Non-evaporable

Describing a substance or material that does not readily vaporize or change into a gaseous state under specified conditions, typically at room temperature or moderate heating. This property is crucial in applications where maintaining the physical form of the substance is essential, avoiding losses due to evaporation. This contrasts with volatile substances that readily become vapors. The term often pertains to liquids, solids, and dissolved materials and is often employed in scientific and industrial contexts focusing on material stability.

Non-evaporable meaning with examples

• The new heat transfer fluid was preferred for its non-evaporable properties, ensuring consistent performance over extended operating periods. Unlike older volatile alternatives, it didn’t need frequent replenishment, resulting in significant cost savings and reduced downtime due to the nature of it's construction. This characteristic made it ideal for this specific application, in the extreme heat transfer systems.
• In vacuum coating processes, a non-evaporable getter (NEG) material is used to absorb residual gases within the chamber. This is an excellent alternative to cryopumping. The absence of evaporation is crucial. It can't become a contaminant because it's specifically designed to interact with the residual gases to make a cleaner vacuum and to make the overall outcome of this process easier.
• The analysis of the dried residue revealed it was composed of non-evaporable components like salts and mineral deposits. Careful handling and preparation were needed to ensure the solution's integrity to find the right outcome. Understanding what remained, what went away and what reacted during the experiment was vital to the results of this test.
• A non-evaporable coating was applied to the sensors to protect them in a harsh environment. This process increased the product's life. It was chosen to resist erosion, corrosion, and to provide a stable physical barrier against heat. The material was specifically designed to withstand extreme temperatures without any noticeable degradation, guaranteeing continuous operation.
