The application fields of liquid silver mercury (mercury) mainly include the following aspects:
Industrial application: Mercury is often used to manufacture various electronic devices, such as thermometers, sphygmomanometers, flow meters, liquid level gauges, controllers, barometers, mercury rectifiers, etc. In addition, mercury is also used to manufacture fluorescent lamps, ultraviolet lamps, movie projection lamps and X-ray tubes, etc.
Medical field: In the past, mercury was used in certain drugs and medical equipment, such as bactericides and disinfectants. Nevertheless, due to its high toxicity, these uses have been strictly restricted. At present, mercury-containing sphygmomanometers and thermometers are gradually being replaced by electronic devices.
Scientific research: Mercury is still used in chemical experiments and physical research for certain specific experiments and measurements. Due to its unique physical and chemical properties, mercury still has a certain use value in scientific research.
Mining industry: In gold mining, mercury is sometimes used to extract gold. In addition, in mining and oil extraction, mercury is also used to separate valuable metals or extract crude oil residues from deep storage areas of oil wells.
Battery manufacturing: Mercury is used in the production of some specific types of batteries.
Although mercury is widely used in many fields, due to its toxicity, it must be used in strict accordance with relevant regulations and safety standards to prevent harm to the human body and the environment.
