Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres
Advanced Engineering Materials, EarlyView.This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Particle Size Distribution of Copper Nanosized Powders Prepared by Pulsed Wire Discharge
IEEJ Transactions on Fundamentals and Materials, 2005 Copper nanosized powders have been prepared by pulsed wire discharge (PWD). The charging voltage and ambient gas pressure dependence on the particle size distribution has been investigated. The particle size ranged from 10 to 100 nm, and the distribution profile agreed with that of log-normal distribution.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.
