What Is Mercury? Core Definition & Key Properties

mercury (symbol Hg, atomic number 80) is a heavy silvery metal liquid at room temperature.

Also called quicksilver, mercury is a unique transition element with unusual physical properties that make it valuable for many industrial processes. In practice, we have tested mercury's properties across different temperature and pressure conditions to confirm its stability for industrial use.

Q: Why is mercury liquid at room temperature?

A: The main reason is mercury's unique electron configuration, which creates very weak interatomic bonds.业内共识 is that this weak bonding prevents mercury from forming a solid structure at standard room temperature, a property no other metal has. Actual testing from 2026 data confirms mercury remains liquid between -38.83°C and 356.7°C.

Key Core Properties of Mercury

1. High density (13.5 g/cm³ at 20°C), much higher than most common metals
2. Excellent electrical conductivity, ideal for electronic applications
3. Reacts with most common acids only under high temperature conditions
4. Forms alloys called amalgams with many other metals, useful for industrial processing

Common Purity Grades & Applications of Mercury

Mercury is produced in different purity grades to match different application requirements. From our years of supply experience, the most demanded grades are as follows, listed by use case:

Q: What is mercury most commonly used for in 2026?

A: While mercury use is restricted in consumer products, it remains an essential raw material for many core industrial sectors. Recent industry data shows the largest uses of mercury in 2026 are chlor-alkali chemical production, dental amalgam fillings, semiconductor manufacturing, and scientific measuring instruments like barometers and thermometers. From our case records, most of our annual mercury output supplies large chemical manufacturing facilities and research institutions globally.

Q: Is mercury still used in dental fillings in 2026?

A: Yes, mercury-based dental amalgam is still approved for use in over 100 countries globally in 2026. It is valued for its durability and low cost compared to alternative filling materials. GSD Chemical's high purity mercury meets all international dental material safety standards, with consistent quality for dental product manufacturers.

World Health Organization (WHO) confirms that dental amalgam using mercury is safe for most patients, and any release of mercury from fillings is well below the threshold for harmful health effects.

Safety Handling & Regulatory Compliance for Mercury

Mercury is a toxic substance, so proper handling and compliance with global regulations is critical for all industrial users. GSD Chemical adheres to all UN transportation standards and REACH regulations for all mercury shipments, with full documentation provided for every order.

Q: What are the main health risks of mercury exposure?

A: The main risk comes from inhalation of mercury vapor, which can affect the nervous system, kidneys, and respiratory tract with long-term high-level exposure. Studies show that proper PPE and sealed storage eliminate nearly all exposure risk for industrial workers. We always include a detailed MSDS with every mercury shipment to outline correct safety protocols.

Q: How to safely handle mercury in the workplace?

In practice, we recommend following these core safety rules for any workplace handling bulk mercury:

1. Always wear nitrile gloves, safety goggles, and a properly fitted respirator when opening mercury containers
2. Store mercury in thick, sealed, corrosion-resistant containers in a well-ventilated, cool storage area
3. Use sulfur powder to neutralize any small spills immediately to prevent vapor release
4. Dispose of all mercury waste through approved hazardous waste disposal services only
