High Purity Tungsten Trioxide
High-purity tungsten or ultra-high-purity tungsten (99.999% or 99.9999%) has high conductivity for electron migration, high-temperature stability and the ability to form stable silicides. It is used as gate, connection and barrier metals in the form of thin films in the electronics industry, and is also used as wiring materials for semiconductors. Certain impurity elements also have an important influence on the properties of specific tungsten materials.
As an important intermediate product for the industrial production of tungsten powder, the purity and performance of tungsten trioxide directly affect the performance of the subsequent tungsten powder.
High purity tungsten trioxide has a yellow or light yellow powder appearance, the product has no inclusions or lumps, its Fisher particle size is 12~25um, and the product is sieved through an 80-mesh sieve.
