The Fabricated Products Group of H.C. Starck Solutions has several years of experience in the manufacture of high performance materials, particularly refractory metals like rhenium, niobium, tantalum, tungsten and molybdenum. Silicon Sputtering Target
As one of the world’s largest producers of tungsten, tantalum metal and molybdenum metal powder, H.C. Starck Solutions supplies various solutions for the thin film industry, for applications such as photovoltaic cells for solar power.
H.C. Starck Solutions has the capability to extract many refractory metals through a recycling process. The recycled tungsten, tantalum and molybdenum metals from spent sputter targets is just as high in quality and purity as that of the raw material.
The use of recycled material helps to conserve natural resources, and reduces energy consumption, thus serving as a vital part of a stable raw material supply.
The key properties of refractory metals used for thin film applications are:
The tantalum products supplied by H.C. Starck Solutions have a uniform, high density microstructure and controlled texture that ensures superior sputtering behavior and uniform sputtering rates.
The products are available in six different grades of tantalum, with available purities ranging from 99.95% to 99.995%, to meet the requirements of different applications. Tantalum is widely used in chemical processing and the pharmaceutical industry, in addition to thin film PVD applications.
Tungsten is supplied in purity levels of up to 99.99%, in pure and alloy form. Tungsten's high density means that it is widely applied in the thin film coating industry.
H.C. Starck Solutions supplies molybdenum in the form of powder and also as finished parts. It finds use in LCD displays, integrated circuits and photovoltaic solar cells.
Niobium thin film is commonly used for optical applications. Like tantalum, this metal also has high resistance to chemical attack and corrosion.
Titanium is a highly corrosion resistant metal with good electrical resistivity. It can be used in optical coatings, solar cells and LCDs.
H.C. Starck Solutions also produces other materials like molybdenum-titanium, molybdenum-niobium-zirconium, molybdenum-tungsten, nickel-chromium, and nickel-vanadium.
The refractory metals are used in a number of industries as given below:
As a worldwide leader in refractory metals right from inorganic chemicals to finished product, H.C. Starck Solutions features state of the art laboratories and highly skilled professionals to develop new and innovative products for the future. The Thin Film Materials Lab of the company is equipped with magnetron sputtering equipment, film stress tester, adhesion tester, vacuum annealing equipment, spectrophotometer, 4-point resistivity probe, and scanning electron microscopes.
For thin-film PV applications, H.C. Starck Solutions delivers rotary and planar sputtering target materials made of high-purity molybdenum for CdTe and CIGS based solar cells, and rotary NiV targets used for Si thin-film solar cells. The company also produces niobium, titanium and other materials.
