Uses of Silk

Silk is a natural fiber that is used to create materials. It is obtained from the cocoon of the mulberry silk worm which is reared in captivity. Silk is also made by a variety of other insects that undergo metamorphosis and some insects such as spiders that are web spinners. Silk has a triangular prism structure and reflects light in different directions giving it a shimmery appearance. It is lightweight, smooth and considered to be one of the most luxurious materials available. Let’s examine the uses of silk in the world today.

Uses of Ruthenium

Ruthenium is a rare silvery-white metal that belongs to the “platinum group” of metals, which means that it is not very chemically reactive. It is the 44th element on the periodic table and is represented by the symbol Ru. It was discovered in 1844 and is found in ores that contain other metals from the platinum group. It is estimated that there are only 5,000 tonnes of ruthenium on Earth and about 12 tonnes are obtained each year, mostly as a by-product of copper and nickel mining. Despite its rarity, ruthenium has many important applications.

Uses of Platinum

Platinum is a chemical element with an atomic number of 78 and the chemical symbol of Pt. It is a dense, pliable, precious metal with a gray-silver luster. Platinum is one of the rarest elements in the Earth’s crust and is mostly mined in South Africa. Platinum usually contains some nickel and copper ores and is generally non-reactive. It is corrosion resistant even at high temperatures and is considered to be a noble metal. Platinum has many uses in the modern world. Let’s examine some of those used in this article.

Uses of Hydrochloric Acid

Hydrochloric Acid is a highly corrosive chemical compound comprised of hydrogen chloride and water. Hydrochloric acid is also known as spirits of salt or muriatic acid. It is colorless and has wide ranging uses and applications. Hydrochloric acid is a natural part of gastric acid in humans and animals. It is non-flammable, but is extremely corrosive and toxic in high concentrations. Hydrochloric acid was first discovered in the 13th century by European alchemists and by the 16th century free hydrochloric acid was formally described by Libavius. Let’s take a look at some of the most common applications of Hydrochloric acid.

Uses Of Palladium

Palladium is the 46th chemical element on the periodic table, represented by the chemical symbol Pd. It is a shiny silver metal, which is often found in an alloy with gold or platinum. The most common commercial source of the metal is in nickel-copper deposits. Over 200 tonnes is produced each year for the various important applications of this metal.

Uses of Nitric Acid

Nitric acid is a highly corrosive acid that is made up of oxygen, nitrogen and hydrogen. Nitric acid is usually colorless, but can become yellowish if stored for a long period of time. It is used in the laboratory for many purposes and it has many other important applications as well.

Uses of Citric Acid

Citric acid is a natural acid that exists in many fruits and vegetables, but is well known for high concentrations in some citrus fruits such as lemons and limes. Citric acid can also be produced by feeding sugar to a certain type of mold called Aspergillus niger. This technique was discovered in 1917 and is still used today to produce citric acid. This acid has many important applications and more than a million tonnes are made each year.

Uses of Rhodium

Rhodium is a chemical element represented by the chemical symbol Rh and the atomic number 45. It is a hard silvery-white metal and is classified as a transition metal from the platinum group. It is a rare element that is only found in platinum ore or nickel ore, from which it is obtained commercially. It is extremely resistant to corrosion and this characteristic makes it viable for a number of different applications.

Uses of Kaolinite

Kaolinite is a clay mineral with the chemical formula Al2Si2O5(OH)4. It is a soft mineral that is usually white, but it can appear blue or rust colored due to impurities. It is a very common mineral and in mined in many countries of the world. When a rock contains a lot of kaolinite it is referred to as kaolin or China clay. Let’s take a look at the most common applications of this mineral.

Uses of Xenon

Xenon is a colorless and odorless noble gas, which means it is a gas with very low reactivity. It is represented on the periodic table with the symbol Xe and has an atomic number of 54. It occurs naturally in trace amounts in the atmosphere and is obtained as a byproduct when air is separated into oxygen and nitrogen. Xenon was first discovered in 1898 by William Ramsay and Morris Travers, but the first use for this gas wasn’t found until the 1930’s. Let’s take a look at some of the most common applications of Xenon.
