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)是一種準金屬，元素符號為Te。其名源自tellus，意為“土地”，1782年米勒·馮·賴興施泰因(F.J.Müller von Reichenstein)發現。碲為斜方晶系銀白色結晶，溶于硫酸、硝酸、王水、氰化鉀、氫氧化鉀；不溶于冷水和熱水、二硫化碳。高純碲以碲粉為原料，用多硫化鈉抽提精制而得，純度為99.999%。供半導體器件、合金、化工原料及鑄鐵、橡膠、玻璃等工業作添加劑用。
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.
