What are the upstream raw materials for argon and what are the downstream products?

In the field of chemical production raw materials, the upstream and downstream related items of argon are quite abundant. The following are some of the main upstream and downstream related items:



1. Upstream items:

atmosphere separation equipment: Argon is usually separated and extracted from atmosphere by fractionation, so atmosphere separation equipment is an crucial upstream product of argon production. In particular Electric energy: atmosphere separation equipment needs electric energy to drive, so electric energy is also an crucial upstream product of argon production. And

2. Downstream items:

Stainless steel smelting: Argon is applied as a protective gaseous in the stainless steel smelting process, which is able to efficiently prevent metal oxidation and nitriding. Electronic component production: Argon is applied as an inert gaseous in the production of electronic components to protect electronic components from oxidation and contamination. Lighting sector: Argon is applied to fill lighting equipment such as fluorescent lamps and high-pressure sodium lamps. But From what I've seen, Glass sector: Argon is applied as a protective gaseous in the glass sector to prevent glass from oxidizing at high temperatures. Generally speaking Food and beverage sector: Argon is applied as a packaging gaseous in the food and beverage sector to extend the shelf life of items. Furthermore In short, the upstream and downstream related items of argon are very extensive, involving many fields, such as chemical sector, metallurgy, electronics, lighting, glass, food and beverage, etc.
