7 Surprising Applications Of Mercury

Quick Links :

Mercury, a chemical element with the symbol Hg, has been known to humans for thousands of years. It is a silvery-white, heavy, and dense metal that is also a liquid at room temperature. Despite its toxic nature, mercury has been used in various applications throughout history. Here are 7 surprising applications of mercury that showcase its versatility.

Mercury's unique properties make it an ideal substance for various uses. Its high density and ability to form amalgams with other metals have led to its use in dentistry, thermometers, and thermostats. However, its toxicity has raised concerns about its safety and environmental impact. In this article, we will explore some of the surprising applications of mercury and discuss its benefits and drawbacks.

Mercury in Dentistry

One of the most well-known applications of mercury is in dentistry. Mercury is used to make dental amalgam, a mixture of mercury, silver, tin, and copper. Dental amalgam is used to fill cavities and repair teeth. Mercury's ability to form amalgams with other metals makes it an ideal substance for this application.

However, the use of mercury in dentistry has been controversial due to concerns about its toxicity. Mercury is a potent neurotoxin that can cause damage to the brain, nervous system, and kidneys. Exposure to mercury has been linked to a range of health problems, including tremors, memory loss, and birth defects.

Benefits of Mercury in Dentistry

Despite the risks, mercury has been used in dentistry for over 150 years. Its benefits include:

• Durability: Dental amalgam is highly durable and can last for many years.
• Strength: Mercury's ability to form amalgams with other metals makes it a strong and durable material.
• Cost-effective: Dental amalgam is relatively inexpensive compared to other materials.

Risks of Mercury in Dentistry

However, the risks of mercury in dentistry cannot be ignored. Exposure to mercury has been linked to a range of health problems, including:

• Neurological damage: Mercury can cause damage to the brain, nervous system, and kidneys.
• Birth defects: Exposure to mercury has been linked to birth defects and developmental delays.
• Environmental impact: Mercury is a potent pollutant that can harm the environment.

Mercury in Thermometers and Thermostats

Mercury is also used in thermometers and thermostats due to its high coefficient of expansion. This means that mercury expands and contracts rapidly in response to temperature changes, making it an ideal substance for measuring temperature.

Mercury thermometers are widely used in laboratories, hospitals, and homes. They are relatively inexpensive and accurate. However, the use of mercury in thermometers has been phased out in many countries due to concerns about its toxicity.

Benefits of Mercury in Thermometers and Thermostats

The benefits of mercury in thermometers and thermostats include:

• Accuracy: Mercury thermometers are highly accurate and reliable.
• Cost-effective: Mercury thermometers are relatively inexpensive compared to other materials.
• Durability: Mercury thermometers can last for many years with proper care.

Risks of Mercury in Thermometers and Thermostats

However, the risks of mercury in thermometers and thermostats cannot be ignored. Exposure to mercury has been linked to a range of health problems, including:

• Neurological damage: Mercury can cause damage to the brain, nervous system, and kidneys.
• Environmental impact: Mercury is a potent pollutant that can harm the environment.

Mercury in Lighting

Mercury is also used in fluorescent lighting, including compact fluorescent lamps (CFLs). Mercury is used to create the electrical arc that produces light. CFLs are energy-efficient and last longer than incandescent bulbs.

However, the use of mercury in CFLs has raised concerns about its toxicity. Mercury is released into the environment when CFLs are broken or disposed of improperly.

Benefits of Mercury in Lighting

The benefits of mercury in lighting include:

• Energy efficiency: CFLs are energy-efficient and last longer than incandescent bulbs.
• Cost-effective: CFLs are relatively inexpensive compared to other materials.

However, the risks of mercury in lighting cannot be ignored. Exposure to mercury has been linked to a range of health problems, including:

• Neurological damage: Mercury can cause damage to the brain, nervous system, and kidneys.
• Environmental impact: Mercury is a potent pollutant that can harm the environment.

Mercury in Batteries

Mercury is also used in batteries, including button cell batteries and mercury-oxide batteries. Mercury is used to create the electrical connection between the positive and negative terminals.

However, the use of mercury in batteries has been phased out in many countries due to concerns about its toxicity. Mercury is released into the environment when batteries are disposed of improperly.

Benefits of Mercury in Batteries

The benefits of mercury in batteries include:

• Long-lasting: Mercury batteries can last for many years with proper care.
• Reliable: Mercury batteries are reliable and consistent.
• Cost-effective: Mercury batteries are relatively inexpensive compared to other materials.
