Platinum - Element information, properties and uses

Probably the oldest worked specimen of platinum is that from an ancient Egyptian casket of the 7 th century BC, unearthed at Thebes and dedied to Queen Shapenapit. Otherwise this metal was unknown in Europe and Asia for the next two millennia, although on the Pacific coast of South America, there were people able to work platinum, as shown by burial goods dating back 2000 years.

Limestone | Types, Properties, Composition, Formation, Uses

Purified, it is delivered to bread and cereals as a supply of calcium. Calcium levels in tle feed are supplemented with it, together with for chicken (when ground up). It may be used for remineralizing and increasing the alkalinity of purified water to prevent pipe corrosion and to repair important nutrient tiers.

Chemistry for Kids: Elements - Titanium

Titanium is the first element in the fourth column of the periodic table. It is classified as a transition metal. Titanium atoms have 22 electrons and 22 protons. Characteristics and Properties Under standard conditions titanium is a hard, light, silvery metal. At room temperature it can be brittle, but it becomes more malleable at higher

How silicon is made - material, making, history, used

Depending on the grade, silicon metal contains 98.5-99.99% silicon with trace amounts of iron, calcium and aluminum. Cooling/Crushing 3 Oxidized material, called slag, is poured off into pots and cooled. The silicon metal is cooled in large cast iron trays about 8 ft (2.4 m) across and 8 in (20 cm) deep.

Iron - Element information, properties and uses | Periodic

The ancient Hittites of Asia Minor, today’s Turkey, were the first to smelt iron from its ores around 1500 BC and this new, stronger, metal gave them economic and political power. The Iron Age had begun. Some kinds of iron were clearly superior to others depending on …

Alkaline earth metal - Wikipedia

The alkaline earth metals are six chemical elements in group 2 of the periodic table.They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.. Structurally, they (together with helium) have in common an outer s

Metal - Wikipedia

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical element such as iron; an alloy such as
