About Tungsten Telluride Sputtering Target

Telluride IonAmerican Elements specializes in producing high purity Tungsten Telluride Sputtering Targets with the highest possible density High Purity (99.99%) Tungsten Telluride Sputtering Targetand smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. Our standard Sputtering Targets for thin film are available monoblock or bonded with planar target dimensions and configurations up to 820 mm with hole drill locations and threading, beveling, grooves and backing designed to work with both older sputtering devices as well as the latest process equipment, such as large area coating for solar energy or fuel cells and flip-chip applications. We offer all shapes and configurations of targets compatible with all standard guns including circular, rectangular, annular, oval, "dog-bone," rotatable (rotary), multi-tiled and others in standard, custom, and research sized dimensions. All targets are analyzed using best demonstrated techniques including X-Ray Fluorescence (XRF), Glow Discharge Mass Spectrometry (GDMS), and Inductively Coupled Plasma (ICP). "Sputtering" allows for thin film deposition of an ultra high purity sputtering metallic or oxide material onto another solid substrate by the controlled removal and conversion of the target material into a directed gaseous/plasma phase through ionic bombardment. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes. We also produce Tungsten as disc, granules, ingot, pellets, pieces, powder, and rod. Other shapes are available by request.

The number of electrons in each of tungsten's shells is [2, 8, 18, 32, 12, 2] and its electron configuration is [Xe] 4f14 5d4 6s2. Tungsten Bohr ModelThe tungsten atom has a radius of 139 pm and a Van der Waals radius of 210 pm. Tungsten was discovered by Torbern Bergman in 1781 and first isolated by Juan José Elhuyar and Fausto Elhuyar in 1783. In its elemental form, tungsten has a grayish white, lustrous appearance. Elemental TungstenTungsten has the highest melting point of all the metallic elements and a density comparable to that or uranium or gold and about 1.7 times that of lead. Tungsten alloys are often used to make filaments and targets of x-ray tubes. It is found in the minerals scheelite (CaWO4) and wolframite [(Fe,Mn)WO4]. In reference to its density, Tungsten gets its name from the Swedish words tung and sten, meaning heavy stone.


See more Tellurium products. Tellurium (atomic symbol: Te, atomic number: 52) is a Block P, Group 16, Period 5 element with an atomic radius of 127.60. Tellurium Bohr ModelThe number of electrons in each of tellurium's shells is 2, 8, 18, 18, 6 and its electron configuration is [Kr] 4d10 5s2 5p4. Tellurium was discovered by Franz Muller von Reichenstein in 1782 and first isolated by Martin Heinrich Klaproth in 1798. In its elemental form, tellurium has a silvery lustrous gray appearance. The tellurium atom has a radius of 140 pm and a Van der Waals radius of 206 pm. Elemental TelluriumTellurium is most commonly sourced from the anode sludges produced as a byproduct of copper refining. The name Tellurium originates from the Greek word Tellus, meaning Earth.
