Ever wondered how high-quality metal powders are made? Well, you’ve come to the right place! Today, we’re diving into the fascinating world of electrode inert gas atomisers. Buckle up, because this journey is going to be both informative and engaging!

Overview of Electrode Inert Gas Atomisers

Electrode inert gas atomisers are cutting-edge devices used to produce fine metal powders. These powders are crucial in various industries, from aerospace to pharmaceuticals. But what makes these atomisers so special? Let’s break it down:

  • Process: Electrode inert gas atomisation involves melting a metal using an electrode and then dispersing it into fine droplets using an inert gas. These droplets cool and solidify into powder.
  • Precision: The process allows for precise control over particle size and distribution.
  • Purity: The use of inert gas prevents oxidation, ensuring high-purity metal powders.
