Strontium Lump

Product Overview
Strontium lump is a silver-white, soft metal known for its strong reactivity and relatively high melting point. With a molecular weight of 87.62 and a density of 2.63, strontium is highly reactive and easily oxidizes in air, forming a yellow oxide layer on its surface. During handling, strontium can self-ignite and release hydrogen gas and a large amount of heat when exposed to water, creating a deep red flame. This metal is widely used in various industrial applications, especially as an alloying additive, deoxidizer, and reducing agent. Strontium's unique chemical properties make it valuable across multiple fields.

Features

• High Reactivity: Strontium is highly reactive, particularly in air and water, making it ideal for use in special chemical reactions.
• High Melting Point: With a melting point of 769°C, strontium is suitable for high-temperature industrial environments.
• Surface Oxidation: Strontium quickly oxidizes in air, forming a yellow oxide layer that enhances its oxidation resistance.
• Red Flame Combustion: When burned, strontium emits a distinctive deep red flame, offering unique visual effects.

Applications
Strontium lumps are used in a variety of industries, including:

• Aluminum and Magnesium Alloys: As a modifier for aluminum alloys and a grain refiner for magnesium alloys, improving the mechanical properties of the alloys.
• Steel Industry: As an excellent deoxidizer and desulfurizer, enhancing the quality of steel.
• Chemical Industry: Used as a reducing agent for refractory metals, facilitating various chemical reactions.
• Vacuum Technology: As a highly efficient getter, strontium is widely used in vacuum technology.
• Foundry Industry: Strontium is used to improve the mechanical properties of thin-walled cast iron parts, increasing the durability and strength of castings.
