Strontium metal granules are chemically active strontium metal granules with a silvery-white metallic luster and a density of approx. 2.64 g\/cm\u00b3, which have important applications in the electronics industry and alloying materials, and need to be stored in sealed containers to prevent oxidation.<\/p>\n
Properties<\/p>\n
Chemical formula: Sr<\/p>\n
Appearance: Silver-white metallic luster particles.<\/p>\n
Density: approx. 2.64 g\/cm\u00b3, relatively low, which is advantageous in applications where material weight is important.<\/p>\n
Melting point: 769\u00b0C, at which temperature the strontium metal particles change from solid to liquid.<\/p>\n
Boiling point: 1384\u00b0C, at which point it changes to a gaseous state.<\/p>\n
Hardness: soft, Mohs hardness is about 1.5, the relatively soft texture makes it in some specific processing or application scenarios need to pay attention to avoid excessive extrusion or friction leading to particle deformation or fragmentation.<\/p>\n
Chemical activity: strong chemical activity, easily oxidized in the air, the surface will quickly form a film of strontium oxide, so usually need to be stored and used in an inert gas protection or vacuum environment to prevent further oxidation and deterioration.<\/p>\n
Applications<\/p>\n
Electronic industry: In the manufacture of electronic devices, it can be used as a dopant in the preparation of semiconductor materials. By introducing strontium metal particles into the semiconductor lattice, it can adjust the electrical properties of semiconductors and improve the performance and stability of electronic devices.<\/p>\n
Alloy materials: can form alloys with other metals to improve the performance of alloys. For example, the strontium aluminum alloy formed with aluminum has high strength and corrosion resistance, and can be used as structural material in aerospace and automobile manufacturing.<\/p>\n
Chemical Synthesis: As a strong reducing agent, it can participate in a variety of chemical reactions and be used to synthesize some compounds with special properties. In addition, in some organic synthesis reactions, strontium metal particles can also be used as catalysts or reaction intermediates to promote the reaction.<\/p>\n
Absorbent: Due to its strong adsorption capacity for oxygen, nitrogen and other gases, it can be used as an absorbent in vacuum systems or electronic tubes and other devices to absorb residual gases and improve the vacuum and performance of the device.<\/p>\n","protected":false},"excerpt":{"rendered":"
