Dewar tanks materials
The primary function of a dewar tank is to maintain the low temperatures of the cryogenic liquids it holds.
The primary function of a dewar tank is to maintain the low temperatures of the cryogenic liquids it holds. The vacuum insulation between the inner and outer walls minimizes heat transfer through conduction and convection. Some dewars also incorporate multi-layer insulation (MLI), which consists of several reflective layers that further reduce heat transfer by radiation.
Dewar tanks are constructed using materials that can endure extremely low temperatures without becoming brittle. Stainless steel and aluminum are popular choices due to their strength, resistance to corrosion, and ability to handle cryogenic conditions. The choice of material also influences the tank’s weight and portability.
