gallium bead9c90-50ca-4b54-a4cd-ee384338020c
gallium
Gallium is a silver-white metal. The density is 5.904 g/cm3. The melting point is 29.78°C. The boiling point is 2403°C. Due to the complex structure of stable solids, pure liquids have a significant tendency to overcool and can be kept in an ice bath for several days without crystallization. It is soft, brittle, and stable in the air. It is soluble in acid and alkali when heated; it reacts violently with boiling water, but only slightly reacts with water at room temperature. It can interact with most metals at high temperatures. When it is converted from liquid to solid, the expansion rate is 3.1%, and it is suitable to be stored in a plastic container. It swells when it solidifies, and is usually obtained as a by-product of extracting aluminum from bauxite or zinc from zinc ore, or it is often dispersed in small amounts in aluminum ore, sphalerite and other ores in nature. Extracted from bauxite.

Tellurium Ingot
Tellurium is a metalloid, and the element symbol is Te. The name comes from tellus, which means "land", discovered by F.J.Müller von Reichenstein in 1782. Tellurium is an orthorhombic silver-white crystal, soluble in sulfuric acid, nitric acid, aqua regia, potassium cyanide, potassium hydroxide; insoluble in cold water, hot water, and carbon disulfide. High-purity tellurium is obtained from tellurium powder as raw material, extracted and refined with sodium polysulfide, with a purity of 99.999%. Used as additives in semiconductor devices, alloys, chemical raw materials, cast iron, rubber, glass and other industries.

tellurium
Metal tellurium, high-purity tellurium is an off-white metallic luster prismatic crystal or powder, density 6.24g/cm3, melting point 449.5°C, boiling point 988°C, soluble in concentrated nitric acid, concentrated sulfuric acid and strong alkali, not at room temperature ~ Oxygen effect is mainly used in the preparation of semiconductor compounds, thermoelectric conversion elements, piezoelectric transistors, infrared detector elements, light control elements, light deflection elements, and special metal materials. It is widely used in civil, military, aerospace, and electronics fields.
Bismuth Ingot
Bismuth Ingot
Bismuth is a metal element with element symbol Bi and atomic number 83. It is located in the V A group of the sixth period of the periodic table. The simple substance is silver-white to pink metal, brittle and easily crushed, and the chemical properties of bismuth are relatively stable. Bismuth exists in the form of free metals and minerals in nature.

Bismuth Oxide
High-purity bismuth oxide is a yellow heavy powder or monoclinic crystal. There are three crystal types of bismuth oxide, namely equiaxed, monoclinic and tetragonal crystal types, and only the equiaxed crystal type is easy to physically refine and process into ultra-fine high-purity oxide bismuth. It is the basic material of many high-tech products such as electronic information.

bismuth
High-purity bismuth is mainly used in the nuclear industry, aerospace industry, electronics industry and other sectors. Because bismuth has semiconductor characteristics, its resistance decreases with increasing temperature at low temperatures. In terms of thermoelectric cooling and thermoelectric power generation, Bi2Te3 and Bi2Se3 alloys and Bi-Sb-Te ternary alloys attract the most attention. In-Bi alloy and Pb-Bi alloy are superconducting materials. Bismuth has a low melting point and high density, low vapor pressure, and small neutron absorption cross section. It can be used in high-temperature atomic reactors.
