Tungsten aluminum powder is a kind of doped tungsten powder, which is prepared by tungsten powder mixed with aluminum. Its aluminum content is very low, and the oxygen content can be determined by the pulse heating coulometry.
Aluminum is volatile at high temperatures, which may affect the determination of oxygen content. So It usually adopts the pulse heating coulombic oxygen method, this method is accurate, reliable, sensitivity and the minimum detection limit of the instrument can meet the production and analysis requirements.
Tungsten aluminum powder should be sealed and stored in a dry, cool environment. It should not be exposed to the air for a long time, to prevent reunion occurred damp, affecting the dispersion performance and the use of results.
