Refined bismuthRefined bismuth metal is obtained by melting and smelting on the basis of bismuth metal, which can be used as a safer and greener basis to help ensure the quality of products.
Gallium metalA rare blue white trivalent metallic element that is hard and brittle at low temperatures and melts as soon as it exceeds room temperature. When it solidifies, it expands, usually obtained as a byproduct of extracting aluminum from bauxite or zinc from zinc ore, with the element symbol Ga.
indiumIndium is a metallic element with the symbol In and atomic number 49, located in the IIIA family of the fifth cycle of the periodic table. Its elemental substance is a silver white metal with a slight hint of light blue, which is very soft and can be scratched with nails. Strong plasticity, ductility, and can be compressed into sheets. Metal indium is mainly used as a raw material for manufacturing low melting alloys, bearing alloys, semiconductors, and electric light sources.
碲(tellurium)是一种准金属，元素符号为Te。其名源自tellus，意为“土地”，1782年米勒·冯·赖兴施泰因(F.J.Müller von Reichenstein)发现。碲为斜方晶系银白色结晶，溶于硫酸、硝酸、王水、氰化钾、氢氧化钾；不溶于冷水和热水、二硫化碳。高纯碲以碲粉为原料，用多硫化钠抽提精制而得，纯度为99.999%。供半导体器件、合金、化工原料及铸铁、橡胶、玻璃等工业作添加剂用。
telluriumTellurium is a quasi metal with the elemental symbol Te. Its name comes from tellus, meaning "land", discovered by F.J.M ü ller von Reichenstein in 1782. Tellurium is a silver white crystal in the rhombic crystal system, soluble in sulfuric acid, nitric acid, aqua regia, potassium cyanide, and potassium hydroxide; Insoluble in cold and hot water, carbon disulfide. High purity tellurium is obtained by extracting and refining tellurium powder with sodium polysulfide, with a purity of 99.999%. Used as additives for semiconductor devices, alloys, chemical raw materials, and industries such as cast iron, rubber, and glass.
Refined seleniumThe appearance of refined selenium can be powder or granules, or it can be in the form of ingots. Selenium ingots are in the form of ingots and should generally be refined selenium. Generally, selenium powder sold as a finished product refers to refined selenium, with a purity of over 99.9%.
Selenium dioxideSelenium dioxide, a type of oxide with the chemical formula SeO2, is a white crystalline powder with a yellow green vapor. It is soluble in water and polar organic solvents and is used as an oxidant, catalyst, chemical reagent, and raw material for the production of various inorganic selenium compounds.
