What is the Difference Between Amalgam and Cinnabar?
🆚 Go to Comparative Table 🆚Amalgam and cinnabar are both substances that contain mercury, but they have different properties and uses. Here are the key differences between the two:
- Amalgam:
- Amalgam is an alloy formed by combining mercury with another metal, such as silver, tin, or copper.
- It is commonly used in dental fillings and certain industrial applications.
- Dental amalgam is a metallic alloy primarily consisting of mercury, silver, tin, and copper.
- Cinnabar:
- Cinnabar is a mineral, specifically the primary ore of mercury.
- Cinnabar is a bright scarlet to brick-red form of mercury(II) sulfide (HgS).
- It is not typically used in dental restorations or industrial applications like amalgam.
In summary, amalgam is a man-made alloy used in dentistry and industry, while cinnabar is a naturally occurring mineral that serves as the primary ore of mercury.

Comparative Table: Amalgam vs Cinnabar
Here is a table comparing the differences between amalgam and cinnabar:
Property | Amalgam | Cinnabar |
---|---|---|
Definition | Amalgam is a mercury-based alloy consisting of a mixture of mercury and one or more other metals. | Cinnabar is a red mineral containing mercury(II) and sulfur. |
Composition | Primarily composed of mercury along with one or more other metals. | A crystalline compound of mercury(II) sulfide (HgS). |
Formation | Formed through the process of amalgamation, which involves the combination of metals with mercury through the application of heat, resulting in a solid, homogeneous substance. | Naturally occurring mineral, often found in association with volcanic rocks and hydrothermal veins. |
Uses | Used in various applications such as dental fillings, thermometers, and barometers. | Traditionally used in Chinese medicine and as a pigment. |
Toxicity | The toxicity of amalgam depends on its composition and the presence of other mercury compounds. | The solubility and bioavailability of cinnabar are quite low, but it can release mercury vapor when heated. |
In summary, amalgam is a mercury-based alloy, while cinnabar is a red mineral containing mercury(II) and sulfur.
