Magnesium metal

Magnesium Sputtering Target is a high-purity metal target used in physical vapor deposition (PVD) processes to deposit a thin layer of magnesium onto various substrates. The sputtering process involves bombarding the magnesium target with high-energy ions, causing the target material to eject atoms or molecules, which then condense onto the substrate surface, creating a thin film.

Physical Properties:

Formula: Mg

Atomic Number: 12

Appearance: Magnesium sputtering targets are typically metallic and have a shiny silver-gray color.

Purity: The targets are usually of very high purity, typically around 99.9% or higher, to ensure high-quality film deposition.

Size and Shape: Commonly produced in circular, rectangular, or custom shapes, depending on the specific sputtering system and application requirements. Standard diameter sizes range from 2 inches to 4 inches, but they can be customized for larger systems.

Density: Approximately 1.74 g/cm³.

Melting Point: Around 650°C (1,202°F), which is relevant when considering deposition temperatures.

Applications:

Thin Film Coatings: Magnesium sputtering targets are used to create thin films of magnesium on substrates for applications such as optics, sensors, and electronic components.

Magnesium Alloys: They are used in the deposition of magnesium alloy films, which are then used in applications like lightweight coatings, corrosion-resistant surfaces, and structural materials.

Semiconductor Manufacturing: Magnesium sputtering targets can be employed in semiconductor fabrication, where magnesium films can serve as a gate dielectric or in the creation of various layers in devices.

Photovoltaic Cells: Magnesium films are sometimes used in solar cells to improve their electrical properties and efficiency.

Magnetic and Optical Coatings: Magnesium sputtering targets can also be used for applications requiring specific optical or magnetic properties, such as anti-reflective coatings or magnetic films.

Battery Technology: Thin magnesium films are being researched for use in batteries, particularly in lithium-ion or magnesium-ion batteries.

Safety and Storage:

Flammability: Magnesium sputtering targets are reactive and should be stored away from heat sources, sparks, or open flames to avoid combustion. They should also be stored in dry conditions to prevent oxidation.

Handling Precautions: When handling magnesium sputtering targets, safety equipment such as gloves and protective eyewear should be worn. It’s important to avoid direct contact with moisture, and proper ventilation is required to avoid accumulation of combustible gases.

Storage: Store magnesium sputtering targets in cool, dry conditions, away from sources of moisture and direct sunlight. Ensure that the storage area is free from any flammable materials.
