Tungsten Disilicide Powder

Product Code : AL-WSi2-CU-PO

Tungsten disilicide (WSi2) powder is a black-gray powder with a tetragonal crystal structure, which is often used as an electric shock material in the field of microelectronics. It has the advantages of high melting point, good stability and low resistivity. Heeger Materials can offer high quality tungsten disilicide (WSi2) powders at competitive prices.

In most volumes, tungsten silicide is usually immediately available. Ultra-high purity, high purity, sub-micron and nano-powder forms can be considered. ATT produces a number of standard grades where applicable, including the Mil Spec(military grade); ACS, reagents and technical grades; Food, agriculture and pharmaceutical grades; Optical grades, USP and EP/BP(European Pharmacopoeia/British Pharmacopoeia), and follow applicable ASTM test standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information and reference calculators for converting relevant units of measurement are available.

ATT is a professional supplier of tungsten oxide (WO3) sputtering targets, we also produce optical discs, pellets, ingots, balls, sheets, powders, rods, wires, sputtering targets and many other forms and custom shapes. Other shapes are available upon request.

Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.
