Some Properties of the Phosphate Group (General Concepts)

4.4 Some Properties of the Phosphate Group (General Concepts). For a better understanding of those properties of nucleotides which stem from the presence of a phosphate group in their molecules, we must first of all review the currently adopted concepts regarding the structure of the phosphate group and also discuss, using such simple analogues of nucleotides as alkyl phosphates and similar

Mineral Phosphates Britannica

Mineral Mineral Phosphates: Although this mineral class is large (with almost 700 known species), most of its members are quite rare. Apatite [Ca5(PO4)3(F, Cl, OH)], however, is one of the most important and abundant phosphates. The members of this group are characterized by tetrahedral anionic (PO4)3– complexes, which are analogous to the (SO4)2– groups of the sulfates.

phosphate mineral Description, Uses, & Facts Britannica

Phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid. Phosphates can be grouped as: primary phosphates that have crystallized from a liquid; secondary phosphates formed by the alteration of primary phosphates; and rock phosphates formed from phosphorous-bearing organic material.

PHOSPHATE ROCK (FERTILIZER) Chemicalland21

'Rock Phosphate' is a sedimentary rock composed of phosphate minerals high enough, especially apatite. It is used directly in fertilizer and as a source of phosphorous compounds. Apatite includes 10 mineral species and has the general formula X 5 Y(PO 4 ) 3,where X is usually Ca 2+ or Pb 3+ and Y is F,Cl,or OH .

Phosphorus Element information, properties and uses

Phosphorus is also important in the production of steel. Phosphates are ingredients in some detergents, but are beginning to be phased out in some countries. This is because they can lead to high phosphate levels in natural water supplies causing unwanted algae to grow. Phosphates are also used in the production of special glasses and fine

Phosphate conversion coating Wikipedia

Phosphate coating is used on steel parts for corrosion resistance, lubrication, or as a foundation for subsequent coatings or painting. It serves as a conversion coating in which a dilute solution of phosphoric acid and phosphate salts is applied via spraying or immersion and chemically reacts with the surface of the part being coated to form a layer of insoluble, crystalline phosphates.

Metal Profile: Iron Properties and Characteristics

Jan 12, 2020· History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
