- Inert Atmosphere Requirements
For simple apparatus for inert atmosphere reactions, the basic requirements are: Inert atmosphere, usually nitrogen or argon, piped into the apparatus. Nitrogen is the most commonly used inert gas, whereas argon is more expensive but does have the advantage that it is denser than nitrogen and is not lost from the apparatus as quickly.

The normal method is to fill these tanks with inert (non-explosive) gas from the ship's boiler flue: it is cleaned and then pumped into the empty tanks, or into the spaces left above the oil in loaded tanks. An inert gas system is required on all new tankers and most existing tankers of 20,000 dwt and above. Equipment duplication

Similar to metals, non-oxidic ceramics are often debinded catalytically, thermally, or with solvents in an inert atmosphere, and then sintered in metallic cold-wall furnaces. This takes place with the exclusion of oxygen in an inert and reactive (hydrogen) atmosphere or in a (high-) vacuum.
