- This metal is like mercury but safe - Interesting Engineering
Imagine holding a metal that can melt in your hands at room temperature! That’s gallium for you Discovered in 1874, the unique metal was named after the Latin term for France, Gallia
- Gallium Boils at 4,044 Degrees F, But Will Also Melt in Your Hand
Yup, the melting point of gallium is just 85 6 degrees F (29 8 degrees C), which means that it melts into a mirror-like puddle in your hot little hand In its liquid form, gallium looks a lot like mercury, but gallium isn't toxic like mercury so it's safer to handle (although it can stain your skin)
- 15: Dental Amalgams - Pocket Dentistry
As the content of liquid mercury in the mixture decreases by the formation of precipitates, the mixture hardens This process is called amalgamation and the material has been used for restoring tooth structure The first use of amalgam for tooth filling was recorded in the Chinese medical literature in 659 A D
- Gallium is a liquid metal element like mercury but nontoxic
You definitely shouldn't mess around with mercury, but if you want a safe, similar, tactile experience, a metal called Gallium is widely available online It's melting point is about 85
- Alternative to Mercury with Similar Density and Appearance at . . . - Reddit
Any suggestions to a liquid with a comparable density and appearance to Mercury at room temperature, that is not harmful? It doesn't have to be a metal; metallic ink, for example, could work
- Liquid Metal Gallium Alloy Galinstan - Looks like Mercury!
Here is a video showing some properties of Galinstan, a Gallium Indium Tin alloy that is liquid at room temperature This stuff is pretty much non-toxic, but is also expensive A eutectic alloy of
- Nontoxic Liquid Metal Alloy Could Substitute For Mercury
NewMerc, Ltd (Blacksburg, VA), has begun producing a nontoxic, electrically-conductive, liquid metal alloy alternative to mercury Although mercury is highly toxic, it is still used applications ranging from electrical switches and sensors to thermometers and dental fillings
- What Do You Know About Mercury? - NYSDEC
Dental amalgam is an alloy that is made of 43 to 54% mercury combined with a percentage of silver, tin, zinc and copper Mercury forms very useful compounds with other elements Some of these mercury compounds are mercuric oxide, mercuric sulphide, mercuric chloride, and mercuric nitrate
- Dont Mess With Mercury. Play With Gallium Instead!
Luckily, there's a wonderful replacement available Gallium closely mimics mercury's otherworldly appearance, though unfortunately lacks its prodigious density But what gallium lacks in mass, it makes up for with other fascinating properties
