INDUSTRY COMPONENT

Mercury Amalgam

Mercury amalgam is a mercury-based alloy used in UV-C germicidal lamps to generate ultraviolet light for disinfection.

Component Specifications

Definition
Mercury amalgam is a specialized component in UV-C germicidal lamps where mercury is alloyed with other metals (typically bismuth, indium, or gallium) to create a stable solid or paste form. This amalgam controls mercury vapor pressure within the lamp, enabling precise UV-C emission at 254 nm wavelength for effective microbial disinfection while improving thermal stability and operational lifespan compared to pure mercury lamps.
Working Principle
When electrical current passes through the mercury amalgam in the UV-C lamp, it excites mercury atoms, causing them to emit ultraviolet radiation at 254 nm. The amalgam formulation regulates mercury vapor pressure, ensuring consistent UV output across varying temperatures and preventing mercury condensation at lower temperatures.
Materials
Mercury (Hg) alloyed with bismuth (Bi), indium (In), or gallium (Ga) in precise ratios (typically 50-80% Hg by weight), encapsulated in quartz or special glass envelopes resistant to UV radiation and mercury corrosion.
