Tellurium Bromide powder is a compound powder consisting of the elements tellurium and bromine, the colour of which may vary depending on the specific composition (e.g. TeBr₄, etc.), which is chemically active and plays a role in the fields of chemical synthesis and photovoltaic materials.
Properties
Appearance: Yellow to orange crystalline powder.
Density: Solid density of 4.3 g/cm³, the relatively high density makes it necessary to take care to prevent precipitation and accumulation during storage and transport.
Melting Point: Approximately 388°C (661 K), at which temperature it changes from a solid to a liquid, providing a reference temperature for heat treatment during material preparation.
Boiling point: Decomposes at 420°C (693 K), rather than having a defined boiling point as is usually the case with substances, which means that near this temperature its chemical structure changes and it decomposes to produce other substances.
Crystal structure: It belongs to the monoclinic crystal system. This crystal structure determines the arrangement and spatial symmetry of the atoms within it, which in turn affects its physical and chemical properties.
Solubility: it has high water solubility and can be dissolved in water to form corresponding ionic solutions. This makes it potentially valuable in some chemical processes that require aqueous phase reactions, but also requires attention to storage and use in humid environments to prevent dissolution or deterioration due to absorption of moisture in the air.
Chemical reactivity: it has certain chemical reactivity, as a halide, it can react with other substances, for example, it may react with some reducing agents and be reduced to tellurium monomers; it may react with some metal ions under acidic conditions in a substitution reaction, and so on.
Applications
Chemical synthesis field:
Preparation of elemental tellurium: it can be used as a raw material for the preparation of tellurium monomers, and pure tellurium can be obtained by separating the tellurium elements from tellurium bromide through further chemical reactions or purification processes. Tellurium has important applications in semiconductors, solar cells, etc., so tellurium bromide is an important precursor for the production of elemental tellurium.
As a reaction reagent: it participates in some specific chemical reactions as a brominating agent or catalyst to help introduce the element bromine or to facilitate the reaction, but the specific reaction and application scenarios need to be determined according to the specific needs of experiments and research.
Materials Science Field:
Crystal growth: used in the growth process of certain crystalline materials to provide tellurium and bromine elements to the crystals, which affect the structure and properties of the crystals. For example, in the growth of some special semiconductor crystals or optical crystals, tellurium bromide can be used as a dopant or raw material to improve the electrical and optical properties of the crystals.
Thin film preparation: through sputtering, evaporation and other techniques, tellurium bromide powder is made into thin film materials, and these films can be used in electronic devices, optical devices and other fields, such as the preparation of semiconductor thin films, optical coatings and so on.
Scientific research field:
Analysis and detection: in chemical analysis and material analysis, it can be used as a standard or reference substance for detecting and analysing the composition and properties of other substances. For example, in spectral analysis, chromatographic analysis and other techniques, tellurium bromide can be used as internal standard or calibrator to improve the accuracy and reliability of analysis.
Scientific research: As a special compound, tellurium bromide can be used to explore new chemical reactions, physical phenomena and material properties in scientific research in chemistry, physics and materials, providing experimental basis and data support for the development of scientific theories.
