Osmium is a chemical element with the atomic number of 76 and the chemical symbol Os. It is part of the platinum family and is a transition metal. It is blue-gray or blue-black and is the densest naturally occurring stable element on earth. It is known for being hard and brittle and well as extremely durable. Osmium has the highest melting point and lowest vapor pressure of the platinum group. It occurs naturally as an alloy with other platinum metals. It remains lustrous even at high temperatures and is difficult to work. When the metal oxidizes it releases a toxic agent that can cause lung congestion, skin damage, or eye damage. Due to this, osmium is very rarely used in its pure form and is most often combined with other metals. So what is osmium used for in the world today? Read on to find out.
Technetium is a chemical element that is mostly synthesized with only a small amount found naturally. This is due to the fact that technetium is an unstable (radioactive) element. It is a silvery-gray transition metal that is naturally found in uranium ore. It has an atomic number of 43 and the chemical symbol of Tc. When in powdered form Technetium burns in oxygen. It is highly resistant to corrosion with no form of hydrochloric acid able to corrode it. Technetium has a small number of niche uses in the world today, read this article to find out more.
Tantalum is a hard, blue-grey, transition metal that is rarely found in elemental form. It is a chemical element with the symbol Ta and an atomic number of 73. Tantalum was previously known as Tantalus after a greek mythological character. It is highly corrosion resistance and chemically inert making it sought after for use in technology such as cell phones, DVD players and computers. This article will outline the uses of tantalum in the world today.
Graphite is a grey semimetal that is an allotrope (form) of carbon. Graphite is naturally occurring and can be found in three different forms; flake granite, amorphous granite and vein (lump) granite. Graphite can also be made synthetically for a variety of uses. Graphite is considered the most stable form of carbon in normal conditions and has many applications. This article will outline to uses of graphite in the world today.
Fluorite, also called fluorspar, is a mineral that consists of the compound calcium fluoride (calcium and fluorine). It is a common mineral and is often found in association with metallic minerals. It is also a common mineral in granite and other igneous rocks. It is estimated that the largest deposits of fluorite occur in South Africa, Mexico and China. China currently produces the largest amount of this mineral in the world. The following are some of the most common applications of fluorite.
PVC, correctly called polyvinyl chloride, is a manmade plastic made from a blend of synthetic resins and polymers. PVC can be made rigid or soft, with the use of plasticizers. Many other additives can also be used to improve the characteristics of this plastic. PVC is a very versatile material and is popular for many uses because it is much cheaper than alternative materials. It is the third most commonly produced plastic on the planet and has a number of important applications.
Barium is a chemical element with the atomic number 56 and is represented by the chemical symbol Ba. It is a soft silvery metal that quickly oxidizes in air. This means that the free metal is never found naturally and is mostly extracted commercially from barite. This rapid rate of oxidation also reduces the available applications for the metal, but many barium compounds have important uses.
Rubidium is a highly reactive, silvery-white metal. It is a chemical element that is represented by the atomic number 37 and the chemical symbol Rb. This metal was discovered in 1861 by German chemists. Naturally occurring rubidium is a relatively common element in the crust of the Earth. Most commercial rubidium is extracted from lepidolite, which is a mineral that contains about 0.3-3.5% of the element. Rubidium has few commercial applications, but the following are the most common applications of element.
Phosphoric acid is mineral acid which molecules that can combine themselves in a number of different ways. These different combinations are referred to as phosphoric acids. Phosphoric acid is a white solid that melts to form a colorless, viscous liquid. High concentrations of the liquid are corrosive. Phosphoric acid is non-flammable and non toxic. Let’s examine what phosphoric acid is used for in the world today.
Quinine is a naturally occurring white crystalline substance that is found in the bark of the cinchona tree. It has fever reducing, antimalarial, anti-inflammatory and analgesic properties. Quinine has a bitter taste and is found in very small quantities in tonic water. When exposed to direct sunlight quinine becomes florescent. For many years the main use of Quinine was to treat malaria, let’s examine what quinine is used for in the world today.
