Ultra purity tungsten powder refers to ultra-high-purity molybdenum powder with excellent characteristics such as uniform particles, high activity, and large specific surface area. It can be applied to special high-temperature devices, VLSI circuits, and semiconductor transistors.
Characteristic
Ultra purity tungsten powder has uniform particles, high purity, high activity, and large specific surface area. After passivation, the oxygen content can be controlled below 1%.
Applications
It can produce high temperature devices with special requirements;
It is used for pure tungsten addition in the field of precision alloy casting;
Ultra purity tungsten powder and its silicide can be used for VLSI as resistance layer, diffusion barrier layer, etc.
In a metal oxide semiconductor type transistor, it serves as a gate material and a connection material.
