Discontinued (Discontinued) ST6570 Beryllium Sputtering Target Be

Beryllium Sputtering Target Be Description

Beryllium Sputtering Target (Be) is a high-performance material characterised by its exceptional combination of low density (1.85 g/cm³), high stiffness, excellent thermal conductivity (~200 W/m-K), and low thermal expansion coefficient (~11.3 × 10⁻⁶/K). With a typical purity of 99.9% or greater, it ensures chemical stability and uniformity during the sputtering process. Beryllium also offers remarkable mechanical strength and can be precisely machined into various shapes and sizes to accommodate different deposition systems. Its high thermal conductivity enables efficient heat dissipation, while its dimensional stability during temperature fluctuations enhances film adhesion and consistency. The surfaces of the targets are finely ground to achieve outstanding smoothness and uniform film thickness. All materials are vacuum-sealed to prevent oxidation and contamination.

Beryllium (Beryllium) Element Overview

Beryllium is a lightweight metallic element (atomic number 4, symbol Be), discovered in 1798 by the French chemist Vauclain and named after the mineral beryl. As the second lightest metal in the periodic table (with a density of 1.85 g/cm³, after Lithium), Beryllium displays remarkable properties that are disproportionate to its weight: it has a modulus of elasticity of 287 GPa, making it six times tougher than steel, and an extremely high thermal conductivity (200 W/m-K, after Silver, Copper, and Gold). This unique combination of "low density, high stiffness and high thermal conductivity" makes it a valuable material in extreme industrial scenarios, but its toxicity, high cost, and difficult processing significantly limit its range of applications.

Core Properties and Scientific Value

Penetration advantage of low atomic number

The Beryllium nucleus contains only four protons (Z=4) and has a very low absorption rate for X-rays and neutrons. This property makes it a core material for synchrotron radiation devices, X-ray windows, and an ideal neutron-reflecting layer in nuclear reactors. For instance, if the X-ray detector window of a medical CT scanner were made of Aluminium or Glass, the image resolution would be significantly impaired, whereas a Beryllium window at an extremely small thickness (<1 mm) can achieve nearly lossless radiation penetration.

Stability in Extreme Environments

Beryllium has a melting point of 1,287 °C and maintains a protective layer of beryllium oxide (BeO) at high temperatures, providing corrosion resistance that far exceeds that of lighter metals like Aluminium and Magnesium. This property has led to its use in high-temperature resistant coatings for rocket nozzles and casing materials for nuclear fuel rods. The US Mars rover Curiosity employs Beryllium alloys for its radioisotope thermoelectric generators (RTGs) to withstand extreme temperatures and radiation on Mars.

An Indispensable Role in Aerospace

When constructing satellites and space telescopes, the high specific stiffness (stiffness/density) of Beryllium resolves the tension between low weight and structural strength. For example, the 18 primary mirrors of the James Webb Space Telescope are made of Beryllium - a mirror that deforms minimally in the deep-space environment at -240 °C, while conventional glass or ceramic would distort the image due to thermal expansion and contraction. Additionally, the inertial navigation gyros of intercontinental ballistic missiles contain Beryllium components ensuring shape stability at high speeds.

Applications and Challenges

Industrial applications of Beryllium are focused heavily on high-quality "must-have" areas:

Nuclear and defence industry: Neutron reducers, atomic bomb detonators (utilising the photo-neutron reaction properties of Beryllium);

Precision optics: High-energy laser mirrors, mirror bases for infrared thermal imaging cameras;

Special alloys: Beryllium-Copper alloys with a 2% Beryllium content combine high strength with spark-free characteristics for oil and gas drilling tools. Beryllium-Copper alloys with a 2% Beryllium content combine high strength with spark-free characteristics and are used for oil and gas drilling tools and explosion-proof devices.
