Company Description
Tungsten Powder
Our tungsten powders are designed specifically to provide the high purity
and particle size uniformity required by manufacturers of metallic tungsten products and cemented tungsten carbide.
Particle size and particle size distribution are critical factors in the physical and mechanical properties of products produced from powder metals. OSRAM SYLVANIA maintains Fisher Sub Sieve particle size within tenths of a micrometer by precise control of the manufacturing process.
While wolframite is the most commonly used ore concentrate, OSRAM has the capability to
process other type ores to recover pure tungsten and to remove all objectionable impurities. During the chemical processing, critical control points are monitored to assure the continued uniformity and quality of the tungsten powders. Precise chemical specifications have been set up for each of the control points. At the completion of the chemical cycle, ammonium paratungstate is calcined to oxide. The oxide is reduced in a hydrogen atmosphere to form the metal powder.
After reduction, the tung
sten powders are screened and blended. Single blend lots up to 6,000 kilograms are available.
