Pallasites contain big, beautiful olive-green crystals - a form of magnesium-iron silicate called olivine - embedded entirely in metal. Sometimes the olivine does not occur as a single crystal but as ...

About 400 kilometers northwest of Sydney, just south of Dubbo, lies a large and interesting body of rock formed around 215 ...

copper crystals. You can see the result in the video below. To grow pure metal crystals, he used copper wire and copper sulfate. He also used a special regulated power supply to create a low ...

Both rubies and emeralds are minerals, which is a type of rock with a consistent chemical composition and a highly ordered ...

They combined iron, nickel, and zirconium ... confirming that the resulting alloy had the same crystal structure as tetragonal transition-metal zirconides, a family of promising superconducting ...

When it is exposed to air, the iron begins to rust. This rusting process produces heat. The second contains a solution of the chemical sodium acetate and a small metal disc. When the disc is bent, ...

When a liquid metal cools and turns into a solid, its atoms come together to form crystals. The structure of these crystals is not perfect. Sometimes an extra layer of atoms squeezes between other ...

Iron is a metal in group VIII of the periodic table with atomic number 26, an atomic weight of 55.85, and a density of 7.86. It has a melting point of 1539 C.

Metals are the only substances that are magnetic. But some metals are magnetic and some are not. The most common magnetic metal is iron. You don't see too many objects made of pure iron but you do see ...
