulcanized film.

The density of germanium disulfide is 2.19 g/cm3. The melting point is 800°C. It is a small white powder composed mainly of germanium disulfide (GeS2) particles. Like many closely related metal sulfides, germanium disulfide powder is currently a research topic for many researchers to study its potential in energy storage applications such as solid-state batteries.

The crystals of germanium disulfide are orthogonal. A single cell contains 24 molecules, and its size is: A = 11.66a, B = 22.34A, C = 6.86A. The accuracy is 1/2%. The space group is FDD (C2V19). The eight germanium atoms are located on the double axis. All other atoms occupy a rough position. Determine the 12 parameters involved. Each germanium atom is connected to a tetrahedron of four sulfur atoms with an atomic distance of 2.19A. The angle between the two sulfur bonds is 103°.

High purity germanium sulfide particles GeS2 powder properties

Properties: white powder. Orthogonal crystal structure. The density is 2.19 g/cm3. The melting point is 800°C. Unstable, high-temperature sublimation and oxidation, dissociation in moist air or inert atmosphere. The molten state is a fresh brown transparent object with a density of 3.01g/cm3, insoluble in water and mineral acids (including strong acids), soluble in hot alkali, soluble in ammonia or diamine sulfide, to produce imide germanium. It is made from the mixed gas of germanium powder and sulfur vapor or hydrogen sulfide and sulfur. Used as an intermediate product of germanium metallurgy.

The application of germanium sulfide GeS2 powder

Solid-state batteries: Like many closely related compounds, germanium disulfide is particularly interested in design research and manufacturers in front of them.

In particular, this material has potential value in the production of cathodes for certain types of batteries.

Sulfurized nanoparticles have great potential as high-performance lithium-sulfur batteries.

Electricity: For researchers engaged in energy storage technology, germanium disulfide has the same characteristics, which has certain potential value in the production of other components and materials used in advanced electronic technology.

Catalyst: Like many sulfides, germanium disulfide has the unique potential to produce more complex compounds for high-tech equipment and other chemical reactions.

Optical properties: Like many related materials, nano-scale sulfur provides a large number of unique optical properties, many of which are not yet fully understood.

This makes the material's research interest cover a wide range of industries and fields from electronics to photovoltaics to imaging technology.

American scientists burned a pink "flower" in the furnace. Although it has no fragrance, it can store a lot of energy and is expected to bring about a battery revolution. "Nano flowers" are made from metal germanium sulfide dust, and germanium sulfide is a semiconductor material. Due to its petal shape, although the object is small, it has a large surface area, so it can store a lot of energy.

American scientists have recently designed a miniature battery. This tiny pink nanostructure can completely subvert the traditional battery design and store energy with a unique surface structure. This "nano flower" is made of germanium sulfide (a semiconductor material), and its flower shape has a smaller space and more surface structure to store energy, which will become an ideal energy storage application, such as smartphone battery.

The "nano flower" is only 20-30 nanometers thick and 100 microns long. It has a large surface area with a small spatial structure and can be used to manufacture new smartphone batteries. This breakthrough technology was developed by Linyou Cao of the University of North Carolina and his colleagues. In order to create this nano-flower structure, the research team heated the powdered semiconductor material in a furnace for the first time, Eva and then blow it into a furnace. The lower temperature area makes it settle down layer by layer.
